15 Or 20 Amp GFCI(Difference, Use, Pros & Cons)

Do you need a GFCI receptacle for your home? If you do, what is the appropriate amperage to get? Does it make sense to add a 20-amp GFCI to a 15-amp circuit? What about a 15-amp GFCI on a 20-amp circuit? What would happen if you got that decision wrong?

How Do I Know If I Need A 15 Amp or 20 Amp GFCI?

For many people, their selection of a GFCI is determined by the types of devices and appliances they want to operate. They are convinced that the amperage of the GFCI has to match the total amperage of the devices that GFCI will operate.

For people with this mindset, a method that can determine whether the total draw of all your appliances matches the amp rating of the GFCI:

1). Find The Wattage

You have to start by calculating the amount of electricity your appliances will use if you connect them all to the same GFCI. This creates a problem. Many appliances are rated in watts.

You cannot compare the wattage rating of your appliances to the amp rating of a GFCI. Fortunately, this problem has a solution.

Start by adding up the wattage of all your appliances. Record the total on a piece of paper so you don’t forget it.

• How Many Watts Can An Outlet Handle?

2). Take The Amperage Rating

Now that you know the total wattage of your appliances, you can turn your attention to the GFCI. Take the amperage rating of the GFCI and multiply it by the voltage of your power supply.

For instance, American households use 120V power supplies.

If you have a 15A GFCI, multiply 15 by 120V. This will give you 1800W.

1800W is the total number of watts the breaker can tolerate. But it isn’t the total number of watts you can use.

The NEC expects consumers to use only 80 percent of the maximum allowable wattage. In this case, 80 percent of 1800W is 1,440W.

3). Compare The Total Wattage With The GFCI

1,440W is your target.

The total wattage of all the appliances that the GFCI will support cannot exceed 1,440. If the total wattage of the appliances is greater than 1,440W, you need a new GFCI breaker with a superior amperage.

This method prevents you from installing a GFCI of the wrong amperage.

But what if you don’t want to do these calculations? What if you cannot figure out the total wattage of all your home’s appliances and devices?

Well, you have a simpler solution. At the end of the day, GFCI receptacles are expected to act as a replacement for your ordinary outlets. This means that the capacity of a GFCI receptacle has to match the capacity of the ordinary outlet it will replace.

The rules governing the selection and installation of ordinary outlets are surprisingly straightforward:

The Selection And Installation Of Ordinary Outlets

1). circuit rating.

Most homes in the United States use 15 and 20A circuits. The chances of finding a 30 or 40A circuit in a residential setting are very low. Habitable homes do not require that much power.

Any calculations you have to do with regards to selecting a GFCI of the right amp rating will revolve around a 15 or 20A circuit.

2). GFCI Rating

The amp rating of an outlet has to match the amp rating of a circuit. In other words, if you have a 15A circuit, you should install 15A outlets. If you have a 20A circuit, you should install 20A outlets.

Can you install a 15A outlet on a 20A circuit ?

Yes, you can. The rating of an outlet can be equal to or less than the rating of a circuit. But the rating of an outlet cannot exceed the rating of the circuit to which it is attached. Therefore, 15 or 20A outlets are compatible with a 20A circuit.

You cannot add a 20A outlet to a 15A circuit. The practice is dangerous because it allows the outlet to transmit more electricity than the circuit can handle. In the best-case scenario, a 20A outlet will cause the 15A circuit breaker to trip. In the worst-case scenario, the breaker will fail to respond and a fire will start.

These same considerations apply to GFCI receptacles, which is why I expect consumers to install 15 or 20A GFCIs on a 20A circuit and 15A GFCIs on a 15A circuit.

Do not attach 20A GFCIs to 15A circuits.

3). Finding The Rating

If you installed the original outlets, the GFCIs won’t present a challenge because you can just apply the same logic you used when you installed those original outlets.

If you did not install the original outlets but you want to add the GFCIs yourself, try to match the rating of the GFCI to the rating of the outlet.

For instance, if you want to replace a 20A outlet with a GFCI, make sure you use a 20A GFCI as well. If the outlet has a 15A rating, use a 15A GFCI.

