Why Does A Well Pump Keeps Tripping Breaker?

The situation can be frustrating when a well pump or submersible water pump keeps tripping the breaker. Before replacing the well pump, it’s always better to find out the reasons behind the issue.

These are the 7 most common reasons for a well pump to keep tripping its breaker –

1. Overloading The Circuit

One of the main reasons for the breaker tripping issue is overloading. Overload normally means more power input than the device can handle.

When the circuit is overloaded, the circuit breaker may start to act weirdly. In such circumstances, tripping is a common outcome.

Solution: When the overloading issue happens, you have to do something to make it go away. Removing the clogs in the circuit is the way to get the job done here.

2. Fault In The Wiring

Another reason for the tripping problem is faulty wiring. The wires may be short or damaged. In such cases, you may find the tripping issue as an outcome of the wiring fault.

There may be a loose connection in the electrical box too. You may find a similar outcome in this situation also.

Solution: Check the entire wiring of the well pump. If you don’t think you will be able to inspect, hire a professional. After that, fix the damage to the wiring.

3. Weak Breaker

The breaker may also trip when the breaker itself is faulty. It’s a common instance that appliances get older and lose their temperament. If that’s the case, the breaker won’t be able to perform its function as it’s supposed to.

Solution: When the breaker itself is weak or faulty, you won’t have any option but to replace the breaker. Try buying a premium breaker. Otherwise, you may face issues again with it.

4. Well Pump Motor Defect

Don’t be surprised. A well pump may keep tripping when there’s a defect in the well pump motor. Sometimes the well pump performs poorly due to a problem with the pump’s motor.

So, the pump tripping problem isn’t impossible to fix when there’s a problem with the motor. That’s why checking the pump motor is another crucial step to finding the root of the tripping problem.

Solution: Replacing or changing the pump motor is the only option here. Similar to the breaker, try to get a good-quality pump motor as a replacement.

5. Clogged Impeller

Sometimes the impeller may get clogged. As the impeller is a major component of a well pump, the clogging of it’s a big concern. You may face problems like continuous breaker tripping until the clog is fixed.

Solution: Try to remove all the clogs within the impeller. To do that, you have to take the cover or seal of the casing first. Then, you will see the impeller. Remove it from the machine and then clean the impeller properly.

6. Bad Seals

The seals of the well pump may also be why your well pump keeps tripping its breaker.

When the breaker is in a position where the mechanical seal has failed, you may face the tripping issue. Things like this become common since a failed seal allows water to enter the pump parts.

Solution: When the seal problem is the main issue, you will have to work with the seal. Try changing the seal or fixing the leak in the seal.

7. Pressure Switch

Sometimes you may think, will a bad pressure switch trip the breaker ? Yes, a bad pressure switch may also be the reason for a well pump to trip its breaker.

A pressure switch can become weak or bad due to the burnt or bad contacts on the pressure switch. If that happens, it can lead to a situation like tripping the breaker.

Solution: When there is an issue with the pressure switch,  try replacing the bad contacts. They are the main culprit in this situation.

• Can you burn out a well pump?
• Well pump is running but not building pressure.

How To Diagnose The Well Pump When It Keeps Tripping Breaker

Sometimes you may find a new well pump tripping breaker . Old or new, it is important to get to the root of the issue. Besides inspecting the individual symptoms or studying the reasons, a thorough diagnosis of the well pump is also a useful way to get rid of the issue. Follow the next steps to get the job done smoothly.

Inspect The Pressure Switch

The first step in diagnosing the well pump will be to inspect the pump’s pressure switch. Since a bad pressure switch is one of the main reasons that cause the breaker to trip, it’s important to see whether it is okay or not. If you find the pressure switch is faulty, replace it as soon as possible.

Disconnect The Motor

After you are done with the pressure switch, it’s time to work with the pump motor. Sometimes, issues with the pump motor can lead to face problems with the well pump. That’s why you have to disconnect the motor from the pump so that you can surely know what the culprit is.

To disconnect the motor from the pump, turn off the power source first. Then, remove the bolts or turn the clamp to disconnect the motor.

Inspect The Pump Motor

When splitting off the pump motor from the pump is over, you have to inspect the motor to know if it’s okay. You have to measure the motor’s resistance to know the answer.

To do this, taking the help of a digital multimeter is a must. When the reading of the multimeter is below 1 Ohm, the pump motor is not good. You have to replace it.

Fix The Blockages

Fixing the blockages is the next step when you are done with the motor. You have to free the pump from any sort of blockage so that there is no overload issue. Checking the box baskets and pipes of the pump is an important step to clear off the blockages.

Check The Pipes, Pump Boxes, Bearings, And Shafts

When the mentioned four steps are done, you can also check the pipes, the pump box, bearings, and the shafts to see if they’re okay.

Checking these parts is also important as any fault within them may lead to the tripping of the breaker.

Tips To Follow While Working With The Well Pump Tripping Breaker Issue

In most cases, working with the well pump may seem difficult as most of the people doing DIY are not experts. the following tips may help you more-

• Diagnose the well pump thoroughly. You may try to skip one or two parts of the diagnosis if you see them as not important. Do not do that. Even faults within the minor parts of a well pump may lead to a major problem.
• Use a premium pump motor as a replacement. Going for some cheap alternatives is tempting. But if you go for it, you may face a lot of issues with your pump in the future.
• Don’t go for cheap alternatives while replacing bearings or shafts. Just like the motor, cheap bearings or shafts may also cause problems in the future.
• Wear protective gear to ensure the best safety. For instance, use rubber gloves while inspecting the motor of the pump with a multimeter.
• Don’t hesitate to hire a professional when you are out of moves. It’s very much possible to become clueless while working with a well pump. Don’t try to experiment with something. Hire an expert right away.

• Pros and cons of constant pressure well pumps
• Can you use a pool pump for a well pump?

How can you tell if your well pump is bad?

There are a lot of symptoms to give the verdict that your well pump is bad. If you find the symptoms like –

• Muddy or murky water coming out from the tap,
• The tap sputtering water,
• The taste of the water is way off than usual, or
• Loud noises coming out from the pump,

They all indicate the pump has gone bad.

Can a well pressure switch cause breaker to trip?

A well-pressure switch can also cause the breaker to trip. It happens especially when the pressure switch becomes weak or bad to perform properly.

What causes the pump to trip?

The reasons for a pump to trip are a lot. Among them, the main causes are overloading, motor defects, bad circuit breakers, clogged impellers, bad seals, and bad pressure switches. 

The issue we’ve tried to cover here is an irritating and frustrating one. It’s never a pleasing scene to see your well pump keeps tripping breaker.

However, don’t go for the prompt replacement of the pump without diagnosing. Finding the root of the problem will help a lot to solve the problem efficiently and with much less money.

Why Does My Well Pump Keep Tripping the Breaker?

You go to turn on your water only for nothing to come out. Confused, you decide to go check your breaker box, and, sure enough, the circuit breaker on your water pump has tripped. With so many possibilities of what could have happened, it can be hard to determine which one is the culprit. We at Perry’s Pump Repair will go over the five most common reasons your water pump is tripping your breaker and how to fix it. 

5 Reasons Your Water Pump Is Tripping Your Circuit Breaker

Overloaded circuit.

This is one of the leading causes your submersible water pump will trip your breaker. Overloading is a phenomenon that happens when more energy than the circuit can handle passes through the device. The breaker prevents an overload of amperage from harming your pump or anything connected to it. If your water pump is pulling more energy than it should, this can cause the breaker to trip. 

Solution : This is something you’ll want to leave to professionals. Electricity can be extremely dangerous to mess with if you aren’t professionally trained. We suggest you call your local electrician or reach out to us to see if it’s time for a new water pump .  