If you don’t know the rating of your outlets, you can find out in two ways:

• Outlet – Check the outlet . Some outlets have labels that clearly reveal the rating.
• Breaker – Go to the electrical panel and find the breaker that feeds the outlet. The breaker is also marked. To find the breaker that feeds the outlet, plug a light into the outlet and switch it on. Start flipping the breakers off one at a time. The right breaker will cause the light to go off. Mark it with tape and take note of the amp rating. That is the rating your GFCI should have.

What is the Difference Between 15 Amp and 20-Amp GFCIs?

15 amp and 20-amp GFCIs are not the same. They have various differences that affect the work they do, for instance:

1). 20A Have T-Shaped Neutral

You won’t have any trouble differentiating between 15 and 20A GFCIs because they don’t have the same design. Just like ordinary outlets, 15 and 20A GFCIs have three slots.

They are designed to accommodate 3-prong plugs . 20A outlet has a T-shaped prong. This is neutral.

A 15A receptacle does not have a T-shaped neutral.

20A plugs can only enter 20A outlets. This applies to 15A outlets as well.

Many people look at the labels that accompany their appliances to determine whether or not they require a 15A or 20A circuit.

But in many cases, if you look at the plug of the appliance, it will show you the type of outlet it requires. This, in turn, will help you identify the right circuit for the appliance.

2). 20A Is Used For Heavy Duty Appliance

20-amp outlets can transmit more power than 15-amp outlets. Therefore, 20-amp outlets must be installed in places like the kitchen, bathroom, and laundry room that normally house heavy-duty items like washing machines, hairdryers, and microwave ovens.

You don’t have a choice in the matter. The regulations governing electrical installations in most places expect homeowners to use 20A outlets in the kitchen because they contain appliances that consume a lot of power.

Therefore, you need 20A GFCIs in the kitchen, bathroom, laundry room, garage , and any other location with heavy-duty appliances.

You can use 15A outlets in every other location. They are commonly used for lighting purposes. Places that require 15A outlets should be used to accommodate 15A GFCIs.

You shouldn’t install a 15A GFCI in the kitchen when kitchens clearly require 20A receptacles. On the other hand, you are free to add 20A receptacles to places that require 15A outlets. There is no downside to this practice.

3). 20A Is Costlier

Many homes use 15A outlets because they are cheaper than their 20A counterparts. This is true for GFCIs as well. However, the difference in cost is small. In the long run, it shouldn’t impact your decision to use either 15 or 20A GFCIs.

4). You Can Plug 15A And 20A GFCI To 20A Circuit

You can connect both 15A and 20A GFCIs to 20A circuits. But you can only connect a 20A GFCI to a 20A circuit. A 20A GFCI on a 15A circuit is inappropriate and dangerous.

5). You Can Use 14 Gauge Wire For 15A While 12 Gauge For 20A

With 15A circuits, you need a 14-gauge wire. 20A circuits, on the other hand, should be paired with 12-gauge wire. You can use a 10-gauge wire or even higher if the wires have to cover a large distance.

The difference in the gauge makes sense. A 20A GFCI is designed to transmit more power than a 15A GFCI. Therefore, it requires larger and thicker wires.

Can I Use 15 Amp GFCI On 20 Amp Circuit?

The NEC prohibits people from installing outlets that exceed the rating of their circuits. A 15A GFCI can run on a 20A circuit because it has lower power requirements than the circuit’s rating. It is less likely to overwhelm the circuit.

Can I Use 20-Amp GFCI On 15 Amp Circuit?

You can’t use 20A GFCI on a 15A circuit because a 20A GFCI will draw more power than the 15A circuit can handle. This will cause the breaker to trip. If the breaker malfunctions, you could start a fire, especially if you are using that 20A GFCI to operate a 20A appliance.