Rain and Lightning

Here in Gainesville, you know we get almost daily summer thunderstorms and plenty of rain. While these weather conditions are just considered a part of everyday life in Florida, they can occasionally cause problems for your water pump. 

A direct lightning strike can cause your water pump breaker to trip. Much like an overloaded circuit, this is due to the sudden surge of voltage all at once. Rain, on the other hand, can also cause a trip in your circuit breaker. This can be a sign of deeper problems such as deteriorating seals or even FLooding in your pump. 

Solution : If your circuit breaker trips immediately after a lightning strike, you should be able to switch back on fine with no issue. If it pops again, the lightning may have caused damage to your wires, and you’ll want to call in a professional to prevent hazards like an electrical fire. If you believe rain may be the culprit, reach out to us so we can inspect and repair any damaged seals or FLooding.

Leaks in Pump 

Sometimes, your water pump or its outer shell (called the water pump housing) can develop a leak. This can be caused by several different factors such as faulty sealant or using the incorrect coolant. If a leak has developed, it may get water on its wires or inside the pump itself, causing them to short-circuit and trip the breaker. 

Solution : Since it may be hard to determine where the leak is or if it’s safe for an untrained hand to repair, leaks are best left to a professional water pump repair service like Perry’s Pump Repair. One of the best ways to solve this is to keep it from happening in the first place by having a preventative maintenance plan. 

Wiring Issues 

If you’re finding your breaker is tripping as soon as you turn it back on, it may not be an issue with the pump itself but its wiring. The wires could be fried, short-circuited, or simply not connected securely to an electrical source. Occasionally, wire damage can be caused by rodents or other pests that may have chewed through them. 

Solution : Since this is dealing with electricity, you’ll want to have an electrician check your wiring and fix any issues they may see. 

Clogged Impeller

One of the key components of your submersible water pump is its impeller. The impeller uses the energy from the motor to actually pump your water. Through normal use and wear, the impeller may become clogged, causing your circuit breaker to trip. If you’re noticing a frequently tripping breaker and a grinding noise from your water pump, a clogged impeller is likely the issue. 

Solution : Often, this is an easy fix to do at home. Identify where your water pump’s impeller is and simply remove any debris from the area.

On 2021-09-22 by inspectapedia.com.moderator (mod) - pump protection device operation

@Eddie, Just some vague guesses: consider how the pump protection device works. Usually it's monitoring current draw or Amps as an indicator that a pump may be running dry (and thus subject to damage). So we could have low voltage, or a failing sensor in the pump protection device itself, or even a constriction in the piping system (you've checked for this).

(this reader's question, our reply, and the complete discussion is now found at AMPS MEASUREMENT METHODS )

On 2021-09-22 by Eddie

I have a submersible well pump that fills a 5000 gal. storage tank. Pump motor is controlled by a pump motor control with protection device inside, and a Pumpmaster float switch.

My problem, that is now present from original installation, seems to be control of the power to the pump. When float switch activates pump motor, it fills normally for about 10 minutes and then clicks off and immediately back on, and keeps pumping as if nothing happened. A few minutes later it repeats.

Two wires are power in to the switch and two are power out to the pump.

The terminals are labeled at least inside the switch cover showing which two connections are LINE (incoming power) and the other two will be LOAD (to the pump). Watch out: At least one of your wires, the yellow one, is burned and overheated. The problem could be a bad switch (have it replaced) or the pump itself could be bad. Watch out: there is live voltage at those terminals. Touching them with power -on you could be shocked or killed.

Is it possible that a submissive pump die of poor wiring

On 2021-05-07 - by (mod) - no voltage found on wires to pump

@Sam Smith, To answer with confidence I would need to know more about how and where you made your tests and also whether or not you have one simple pressure control switch or a switch that is in turn operating a 240 volt relay control showing at the top of this page. In general you would not expect to see voltage on the wires to the pump unless the pressure control switch was in the closed position. At that point if you're not seeing voltage at the pressure control switch on the pump wires and then I suspect the problem is the switch or relay.

On 2021-05-07 by Sam Smith

I'm showing 240 on the 2 wires of the relay coming from the power box. However, I'm not showing any voltage on the wires coming from the pump. I know I need to go towards the pump to see if there is another junction box and if so if it's showing 240 there. However, if the wires are ok is it likely that the water pump has gone bad?

On 2021-05-02 - by (mod) - where do we measure 220V?

@Tom, with two wires and 220 volts I would expect you would get 220 volts between the two wires coming from your electric panel. Are we on the same page here?

This is a big world water pump 220 volts 2 wire

With the closed circuit on the pressure switch the voltage reads 250 volts on one leg and 0 voltage on the other leg

I checked the voltage on the line and load on the pressure switch one side is 250 and the other side is 0

On 2021-02-08 - by (mod) - wiring a 120V pump up to 240V is likely to damage the pu,p

Edwin Unfortunately, sending 220VAC to a motor wired for 120VAC may damage the motor if in fact you fed it 220 volts; if you just fed one leg and thus 120V to the pump it may be ok, but you want to use the proper pressure control switch too.

On 2021-01-24 by (mod) - unbalanced voltage on 2 legs of a 240VAC pump circuit

That sounds odd indeed, Jarry; I'd expect around 120VAC on each leg of a 240V circuit when tested from leg to ground, and around 240VAC when tested leg-to-leg. You could have a damaged wire enroute to the pump or a pump motor winding that's shorting. Sorry to say you may need to pull the pump to check wiring and pump motor Do keep me posted; what you find will help others.

ok the deep well pump i installed 2 years ago quit,,, its a 220 v 3 hp about 100 foot deep,,,,

well i had replaced the gauge and pressure switch when i put it in,,, its a 2 wire pump........

ok so i thought i tested circuits,, it sits like many below ground and the manual shut off was a fused box ......

so after i tested them and no breakers were tripped ,,,, i checked voltage and the voltage with wires on supply to fuse box disconnected show 120 on each,,, then i connected them and coming from the new breaker box they show 120 each side,,,, and good solid ground,,,,

but when i connect them to the pressure switch and pump and turn them on the one leg on the pressure switch goes to 168 and the other is like 78 v so the pump isnt working, i did unhook wires from the pressure switch and the continuity tester shows one leg and ground making continuity the other is ope.n. this pump being a 2 wire only has the pressure switch no control box my email is [email protected]

On 2021-01-18 - by (mod) - is the problem the pump or a leak in piping?

Are you certain that the problem is that the pump isn't running as opposed to a running pump but a leak or piping problem?

On 2021-01-17 by Greg

So I bypassed my pressure switch and starter box to test the 11 year old pump at my parents place. It had proper voltage and didn't kick on. So I replaced the pump with a brand new one. When I powered the system up nothing happened so I started trouble shooting the system as I always have. Everything tested just fine but still nothing. So I once again ran a jumper wire from the supply at the emergency shut off straight to the pump and still it did nothing.

What are the causes of continue tripping off of over load switch on residential submersible pump

On 2020-07-29 by Robert

When my well pump comes on my line voltage goes down. I notice this as dimmed lights will dim even more. What would fix this symptom?

Do I need to run a larger wire size? My pump is probably 150' from the holding tank.

On 2020-07-12 - by (mod) - detect problem of well running out of water

Probably not, Jose. I may have been hasty (trying to answer too many questions too fast - apologies). The symptom you describe occurs usually when there is low flow rate of water into the well combined with a pump protection switch or device (designed to shut off the pump to prevent it from running "dry" and thus being damaged). A diagnostic step is to stop using water for as long as you can - several hours or more - to let the well recover (if it can). IF then you find that the pump delivers water normally, the problem is probably poor or low flow rate. Let me know and we can take it from there.

On 2020-07-12 by Jose

Thanks for the response Dan. Could the problem be a leaky foot valve if the pump doesn’t lose prime? The pump is able to immediately pump water every time it turns on but it only stays on for a few seconds. This happens even if I’m holding the pressure control “fill” lever.

On 2020-07-11 - by (mod) - signs of a leaky foot valve

Jose The no. 1 most common cause of loss of water after a power loss, provided the well or electrical system didn't itself take a direct lighting strike, is that the well had a pre-existing leaky foot valve. During the power outage the pump lost prime as water drained back into the well. Try re-priming the pump, but ultimately you'll need to replace the leaky foot valve or other check valve in the system.

On 2020-07-11 by Jose

BTW, I forgot to add that when the pump shuts off after running for a few seconds it won’t run again until about 20-30 seconds later, even if manually holding the pressure switch “fill” lever

We had a storm a few days ago and lighting (sounded fairly close) that cut our power off until the utility company fixed things a few hours later. We continued using water while power was out but had no water pressure when power came back. I replaced the old pressure switch with a new one that has the little lever to manually switch on the pump to refill the tank when pressure drops too low.

The pump only runs for a few seconds and then shuts off. I have to manually hold lever (over and over) until I finally get enough pressure in the tank where the switch takes over, but even then the pump only runs in 2-5 second increments until it reaches max pressure (60 PSI). Pump is about 5 years old without problems prior to this. What could be causing this issue??

On 2020-06-25 - by (mod) - is the pump 120V or 240V?

Really The pump may be a 220V motor unit - do you know? Do you have the pump IO manual? Is there a data tag on the pump giving its brand and model?

Dave Two common causes of a circuit breaker tripping when the pump turns on are - a short circuit anywhere in the well pump wiring - those issues are discussed above on this page - a seized or frozen pump motor - details are at ELECTRIC MOTOR DIAGNOSTIC GUIDE inspectapedia.com/electric/Electric_Motor_Diagnosis.php but Watch out : if you're not familiar with safe electrical wiring and practices, don't fool with these tests yourself as you could be shocked or killed. Your electrician can do some simple tests, measuring resistance, to get a clue about what's happening. If the pump is a submersible unit, in the well, it may have to be pulled in any case, as the problem is either the wiring or the pump or its control switch.

On 2020-03-20 - by (mod) - What would cause a main power fault indicator on my main system board?

Stuart I can but make a feeble guess as you don't give the name of equipment, model no. etc. that would permit consulting the installation and operation manual for your well pump (or other equipment unspecified) But typically a power fault means low voltage or loss of voltage or, less likely, reversed polarity. Knowing the context is diagnostic: is this a new indication on equipment previously installed and working properly or has the indicator always been on since installation?

Wire fried on well pump. Water stopped working. Then wire sparked when turned back on. How can I fix it please?(far right wire see image) --> - Valerie

Moderator reply: burned wiring probably means shorted wires or damaged / failed water pump

The burned wiring tells us that there was (probably) a short circuit in the wiring and/or a seized pump motor.

It is of course unsafe.

I worry as well that no fuse blew nor circuit breaker tripped.

Do not just insulate and turn power back on.

Leave the circuit off to avoid a fire and shock hazard - sorry I know that's not exactly convenient.

Your repair tech or electrician will do some tests to find out if the problem is a seized pump motor or shorted wires - that's when we will know what repair is needed.

You will need at least a new pressure control switch (notice the overheated, burned contacts not just the wires), and perhaps some new wire and most trouble, perhaps a new pump).

If the pump motor is seized (or overheated and failed) that in turn can be caused by a variety of problems such as well running dry or pump running constantly.

Do keep me posted.

Reader follow-up: my pump was cycling on and off alot

Thank you so much for your quick response Daniel. My water pump cycles a lot.

Do you think the two are related. Over used/overworked system?

Just curious. Hope to have a specialist come out today. Will definitely keep you posted. Thanks again.

Moderator reply: pump short cycling can cause well pump damage and / or pressure switch burn-up

Yes - if you search InspectApedia.com with the on page search box you will find our articles on WATER PUMP SHORT CYCLING - home

Often the cause is a water-logged pressure tank.

But prolonged rapid on-off cycling might indeed burn up a pressure control switch. If that was the cause you will be so lucky because the fix is pretty easy and all above ground.

Replace the switch and any burned wiring and correct the air charge in your pressure tank.

On 2020-01-19 by (mod) - low-voltage problem at the well pump

Bobby That certainly sounds like a low-voltage problem. Often when a pump motor itself is failing it can draw high current and dim lights, but as you have a new pump I suspect the problem is in the wiring or panel or electrical service itself. An electrician would 1. check supply voltage right at the electrical panel

2. check every wiring connection for looseness, overheating, arcing, corrosion, etc.

3. check circuit fusing and wire sizes and lengths Watch out : if you are not trained in safe electrical work you could be shocked or killed. Don't fool with it.

On 2019-03-28 1 by (mod) - Where do the black and white wire go on a well pump?

Aaron I cannot bet your life or the fire-safety of your building by making a guess at exactly what wiring you're trying to connect - I've got just no information about what your pump and control wires are. Typically in electrical wiring Black = hot and White = neutral, particularly on 120VAC circuits. However if your pump is a 240V pump someone could have run a two wire circuit to it and both wires could be hot. So sorry but I can't give an answer to what wires go where on an unknown switch for an unknown pump. It's just too dangerous. Watch out : Please keep in mind that if you are not trained and familiar with proper and safe electrical wiring, making a mistake can kill someone or burn down the building.

Why would the wires in my well keep breaking

On 2019-01-17 by (mod) - testing a submersible pump

Yes, an experienced electrician or pump installer can get an idea if the pump motor is working properly by measuring its current draw when the pump is turned-on.

On 2019-01-17 by Ronnie Neathery is there any way I can test pump

I bought some new property that has a deep well pump which is 375' to 400', it is a old homestead when the previous owners left they cut all the wires in well casing and at concrete slab,why is beyond me.

It's 3 wire, is there any way I can test pump before I sink money in a control box,new wire and pressure tank or do I just need to pull pump and replace?

On 2019-11-08 by (mod) - why your well pump keeps tripping the circuit breaker:

Bush: Let's diagnose this problem of why your well pump keeps tripping the circuit breaker: 1. What is the ampacity or AMPS number on the circuit breaker? Is it 15A, 20A or something larger, and is the breaker a single pole (one switch 120V) or double pole (two switch 240V) 2. Now take a look at the data tag on your water pump; is the pump 120V or 240V (some pumps can be wire to either voltage so if that's the case, how is your pump wired? and what is the AMPS rating of the pump - from the data tag Now if the pump AMPS is greater than the circuit amps, that alone would trip the circuit breaker; 3. About the prior pump motor seizing: that may occur if the pump is allowed to run "dry" for an extended period; IN turn that would mean that your well is out of water or nearly out of water and has a terrible recovery rate. If that's the case then running out of water happens even faster with a new bigger more-powerful well pump; Now if the new pump includes a pump protection feature, that could be turning off the pump. SO unless there is a wiring or ampacity error you need a plumber or well service company to open the well and inspect its condition and its water level and perhaps its flow rate. In the ARTICLE INDEX you'll find articles on how to test the well's flow rate or recovery rate.

On 2019-11-08 by Bush

My pump seized. I was advised to buy a much bigger pump. Installed the bigger pump to my old motor both with 0.75kw.when I turn on power, it pumps water for 3minutes,then the relay switch breaks, it automatically turns on after a minute, then breaks again in 2minutes.is it a motor problem or I need a much bigger circuit break?

On 2019-02-25 by (mod) - we have no water

Ed You should find the pump circuit in the main electrical panel and follow it from there. There may be another switch right at the location of your water pressure tank and pump controller.