15A GFCI Pros & Cons

• They are slightly cheaper than 20A GFCIs
• Most devices in a home can run on 15A GFCIs
• Easy to find
• They rely on 15A circuits which use cheaper 14-gauge wire (in comparison to the 12-gauge wire that 20A circuits use)
• You can add them to 20A circuits
• They cannot run heavy-duty appliances
• The NEC prohibits you from installing them in locations like the kitchen and bathroom

20A GFCI Pros & Cons

• They can run heavy-duty appliances
• They can transmit more power
• You can connect more devices and appliances to a 20A GFCI
• They are more expensive than 15A GFCIs
• Their circuits require 12-gauge wire or higher which is more expensive than the 14-gauge wire that 15A circuits use
• They require a specific type of plug with a prong that can fit in the T-shaped neutral of a 20A outlet
• You can’t add them to 15A circuits

What Amp GFCI Should Be Used in Bathroom, Kitchen, Garage?

You have to add GFCIs to any space that exposes the outlets in the vicinity to moisture. That includes the bathroom, kitchen, and even garages.

Though, the NEC only expects to see GFCIs in grade level or below grade level garages that are not meant to act as habitable rooms. You also need AFCI protection on 15 and 20A circuits.

But what is the appropriate rating for a GFCI in these locations? You need 20A receptacles.

They transmit more power, which means that they can operate heavy-duty appliances like microwaves and freezers.

You don’t have freezers and microwaves in the garage. But you probably have workstations with drills, compressors, and other power tools. Naturally, these require 20A circuits, outlets, and GFCIs.

Bathrooms are in a similar boat. If you want to run your hairdryer safely, you need a 20A circuit and outlet.

You could experiment with 15A GFCIs in these locations if you do not have a choice. However, doing so would contravene the regulations of the NEC. Unless your local code says otherwise, the NEC wants 20A outlets to support the kitchen countertop.

Of course, you can ignore the NEC if your local code has loopholes that permit homeowners to use 15A outlets. But even if that was the case, the appliances that require a 20A circuit would overwhelm 15A outlets, causing the breaker to trip.

Don’t forget: the GFCI will not respond to overloading. It is designed to defend homeowners against electrocution in the event of a ground fault. It cannot stop fires caused by overloading.

You have to rely on the breaker to play that function. But if the breaker refuses to respond because of a defect or malfunction, an overloaded 15A circuit in a kitchen, bathroom, or garage could start a deadly electrical fire.

I replaced gfci and regular amp outlets with the same 20 amp outlets that are in a series. None of the outlets are working. Do the gfci outlets have to be pressed in order to open the system? Both the test and other button do not seem to click on and the light on the front does not light up. Can you give advice. Ready to call an electrician.

Check wiring connections and reset GFCI outlets by pressing the “Reset” button. Test outlets with a GFCI tester or plug in a device. Ensure circuit breakers are not tripped. If issues persist, consider contacting a licensed electrician for assistance.

Why a GFCI Keeps Tripping (Solved)

Hubert Miles | Licensed Home Inspector, CMI, CPI

Updated on February 17, 2024

There are several different reasons why a GFCI keeps tripping. The most common reason is water or moisture that has gotten into the receptacle box or outlet. However, a tripping GFCI device could also get caused by an overloaded circuit, a malfunctioning outlet, electrical issues, or improper installation. 

According to the National Electric Code (NEC), you must install Ground Fault Circuit Interrupter (GFCI) outlets and breakers in specific locations throughout your home. GFCI protection offers an extra layer of protection to your home’s electrical system. Still, they can be highly inconvenient if they’re constantly tripping and killing power to your outlets. 

When a GFCI keeps tripping, it’s inconvenient, but it often happens for a reason. You must get to the root of the cause behind your tripping outlet or breaker, especially if the electrical problems persist. It’s also essential to understand the purpose of GFCI devices and why electricians install them in the first place.

What is the Purpose of GFCI? 

Ground fault circuit interrupters protect you from a fatal electrical shock around your home. GFCI devices can detect small electrical leaks between hot wires and neutral wires.

A ground fault occurs when the incoming electrical current flow exits on the hot side of the outlet but doesn’t return the same electric current flow to the neutral side. If the current flows aren’t the same, the device will trip and terminate electricity like a breaker. 