On 2019-01-05 - by (mod) - pump stops after just adding 2-3 psi to the pressure system

Anon When a pump stops after just adding 2-3 psi to the pressure system my first guess is that it is significantly mis-adjusted - perhaps on the differential screw or nut. But if you bought and installed a brand new 30/50 pressure controller And if you cleared or replaced the tubing or pipe that brings water pressure to the control from the pump or piping or tank, then yes, I'm stumped too. Can I assume that you've checked the water pressure with a reliable, independent pressure gauge to confirm that you're only seeing 2-3 psi? What happens if the pump is forced to keep running independently of the switch? If the pump can't develop more than 2-3 psi in that case there's either no water available or a gross water pipe leak or a pump that is itself damaged - say a bad impeller, low voltage, etc. Watch out : forcing the pump to run on without the pressure control is dangerous: if you exceed the tank and piping rated pressure you can blow out a pipe or tank, risking injury or death to anyone nearby as well as, of course, flooding the area. In sum I want enough diagnostic steps to figure out where the problem really lies: - in the pressure control switch - in the pump itself - in the piping - in the well's water level and flow rate - in an ancillary pump protection device

On 2018-12-24 by (mod) - only 120 V at a 240V pump hook-up

Darryl I'd like to help but am a bit scared of you getting electrocuted (killed) on Christmas Eve. If the pump uses 220 and only one line has power (120 or 110V) then the other line is open, and dangerous. If you can't find the break in the wiring it'd be safest to leave power off until you have an electrician on site. I'm not sure what the water valve switch is. The water pump ought to be completely independent from the septic lift pump.

On 2018-12-24 by Darryl

I have a 220 volt submersible pump for domestic water. It stopped working. Only 110 volt at the switch. Checking breaker, I have 220. However I noticed a wire labelled water valve switch inline with one leg of pump supply. It would appear this is open.

What is this water valve switch. Note , I have above ground septic bed with lift pump. Merry xmas. Help

On 2018-11-15 by (mod) - lost all water pressure, manually re-set the pump - repair people hot wired the pump and burned things up

That sounds as if a pump protection switch OR a circuit breaker was shutting off the pump circuit due to a problem that could be with the well itself (running out of water) or with the pump (drawing excessive current).

The bad news is that when keep forcing a pump to run when its protection equipment keeps turning it off, we risk creating a more-costly repair: the pump motor overheats and is damaged and perhaps ruined, or other pump parts like an impeller are ruined by running dry.

A pump can also be damaged if it's a 240 volt pump getting power on just one leg (120V) of the circuit - if you keep forcing it to "run".

Whoever was helping you was NOT in my OPINION the most-expert person in the box.

If a pump is damaged and won't run, replacing the water pressure tank won't fix the pump. So I'm thrilled that the onsite tech concluded "the water pressure tank was not the issue"

The technician was better than your first onsite guy in tracing the pump problem to a loss of power on one of the two 120V legs of what sounds like a 240V pump.

Now we read that there's a fuse panel problem that needs to be repaired

Watch out : that's an unsafe condition - you need help from a licensed electrician.

And yes, it sounds as if the pump may need to be replaced.

An experienced technician should know how to measure the current draw of the pump before pulling it out of the well - that can tell us if the pump is working properly or not.

Watch out : bypassing fuses or circuit breakers to "test" an electrical circuit is something that some nervy and in my OPINION under-trained service people might do, but in my view it's a serious error that risks starting a building fire or shocking somebody or worse.

So yeah, your pump people don't sound like they're innocent here, but unfortunately, you, as a "non-expert" probably had already damaged if not ruined your pump by continually forcing it to run when it was trying to shut itself off to avoid damage.

So you share some of the blame. The unfortunate compounding of trouble here is that the people you called

- went ahead with expensive repairs that were probably not needed

- caused additional damage that increases the total job cost

On 2018-11-15 by Brad

My well problems began with total loss of water throughout my home. We could regain functionality by manually resetting the switch. This lasted for about two days, and then we had to do it again. The third time it happened, we were unable to manually reset the switch. We are a family of four that scrapes by on my income.....

so, if manually resetting the switch gave us a temporary solution while trying to figure out a long term solution, that was our goal. So, we called a plumber out for an estimate. He immediately noticed we had a blown fuse in our service box.

He used a piece of wire to jump the blown fuse and we still had spark at the switch, but in his words, not enough voltage to actually turn the pump on because the wire was too small. So he surmised that the tank was bad and that was making the switch over work and that's why the fuse popped. He did no electrical testing before coming to this conclusion....

.the price he quoted was nearly $800.....we contacted some family members and scraped together enough to cover the repair. The tech came out the next day and upon looking over the situation determined that the tank was not the issue....

that it was probably something to do with the absence of a check valve, or the switch itself.....

again, with zero electrical testing.....he told me that he couldn't simply add a check valve to the existing system or simply replace the switch because the plumbing was in disrepair and he'd probably break some things off when trying to do those things......

since we had already secured the funds to cover the repair I decided that replacing the tank as well as all components involved was a good idea since everything would be new and would ease my mind that it was all set.

Plus, since the old tank was still holding air pressure I could maybe sell it for $100 or something. So the tech went about replacing the tank and all components. When finished, he tested it....

he told me all of the following only after he had finished.....

he was only getting half of the 240 volts necessary at the switch with both fuses in place....so he took both fuses out and hard wired the fuse box. After doing so, he turned the breaker back on and something popped in the fuse box leaving a scorch mark inside of the fuse box and at that point he determined that the pump wasn't running.....

so, essentially we paid them $800 for a repair that didn't fix the problem and now are saying that our pump is bad, that they will need to pull and replace it and that will cost me an additional $1000....

my questions are numerous....is hardwiring and bypassing fuses standard practice?

Could the electrical spike that popped inside the box and scorched it have also fried my pump? They are telling me that the event that happened in the fuse box would definitely not have burned up my pump....

but they have been wrong and or shifty in general the whole time....are they trying to get me to pay them more to fix a problem that they created? And was that problem created by them due to incompetence and unsafe practices?

I really don't know what to do and I would love some insight from a different source than the one who has misdiagnosed, potentially damaged my property, and denied wrongdoing at every turn. Thank you

And now I don’t have power from the breaker to the switch. It did get really wet out in my pump house do to burst pipe twice in the last 6 months. I changed the wire that runs from the breaker to the switch and the pump kicked on again but it shut off early again and now it reads dead again. I’m pulling my hair out please help

The new lines can be snaked through the larger diameter plastic line. But I can't know for sure what you've got with no other description than your note. Take a look at the fittings, wiring, and water piping involved.

Tom The situation you describe makes me nervous. A FRN type fuse is a delayed response fuse intended to tolerate a very brief moment of high current draw that some electrical equipment uses, like compressor motors or large milling machines. If you use a non FRN the fuse might indeed blow at equipment startup even if otherwise it could carry the running load of the equipment it serves. But when you get repeated fuse blows including the FRN-R-20 fuse that you moved to the troublemaking side of the panel it sounds to me as if there is a short or defect in the equipment. I would have left such equipment OFF, have an electrician inspect the equipment and measure its current draw for proper and safe operation before trying to get it going with the right time-delay fuses. A wrong fuse that is "wrong" only in missing a required time delay to tolerate a startup load might luckily (or because it's defective and unsafe) survive for a few motor starts in a panel. But that would not explain a pump motor that wouldn't start. What would explain it would be

- one side of a 240V circuit is dead or its fuse blown, so the pump is getting just half its voltage

- a seizing or failing pump motor

- a bad pump start/run capacitor

Could the wrong 20amp fuse keep the pressure switch from turning on the pump? I picked up the correct fuses today but I was just curious. Thoughts?

Why Does The Breaker On My Well Pump Keep Tripping?

One of the most common reasons why the breaker on your well pump might keep tripping is due to an overloaded circuit. This typically happens when too many devices or appliances are simultaneously drawing power from the same circuit. For instance, if your well pump shares a circuit with other high-powered appliances, the combined energy requirement may exceed the circuit’s capacity, causing the breaker to trip as a safety measure.

As the owner of Austin Drilling & Well Repair Inc, a licensed well pump repair company in Columbia, SC, I understand the importance of a reliable well pump for a consistent water supply. However, a tripping circuit breaker can disrupt your well’s performance, leaving you without water and in need of prompt solutions. In this comprehensive guide, we’ll explore common reasons why the breaker to your well pump may trip and offer practical tips to address the issue effectively.

Reason 1: Overloading of the Circuit An overloaded circuit is one of the most common reasons why the breaker to your well pump may trip. When the well pump draws more current than the circuit can handle, the breaker automatically shuts off the power to prevent electrical hazards.

Solution: Reduce the electrical load on the circuit by disconnecting or turning off any other electrical appliances or devices connected to the same circuit. Consider redistributing electrical loads across different circuits to ensure balanced power distribution.

Reason 2: Motor Issues Issues with the well pump motor can also lead to breaker tripping. Motor problems, such as a short circuit or damaged windings, can cause excessive current draw, triggering the breaker’s protection mechanism.

Solution: If you suspect motor issues, it’s best to seek professional assistance from Austin Drilling & Well Repair Inc. Our experienced well pump technicians can inspect and diagnose the motor for any damage or malfunction. Depending on the severity of the problem, we can recommend motor repairs or replacements.

Reason 3: Waterlogged Well Pump A waterlogged well pump is a common issue in wells with a submersible pump. When the pump’s motor becomes flooded with water, it can cause the breaker to trip due to electrical short circuits.

Solution: A waterlogged well pump requires immediate attention from a professional well contractor. Contact Austin Drilling & Well Repair Inc to inspect the well and determine the cause of the waterlogging. Proper sealing and wellhead maintenance can prevent this issue from recurring.

Reason 4: Faulty Wiring or Connections Loose or damaged wiring and connections within the well pump system can lead to increased resistance and heat buildup. This can trip the breaker as a protective measure.

Solution: Regularly inspect the wiring and connections of your well pump system. If you notice any loose or damaged components, contact Austin Drilling & Well Repair Inc to perform necessary repairs or replacements. Ensure all connections are securely tightened to prevent future issues.

Reason 5: Ground Faults Ground faults occur when an electrical current flows through an unintended path, bypassing the intended circuit. This can cause the breaker to trip.

Solution: Addressing ground faults requires expertise and specialized equipment.

Well Pump Overload Keeps Tripping

For situations where we need water from a certain elevation to another, well pumps come in quite handy. These devices can transport water through areas that would otherwise be difficult to guide. However, we may run into issues with a well pump, especially one where our well pump overload keeps tripping.

Why does my water pump keep tripping the breaker?

To run a water pump needs to have a constant influx of electricity. In a situation where that electricity is cut, the water pump will cease to function. While there are a lot of outside dangers that can come our way when electricity outages are concerned, the pump itself can cause them. This situation will most often occur when said pump trips the breaker. Why does this happen? Let’s find out.

The pump is leaking

If our water pump leaks, the cases where the breaker is tipped can easily happen. The leaks most frequently occur from cracks in our water pump’s housing. When the housing is cracked, we’ll see water seep through said cracks. Reach to the pump’s electrical part, causing a short circuit.

This is not only a distracting situation that can slow down any work we are doing at the moment but also a hazard. Not treating these situations could pose a significant electrical hazard to our household and us. Despite starting off as a simple case of circuit breaker tipping, it can swiftly evolve into far more, especially if the water pump is near other electrical devices.

There’s an overload in the system

Yet another reason we may see circuit breakers being tipped frequently is overcharge. The overcharge occurs in a situation where the pump is drawing more power than the breaker is capable of handling. As a result, the breaker will end up tipping in order to prevent an overwhelming amount of electricity from being pulled. [ 1 ]

While the larger water pumps will require that energy, we’ll need to replace the breaker to allow electricity to flow. The issue of overcharge can often be avoided by purchasing the correct pump in the first place or the right breaker. There shouldn’t be more energy than the breaker can handle flowing through the connection if we want to avoid the situation where tipping happens.

Clogged impeller

An important part of a pump is an impeller. An impeller works the opposite of a propeller. Sucking in items rather than releasing them. Its performance can, potentially, lead to clogs happening. A clogged impeller will affect the water pump.

Having it try to dislodge the clog by seeking more electrical energy and then tipping the breaker as a result. If this occurs, inspect the impeller and remove debris that may be stuck in. [ 2 ]

Pressure switch

The pressure switch may be the issue in some situations. The switch could be worn out or malfunctioning. If that’s the case we find ourselves in, we could end up having more power being drawn into the pump. That surge of energy will lead to the eventual tipping of the circuit breaker. Take proper care of the pressure switch and make sure to check on it eventually. [ 3 ]

Pump tripping problem

We should consider these potential issues to resolve issues of a pump tripping the breaker. Fixing them will usually lead to a functional well pump that doesn’t trip the breaker and operates without a hitch. However, it is possible to end up with more complex issues in which situation professionals should be called.

Well breaker trips intermittently

Well pumps are mandatory to manage and maintain our well’s water level . However, their utility is only functional in situations where our pumps aren’t overwhelmed by some problem or where the flow of electricity is constant. The easiest way our flow of electricity can be through our breaker being tripped. If this frequently happens and becomes intermittent, we will have to deal with it.

These occasional cuts to our power will cause multiple issues to the overall system. The first and most obvious is that our well pump will not function the whole time, rendering it useless.

When a pump is constantly stopped and started, its internal workings of it can get messed up. What’s supposed to be reliable will get fried by the constant off-and-on situation that breaker being tripped causes.

Pump overload causes

Some configurations and specifications are tied to the parts of our pump that can impact its functionality too. The overload these can cause is dangerous, both as a hazard and as a danger to our pump.

Oversized impeller

An oversized impeller can be one such issue. The impeller will draw far more power which can be a quick way to end up overloading our pump. In situations such as this, we need to replace the impeller.

Additionally, this is a great reminder to consider your purchase. Do not buy overly powerful pump parts without being sure they can be accommodated.

Worn out parts

Another source of overcharge could stem simply from the pump being worn out or damaged. This is cause similar to that of standard cracks and leaks that may occur but usually assume age to be a factor too. In this situation, having consistent maintenance can prevent the problem before it happens.

Bad installation

Misalignment between the parts of the pump and the connections to the grid. When the installation of our pump isn’t properly done, we will frequently experience issues. One of these issues is overloading. It’s important to maintain the proper installation process to guarantee success. [ 4 ]

Well pump thermal overload

With pumps, we need protection from the potential electrical systems being shorted. One of the types of protection is thermal overload. Unfortunately, the thermal overload protection used on smaller pump motors often isn’t the best source of protection.

This malfunction of the thermal overload will often happen as a cause of other heat sources. Additionally, the sunlight could damage the pump likewise. Therefore, protecting the pump is key, whether from the sun or other sources of heat.

New well pump tripping breaker

A new well pump can cause issues with our circuit breaker the same way an old one can. However, the issues with the pump may stem from more than just our standard array of wear and tear or problematic parts. The new pump can suffer from an issue all on its own.

The most frequent problem we may face is simply that the item doesn’t fit with our electrical energy’s capacity. For example, we may have a pump that’s too powerful or doesn’t have all the required failsafe, leading to far more problems with said pump. This requires some extra inspection and planning when buying the pump to avoid.

What causes well pump to trip the breaker?

While we’ve seen what causes we may have for our well pump causing the problems, a few more should be considered. These problems can be as simple as incompatible parts or as complex as a major electrical malfunction.

Well Pump Motor

We can expect quite a few other issues with well pump motor malfunctioning. The problems are quickly going to crop up because electrical components can get quickly damaged by water.