An electrical leakage current is when the electric current deviates from its intended path. The electric leak will attempt to take the shortest unintended path to the ground, creating an electric shock that can be fatal.

While there’s usually a good reason for a GFCI outlet to trip, it can also happen accidentally. Accidental trips are highly inconvenient and are often the result of improper wiring or installation or a faulty outlet. However, whenever a GFCI outlet is not working , you must get to the bottom of the problem, or it will keep happening. 

What Causes GFCI to Trip? 

Troubleshooting your GFCI devices is often a process of elimination. There are five main reasons why these outlets and breakers trip, and it’s challenging to put your finger on the right one without an in-depth investigation. To help you get started, let’s go over the five main reasons why GFI outlets trip and what to do about it. 

There is Moisture Near the Outlet 

The most common reason GFCI outlets trip is because of moisture or water in the outlet or outlet box. Water is hazardous around electricity, so GFCI outlets often get installed in potentially moist areas. These include bathrooms, kitchens, laundry rooms, outdoor areas, and unfinished basements or attics. 

A physical splash of water is typically the cause of moisture in an outlet box and is easily detectable. However, in humid areas, such as Florida, it’s also possible for enough humidity to accumulate inside the outlet and cause it to trip.  

The best way to prevent this is to install a new GFCI outlet and box with extra protection. Modern GFCI outlet boxes are waterproof and can withstand rain, humidity, and flooding. You should replace your old GFCI outlet with one to prevent further tripping. 

Exterior outlets need GFCI protection and a bubble-type weatherproof cover to keep moisture at bay.

An Overloaded Circuit 

Another common reason your GFCI will trip is an overloaded electrical circuit. An overloaded circuit happens when you are trying to operate too many appliances or electrical devices on the same circuit. Depending on the size of your electrical wiring, your GFCI circuit can only handle so much power. 

An overloaded circuit can short circuit due to faulty or exposed electrical wiring. If two exposed wires are touching one another, it will cause the GFCI breaker or receptacle that’s powering them to trip. Unplug all the devices receiving power from the GFCI circuit breaker or outlet to determine if an overloaded circuit is a problem. 

Next, plug everything back in, one device at a time, and see if the problem reoccurs. If it does, an overloaded circuit is likely the cause of your tripping GFCI.

Plugging appliances in one at a time is also an excellent way to determine which appliance is causing the problem. It may be necessary to wire it into a separate circuit or run a new circuit entirely. 

A Ground-Fault Occurrence 

Ground faults are when the hot wire touches the ground wire or something grounded. Ground faults get caused by several different things, including: 

• Worn out insulation 

The older your electrical wiring is, the more likely it is to have worn-out wiring insulation. When the insulation wears down enough, the hot wire can contact the ground wire and cause a ground fault. 

• Corroded wires 

The same is true for corroded or pinched wires.  

• Dust or debris 

If enough conductive dust collects in the outlet box, it can become an electrical conductor and leak electricity from the hot wire to the ground. 

• Loose connections

When either a hot or neutral wire connections are loose, arcing (short circuit) occurs, which will trip the GFCI. The loose wire connection can be anywhere on the branch circuit between the circuit breaker and the GFCI receptacle outlet.

If you can’t visibly see the ground wire touching the hot wire, there’s still possibly enough electricity leakage to cause a tripped GFCI. You should contact a professional electrician or use an electricity leakage tester to see if this is the problem. If the insulation is worn enough, electricity can leak from the hot wire onto the ground. 

• Defective appliances

A defective appliance can cause GFCI tripping to occur. A hairdryer can be a defective appliance. Defective electric motors inside common household appliances can cause current leakage, tripping a GFCI.

Nuisance Trips from a Refrigerator or Freezer

When a refrigerator trips a GFCI outlet, this usually means that it is drawing too much power from the circuit, usually when the compressor turns on. To prevent further trips, check if too many appliances are plugged into the same circuit and unplug any unnecessary items.

In older homes, it’s common for the kitchen lights and outlets to share one circuit. Since the refrigerator shares the circuit, the excessive draw can cause the refrigerator trips the GFCI breaker or outlet.