Rodent or Pest Problem

The problem of small animals such as rats and cockroaches infesting our home can be extremely problematic. This is exceptionally troublesome for sump pumps as the pest can damage many pump parts. Additionally, pest infestations can damage our wiring, which can cause the breaker to trip. [ 5 ]

Well pump overload keeps tripping

When the issue persists, it’s usually best to get a detailed inspection of our system. Calling a professional to do a check on both electrical installation and our well pump is a good way to guarantee any outlying issues will be found. The problems could affect other devices without proper repairs, so getting a check done is universally useful.

Well pumps are useful and, in some cases, key parts of transporting water from one area to the other. They are built to last and offer a simple operating procedure to boot. However, we could likely end up with a problem that affects the pump negatively.

To resolve the issue of breaker tripping, we should check all the potential causes of the problem. Additionally, monitoring the pump’s functionality can reassure us whether the problem we resolved was the only one. If it isn’t, and if none of the more basic malfunctions are to blame, professionals should be called in.

• Why Does My Well Pump Trip The Breaker?

If you have a well pump that keeps tripping the breaker, it can be a frustrating and inconvenient problem. When your well pump trips the breaker, it means that there is an issue causing the circuit to overload and the breaker to shut off the power supply. This can happen for several reasons, and it is important to identify the cause in order to fix the problem and prevent further issues in the future.

1. Overloading the Circuit

One common reason why a well pump may trip the breaker is that the circuit is being overloaded. This can happen if the well pump is drawing too much power, causing the breaker to shut off in order to prevent the wiring from overheating and potentially causing a fire. This can be caused by a malfunction in the well pump itself, such as a failing motor or a clogged filter that is causing the pump to work harder than usual. It can also be caused by other devices or appliances on the same circuit drawing too much power, such as a water heater or a sump pump.

2. Electrical Issues

Another common reason for a well pump to trip the breaker is due to electrical issues within the system. This can be caused by a short circuit, a ground fault, or a faulty electrical connection. When there is a short circuit, it means that there is a direct connection between the hot and neutral wires, causing a surge of electricity that can trip the breaker. A ground fault occurs when there is a connection between the hot wire and a ground wire, causing the electricity to flow through the ground instead of the intended circuit. A faulty electrical connection can also cause problems, such as loose or corroded wires, which can lead to overheating and tripping the breaker.

3. Motor Issues

If the well pump is experiencing motor issues, it can also cause the breaker to trip. This can be caused by a failing motor that is drawing more power than it should, or by a motor that is overheating due to a lack of lubrication or proper maintenance. When the motor is not functioning properly, it can cause the circuit to overload and trip the breaker in order to prevent damage to the pump or the wiring.

4. Well Pump Size

The size of the well pump can also play a role in whether or not it trips the breaker. If the pump is too large for the well or is operating at a higher pressure than it was designed for, it can draw more power than the circuit can handle, causing the breaker to trip. It is important to make sure that the well pump is properly sized for the well and that it is operating within the recommended pressure range in order to prevent overloading the circuit.

5. Age and Wear

Over time, well pumps can experience wear and tear that can lead to issues with tripping the breaker. As pumps age, components can wear out or become damaged, causing them to draw more power or malfunction in a way that can trip the breaker. Regular maintenance and inspections can help identify any potential issues before they become a problem and prevent the well pump from tripping the breaker.

In conclusion, there are several reasons why a well pump may trip the breaker, including overloading the circuit, electrical issues, motor problems, well pump size, and age and wear. It is important to identify the cause of the problem in order to fix it and prevent further issues in the future. Regular maintenance and inspections can help prevent well pump problems and ensure that your system is functioning properly. If you are experiencing issues with your well pump tripping the breaker, it is important to contact a water well professional to diagnose and repair the problem. By addressing the issue promptly, you can prevent further damage and ensure that your well pump is operating safely and efficiently.

When running water for an extended period of time, does the pump cycle on and off every few minutes or does it run continuously at low pressure?  

Reach4, it is on a 2-pole (I think that's what you call them) 50 amp breaker--two 25s that are "connected" together so it is one switch. Valveman, that is a great question. I am embarrassed to say I don't know. How do I tell when the pump is running? That seems like such a stupid question. I'm ashamed for myself. LOL  

Interesting about the breaker. I always figured more was better so I never thought you could have one that was too large. I will look at having that swapped out. That would be awesome if that was the fix. I'm currently having visions of needing a new well pump--something that I would imagine is not going to be cheap on a 400+ foot well! Now that you've explained how (and I thank you for that!) I will investigate how the pump is running. Possible the pressure tank is bad? I do notice that when I fill the washing machine in the basement that the water pressure to drop throughout the house. Could that be a sign of a bad pressure tank or just part of living on a well? This stuff is all new to me...  

A breaker won't blow because it is too large. However 50 amp breaker blowing without something smoking (exaggerating a bit) is suspect. I also hope the only problem is the breaker. The pressure drop when you fill the washing machine is unusual. Most washing machines don't draw water so fast. A clogged or under-sized whole-house filter could cause such a symptom of the whole house pressure dropping when filling the washer. Look at the pressure gauge at the pressure tank while filling the washer. I expect it to not instantly drop during such a load. You can troubleshoot that problem after you get the first problem resolved.

Back the the breaker--I misread your previous post and I think I'm misunderstanding the breakers. It is not a 2-pole 50 amp. It is a 2-pole with each switch labeled 25 amp--like the picture you posted above only 25 on the labels instead of 50. So perhaps the breaker is about right then as a 2-pole 25 amp? As for the pressure drop, I wouldn't be surprised if the whole-house filter is undersized. To me it looks tiny--smaller than a soda can. The only whole-house filters I've seen before have been those big canister ones that have the special wrench thingie to pry them apart. Thanks for the tip about checking the pressure gauge when filling the washer. I will do that. Breaker issue is definitely the priority though!  

If the pump is running continuously when the breaker trips, it is most likely a motor or wire problem. If the pump is cycling on and off every few seconds or minutes while you are using water for extended periods of time, the cycling has probably already damaged the motor. The sooner you stop the pump from cycling the better. You might get lucky and have a bad starting capacitor or even the breakers could be bad. You could stick in a new pair of 30’s and see what happens.  

1. I would check the wire size at the pressure switch. If it is #14 or #12, that is what I would expect with a 3/4 HP 240 V pump. If the wire is bigger, then I suspect your pump may be bigger than 3/4 HP. How old is your pump and controller? You may see a number printed on the wire, even if you don't know wire sizes by looking. Don't touch. Just look, after you pull the cover. Put the cover back on then. 2. Valveman suspects that it is possible that the pump is not restarting all of the time. Watching the pressure gauge during one of your big fills that pops a breaker could show that. Replacing the capacitor in the controller is not so expensive either. More expensive than a breaker, but still fairly cheap. Since you are not wanting to repeat your test too often, maybe you could record the pressure gauge by shooting a movie with a camera, evn the one on your smart phone, so that you could review the event. If during the movie, the pump goes on and off a few times, that could point to a problem and solution. There are more troubleshooting things that could be checked.  

Checked the wire, it is #12. I don't know how old the pump is. The house itself was built in 1989 and we just bought it about six months ago. I'm looking at the controller and it lists a model of Goulds pump that was available in its 2009 product catalog (came up when I Googled) so maybe not that old? However, maybe they same model pump is available today that was available 20 years ago. I don't know how that works. I suppose it's also possible the controller is new but the pump isn't? I may pop the cover on the controller and just see if there is any evidence of the capacitor being bad. I've read that sometime they leak a tar type substance when they go bad? I am guessing around $2-3,000 to replace the pump, so I'm all in for replacing the breaker/capacitor/controller! Of course they way things usually work for me is all that stuff is replaced and I still end up spending $3k.  

In the Trades

$3000.00 sounds like a lot, but when you factor in the amount of water that $3000.00 investment will give you, the water is damn near free.

A 3/4 HP motor should not require 25 Amps or even close to that at 230V. Why would you want to up the breaker to 30 amps ? 5750 Watts should make something smoke on the well motor controller, if it is drawing 25 amps. Chance is that there is something else on that circuit, Maybe a pool filter pump, or air conditioner, Water Heater ?  

My book shows a 25 amp breaker is the right one to use for a 3/4HP. I would use a 30 anyway, because there is usually a light or something else tied in.

I agree with you, but that is what the book says. Deadheading would actually drop the amps by about 50%.

4 Reasons Why Your Submersible Pump Might Be Tripping Its Circuit Breaker

Submersible pumps are a vital piece of kit for many industries and on many sites. This means that a pump which keeps tripping its circuit breaker is extremely frustrating. Not only does it impact on your workflow, but it also usually includes costly downtime too.

If you are wondering why submersible pump trip situations keep occurring on your site, you are not alone. But what are the 4 main reasons for them?

One common cause of a submersible pump tripping its breaker can be cracks or leaks in the housing. If your pump's housing is cracked, water could be getting into the pump through these cracks and causing it to short circuit. The same can be happening if you have a leak in your pump which is letting water in.

Another reason a submersible pump tripping circuit breaker event may happen is potential overload. But what does this mean? In simple terms, if your pump is drawing down more current than the breaker has capacity for, then it could cause it to trip out. Essentially, the breaker is doing its job as it detects that too much current is being drawn than it can safely handle.

Failed Seals

The next reason your pump could be tripping its breaker lies in failed mechanical seals. If the seals are perished or loose, then water can make its way into the pump windings. This will cause the breaker to trip until the seal is fixed. You may also find that a worn bearing could be the problem. This may cause the pump shaft to seize and mean that the starting current gets too high for your circuit breaker to handle.

Clogged Impeller

The impeller is a major part of any pump. A clogged impeller, however, will trip out your circuit breaker until it is cleared. Resolving this could be as simple as clearing debris which is clogging the impeller.

• Understanding Water Pump Breakers

Before diving into the causes and solutions for a tripping water pump breaker, it’s important to have a clear understanding of what a water pump breaker is and how it functions. A water pump breaker is a device that protects the pump motor from electrical damage by interrupting the flow of electricity when it detects an overload or fault in the system.

Within the breaker, there are several key components that work together to ensure the proper functioning of the water pump system. The main component is the circuit breaker itself, which is typically housed in a panel box near the pump. This breaker acts as a switch that can be manually turned on or off to control the flow of electricity to the motor.

When the water pump system is functioning normally, the circuit breaker allows electrical current to flow to the motor, powering it and allowing it to pump water. However, if the system experiences an electrical overload or fault, the breaker quickly detects this and trips, cutting off the flow of electricity to the motor to prevent damage.

Inside the breaker, there is a bimetallic strip or an electronic sensor that is designed to detect excessive current flow. When this strip or sensor detects a high current, it triggers a mechanism that physically disconnects the circuit, interrupting the flow of electricity. This action prevents the motor from drawing too much power and overheating, protecting it from damage.

Once the breaker trips, it needs to be manually reset by switching it off and then back on. This ensures that the system is safe and ready to be used again. It’s important to note that if the breaker continues to trip even after being reset, there is a deeper issue within the system that needs to be addressed.

Understanding the working mechanism of a water pump breaker is crucial in troubleshooting and resolving any tripping issues. By comprehending its function and the purpose it serves in protecting the pump motor, you can effectively identify and resolve the underlying problems that cause the breaker to trip.

• Common Causes of Water Pump Breaker Tripping

A tripping water pump breaker can be a frustrating and inconvenient issue to deal with. In order to effectively troubleshoot and resolve the problem, it’s important to understand the common causes behind the breaker tripping. Here are some of the most common causes:

• Electrical overload: One of the primary reasons for a water pump breaker to trip is an electrical overload. This occurs when the pump motor draws more current than the breaker is designed to handle. It can happen due to various factors such as running multiple appliances simultaneously, a malfunctioning motor, or a sudden increase in water demand. To resolve this issue, it may be necessary to reduce electrical load, upgrade the breaker, or consult an electrician.
• Faulty wiring or connections: Another common cause of breaker tripping is faulty wiring or connections. Over time, wires can become loose, damaged, or corroded, leading to poor electrical conductivity and potential short circuits. If the breaker senses an abnormal flow of electricity caused by faulty wiring, it will trip to prevent further damage. It is crucial to inspect and repair any faulty wiring or connections to resolve this issue.
• Motor malfunction: A malfunctioning pump motor can also cause the breaker to trip. Issues such as overheating, worn-out bearings, or a seized motor can result in excessive current draw, triggering the breaker. Regular maintenance and servicing of the motor can help identify and address any motor-related problems to prevent future breaker tripping.
• Low voltage or power fluctuations: In some cases, low voltage or power fluctuations in the electrical supply can lead to breaker tripping. Fluctuations in voltage can stress the motor and cause it to draw more current than usual, prompting the breaker to trip. Installing a voltage stabilizer or surge protector can help regulate the power supply and prevent such tripping issues.
• Pump or system defects: Lastly, defects in the water pump or the entire system can contribute to breaker tripping. Issues such as clogged intake filters, damaged impellers, or malfunctioning pressure switches can cause the pump to work harder, leading to increased power consumption and eventual breaker tripping. Regular maintenance and inspection of the pump and system components are essential to identify and rectify such defects.

By understanding these common causes of water pump breaker tripping, you can effectively diagnose the issue and take appropriate measures to resolve it. Whether it’s addressing electrical overload, fixing faulty wiring, servicing the motor, stabilizing the voltage, or repairing pump defects, identifying the root cause is crucial in ensuring optimal performance and avoiding future breaker tripping incidents.

What if the manufacturer supplies no clear information , how to size a circuit breaker for a pump, why is it important to choose the correct size breaker for a well pump, why it’s ideal to stick to manufacturer requirements .

Well pumps, especially submersible pumps, are not your standard motors and often require specialized overload protection. Just ask a lot of well pump installers in your area, and they’ll likely say they consult manuals such as this one created by Franklin.

It provides detailed instructions not only on breaker sizing and wire sizing but also considers distance, temperature, connection type (whether it’s single-phase or three-phase), starting amperage, and voltage drop. Even if we compare these tables to the one recommended by the NEC, you’ll see that they don’t really depart that much and even make it clear that they use its guidelines as a reference.

Let’s assume you use a 1.5 HP pump with a single-phase motor. Based on Table 14 in the Franklin manual and since you’re likely asking about the breaker size for the 230v well pump, you’ll need to use a 30 amp circuit breaker for it, not considering the distance. On the other hand, a 3/4 hp pump with the same motor type and voltage needs a 20 amp breaker. 

If you refer to Table 11 of the same manual that gives the maximum length of wire you can use to keep voltage drop under 5%, you’ll either need to use a 14 AWG copper wire or a 12 gauge one if your distance is either 190 or 310 feet, respectively.

Obviously, wire size should always be in sync with breaker size, and the Code usually doesn’t provide detailed breakdowns of these, unlike the tables found in these manuals. This underlines their value and why some installers make a beeline for them instead of NEC tables for motor amperage and wire sizes.

More importantly, it also accounts for the starting amperages of the pumps, which are usually high. For example, a 2 HP 230v single-phase pump may surge between 50 to 60 amps. Even if it lasts for only a few seconds, your breaker will still need to be able to handle that.

If you’re going to limit your references to passages in the Code, it’s still relatively safe, though, as proven by the next section.

Then always make sure that you size a breaker according to Code. Code rules are safe because they actually recommend the maximum, safest size you can use, meaning you can still settle for a smaller breaker without necessarily veering off the official guidelines.