Be sure the outlet your refrigerator is plugged into has a 20-amp rating. If not, consider installing a dedicated 20-amp circuit for the refrigerator.

Many people like to put a spare refrigerator or freezer in their garage . These can often trip GFCIs that the NEC requires inside garages. If your new refrigerator keeps causing GFCI outlet trips, consider plugging it into a different outlet or installing a dedicated circuit.

Your Outlet Has Gone Bad

Like all electrical devices and components, outlets tend to go bad. On average, GFCI outlets last 15 to 20 years, but they can last longer or shorter depending on how your licensed electrician installed them. However, a faulty GFCI outlet will trip for no reason other than that it can’t handle electricity. 

It’s good to test your electrical outlets once a month by pushing the TEST button on the outlet’s face. If it trips, the power outlet is working as it should. Press the RESET button once you have finished your test. 

Improper Installation 

Finally, it’s possible that you or an electrician didn’t install the GFCI outlet correctly. GFCI outlets have to get wired a certain way, and attaching the wrong wire to the wrong spot will cause your device to trip endlessly or not work. 

How to fix a GFCI that Keeps Tripping? 

When a GFCI outlet keeps tripping, it signals that a problem exists and needs your attention. The only way to permanently fix a GFCI that keeps tripping is to get to the root of the problem.

Nuisance tripping occurs when a GFCI trips for no apparent reason. Getting to the source of the problem of nuisance trips is the only way to ensure that tripping doesn’t reoccur, and you should take this seriously.

Your qualified electrician will likely need to replace the GFCI outlet or breaker and ensure no loose connections exist.

GFCI Keeps Tripping FAQs 

When a GFCI keeps tripping, you probably have questions about how to troubleshoot why nuisance GFCI tripping occurs frequently.

Can moisture cause a GFCI to trip? 

Moisture is one of the leading causes of a tripping GFCI outlet. Water can result from excess humidity, rain, or flooding. 

Will a GFCI trip if it’s overloaded? 

A circuit overload is when you try to power too many devices on the same circuit, and it will cause your GFCI to trip as a safety measure. 

What causes a GFCI to trip repeatedly?

A GFCI may repeatedly trip if there is an electrical fault, such as a short circuit, or a ground fault, meaning the electricity exits the outlet via an unnatural path. It can also be caused by moisture exposure, worn-out wiring, overloaded circuits, or a bad GFCI sensor.

Final Thoughts 

While tripping GFCI outlets is inconvenient, it’s a safety measure. In most cases, a tripping GFCI outlet is good and prevents you from getting electrocuted. These devices rarely trip for no reason, but they can happen. Whether you perform tests yourself or hire an electrician, you must get to why your GFCI is tripping in the first place.

When it comes to electricity, safety has always been a major concern, but thanks to the development of ground fault circuit interrupter outlets (GFCIs), the risk of being severely shocked or electrocuted is greatly reduced. According to the Electrical Safety Foundation International (ESFI), electrocutions are down 83 percent since the 1970s when GFCIs were introduced. These quick-to-react outlets are required by law in new home construction, and it’s a good idea to put them in older homes as well. Read on for must-know info on GFCIs—what they are, how they work, and where to install them.

RELATED:  These Electrical Safety Tips Could Save Your Life

What is a ground fault?

In your home, the flow of electricity is contained within wires covered with rubber- or plastic-based insulating material. When everything goes as planned, the electrical current runs safely through the insulated wires to switches and wall outlets and on to the many appliances and gadgets we take for granted today. But in its raw state, electricity has a “mind” of its own, and left to its own devices—as evidenced by most lightning strikes—it makes a beeline for the ground.

A ground fault is the occurrence of electricity taking an unintended path to the ground. It occurs when the electrical current escapes the insulated wires, as a result of a damaged cord or faulty wiring , and flows through a different conductor. If that different conductor is a human being, the result can be a serious electrical shock or electrocution. Because water is an excellent conductor of electricity, the risk of a ground fault occurring is greater in areas of your home where water is commonly used, such as near a kitchen sink.