If you’re not sure that you’re doing it properly, then just consult an inspector. In my experience, they always know how to provide accurate well pump electrical requirements while making sure your setup is perfectly Code-compliant.

Usually, residential well pumps have horsepowers that range between ½ HP to 2 HP. According to Code, for 1 HP well pump that’s 230V and single-phase, you may need to use a 25 amp breaker, for example.

But it’s rarely that simple. Well pump breaker size tends to be more range based on my experience installing well pumps.

These are the most important passages in the Code that are pivotal for determining the correct size circuit breaker with regard to well pump amperage. If you have a copy of the National Electric Code, it’s worth checking them out to see for yourself.

• 6(A)(1) makes it clear that you shouldn’t rely on the nameplate value but on the recommendations given in section 430.248, especially if the pump runs on a common single-phase motor.
• 52(C)(1) states that you should opt for the next breaker size if the total amp’s value does not correspond to the ones stated in section 430.52.
• That same section (430.52) provides a passage that underscores that a basic circuit breaker should not exceed 250% of the values shown in 430.248.

These facts prove that the Code recommends maximum size requirements, instead of minimum. This also proves that slight deviations from recommended values are fine as long as you remain compliant with these specific passages. 

Let’s start with this specific example. How many amps does a 3HP 230v single-phase well pump motor have? 17 amps.

Based on the 250% allowance said above, we’ll arrive at the following formula to get the maximum, safest breaker size for that specific pump:

17 x 2.5 = 42.5 amps

Typically, there are no breakers with that specific size. So we go to the next higher standard size, which is 45 amps.

Does that mean that you should limit yourself to that? As most inspectors will say, not really. They’ll likely size a smaller breaker that will still manage to start the pump’s motor.

In this case, if a 30-amp breaker can handle it, then it’s still perfectly code-compliant. The same goes for 35, 40, or 45-amp ones. However, anything beyond that is no longer technically legal.

Take note that these values don’t consider other factors like wire size and distance, like the ones expounded on above.

Submersible well pumps typically have high currents required to start properly. Obviously, your breaker and its corresponding wire conductor should be able to handle that or you risk the possibility of a fire.

Secondly, the pump won’t run optimally and may end up frequently tripping the breaker. Moreover, deep well pumps need to consider longer distances. There are a lot more variables, in short, compared to other gadgets and appliances.

So, again, to know what size breaker for a well pump, don’t depart from the instruction manual as much as possible, especially if the manufacturer already provides detailed information about it. If there are none, make your calculations based on Code rules—all the better if you have time to compare the two and confirm your findings.

If you’re still having doubts, don’t hesitate to ask for technical assistance from the brand you bought the well pump from or a certified inspector or electrician.

Question: The circuit breaker or fuses on a circulator pump have tripped. What might be the cause?

Circuit breakers and fuses trip for numerous reasons: undervoltage, incorrectly designed circuit breaker or fuses, too low a setting for the motor-protective circuit breaker, asymmetric three-phase current, a short circuit on the motor, incorrect wiring or faulty electrical connections, a worn or blocked pump, a defective capacitor for single-phase motors, a motor-protective circuit breaker exposed to a higher ambient temperature than the motor.

However, the pump may also be undersized for the application in question, and may be operating in excess of its nominal flow rate.

How to Fix a Breaker That Keeps Tripping

"Ok, where's the flashlight?"

We've all had to deal with tripped circuit breakers . They're annoying and happen at the worst times. As a licensed electrician, I've seen my fair share of breakers, tripped or otherwise.

Circuit breakers monitor the flow of electricity through a circuit. If it exceeds a preset amount, it opens the circuit to stop the current flow. They're a vital piece of your home's electrical system. And when they trip, they're trying to tell you something.

Occasional trips are not something to be alarmed about. But if a circuit breaker in your home keeps tripping, it could be a sign something's wrong.

How To Know if Your Circuit Breaker Is Tripping

If your breaker trips, go to your electrical panel and open the front cover. There should be two columns of circuit breakers and, hopefully, nice labels indicating what circuits each one controls. Most breakers will be on, so look for the one with the handle in a different position than the others.

On every breaker, there will be an "On" and "Off" position. On a tripped breaker, the handle will be in the middle, neither On nor Off. To reset, flip the handle to Off first, then to On. Stand to the side of the panel and turn your face away when flipping breakers. If an arc flash occurs, it may save your life.

Why Does My Circuit Breaker Keep Tripping?

Circuit breakers trip when too much electricity flows through the breaker. Circuit breakers are rated based on how much electricity can safely flow through the electrical circuit they're protecting. When that's exceeded, the breakers trip. A 20-amp breaker trips when more than 20 amps of current is on the circuit.

Circuit breakers trip for three main reasons:

• Short circuits;
• Ground faults.

What Is a Circuit Overload?

An overloaded circuit has too many things running on it at once.

Imagine a kitchen with a microwave and an air fryer next to each other. Kitchen small appliance circuits are 20 amps. A 1,200-watt microwave draws 10 amps. A 1,700-watt air fryer draws about 14 amps. Running both appliances at the same time puts 24 amps on a circuit designed for 20 amps.

Over time, those extra amps will damage the wires by generating excessive heat. A circuit breaker stops this overload condition by opening the circuit.

What Is a Short Circuit?

A short circuit happens when a hot wire comes in contact with another hot wire, or the neutral or ground. When a circuit operates normally, current flows on the hot wire from your electrical panel to a light, appliance or other load. Then it goes back to the panel via the neutral.

If the hot and neutral accidentally touch each other, the current takes a "shortcut" back to the panel instead of going to the load. The electricity generated by this contact is many times higher than if it was being used by a light or appliance. It's an extremely dangerous situation that can cause shocks and fires.

What Is a Ground Fault?

A ground fault is a type of short circuit. Ground faults happen when a hot wire touches a non-current carrying part of the electrical circuit, like a metal box or pipe. It's important for that unintentional, really high current to have a place to go, so non-current-carrying parts of your home's electrical system are bonded together and connected to a ground.

If there's no purposeful path to channel that ground fault current safely, it will go through anything available, including you. Ground-fault circuit interrupters (GFCI) are specifically designed to monitor for ground faults, but regular circuit breakers also provide protection.

How To Fix a Circuit Breaker That Keeps Tripping

If your breaker keeps tripping, investigate and fix the problem. Here are a few ways to narrow down the possibilities. Always call a licensed electrician if the issue becomes too involved.

Check for overload

Figure out which area of the house the tripped breaker controls, then turn off and unplug everything in that area. Lights, microwaves, computers, everything. Then go turn on the breaker. If the breaker trips immediately, even with nothing plugged in, it's likely you have a short, not an overload.

If the breaker holds, go back to the room and start plugging things in and turning them on one by one. After each item, pause, then do the next one. When the breaker trips again, you know you've reached your limit for that circuit. Redistribute the loads more evenly between circuits if possible.

Check for a short in a specific appliance

Shorts and ground faults can occur within an appliance or other electrical device when a hot wire touches the housing.

Note the last thing you plugged in when the breaker tripped while checking for an overload. If you plug that appliance or device into another circuit, does that circuit trip as well? If so, unplug the device immediately and don't use it until it's replaced or serviced.

Call an electrician for shorts and ground faults in the wiring

If the breaker trips immediately upon resetting, even with nothing plugged in or turned on, it's likely something in your home's wiring causing the problem. This could be a loose connection at a receptacle or other device, or something more complicated, like worn insulation within your walls.

If you have electrical experience and can determine which device is causing the short, replace the device or correct the loose wire. If you're not experienced, or you smell something burning or see scorch marks on your walls, call a professional licensed electrician. Do the same if you have repeated problems with flickering lights or tripping breakers.

Electrical fires and shocks are dangerous, and shorts and ground faults are difficult to find. A pro can diagnose and fix the issue, providing peace of mind.