How do GFCIs work?

The singular purpose of a GFCI outlet is to prevent electrical injury to humans, something regular outlets are not equipped to do. A standard household outlet features two, three-prong plug-in slots, while a GFCI outlet features the same plug-in configuration plus two buttons on its face: a “TEST” button and a “RESET” button. The rules requiring the installation of the GFCI outlets in new construction has expanded over the years to include more applicable locations:

1973 – exterior outlets 1975 – bathroom outlets 1978 – garage outlets 1987 – any outlet within six feet of a kitchen sink 1987 – at least one basement outlet 1990 – crawl spaces 1993 – wet bars 1996 – every kitchen outlet that serves a countertop 1999 – electrically heated floors

Normally, electrical current flows at a uniform rate through wiring, but when a ground fault occurs, the flow of electricity surges as it jumps to the unintended conductor. A GFCI outlet contains a sensor that monitors the flow of the electrical current through the wires, and when it senses a ground fault (in electrical terms, “fault” means any variation from the normal current), the GFCI, which also contains an internal switch, shuts off the flow of electricity in the outlet.

While you may still receive a painful shock, the GFCI will prevent a prolonged surge of electricity, the type that injures and kills. A standard outlet, like the type in your bedroom, doesn’t have a sensor.

Where should GFCIs be installed?

The National Electric Code (NEC) requires the installation of GFCI outlets in new construction in areas where electrical outlets are in close proximity to water. Older homes are not required to have GFCI outlets unless the wiring is being updated, but it’s a good idea to install them anyway.

The NEC requires GFCIs on all exterior and bathroom receptacles (another term for outlets). GFCIs are also required on all receptacles serving kitchen countertops. In laundry rooms and utility rooms, GFCIs should be installed on outlets within six feet of sinks, washing machines, and water heaters. They should also be installed within six feet of a wet bar and in garages and unfinished basements.

In bedrooms, living rooms, and other areas where water fixtures are not found, regular outlets are fine—and they are still installed in today’s new homes. The ESFI estimates that approximately 43 million homes in the U.S. still do not have GFCIs installed in “wet” rooms, and notes that as many as 47 percent of today’s electrocutions could be prevented in older homes if GFCIs were installed.

Can I install GFCIs myself?

A DIYer with basic knowledge of electrical wiring may be able to replace an existing outlet with a GFCI outlet (instructions below), but only when swapping out a three-prong outlet—two plugin slots and a hole. Outlets with only two slots and no third hole indicate the presence of older wiring that should only be replaced by a licensed electrician.

The other caveat is that only outlets connected to three wires are suitable for DIY replacement. Outlets with three attached wires (remove the outlet plate to determine the number of attached wires) indicate that the outlet is located at the end of an electrical circuit (a wiring loop that starts and finishes at the breaker panel). An outlet with five attached wires is located in the middle of an electric circuit, and the wiring process is more complicated—only a licensed electrician should replace those outlets.

A GFCI outlet runs about $15, such as this Levitron GFCI Outlet (available from Home Depot ). An electrician will charge an additional $50 to $100 dollars per hour to replace outlets.

Replacing a GFCI Outlet Yourself

Replacing an existing outlet at the end of a circuit (as explained above) is not particularly difficult, but the task requires some experience. You should understand how outlets are wired and how electrical current travels from the breaker panel through each electrical circuit (wiring loop) in your home. Some communities prohibit homeowners from doing their own wiring, so check with your local building authority before you start.

MATERIALS AND TOOLS – Flat screwdriver – Phillips screwdriver – Flashlight – GFCI outlet – GFCI outlet cover

Shut off the power to the outlet by turning off the circuit breaker (at the breaker panel) that provides electricity to the outlet. A good way to ensure that the power is off is to plug a nightlight into the outlet and turn it on, then shut off the breaker. If the nightlight does not go off, you’ve got the wrong breaker—try again.

Remove the outlet cover with a flat screwdriver. You’ll probably need a helper to hold a flashlight for you now, since the overhead light might also be off.

Remove the old outlet from the outlet box using a Phillips screwdriver. The outlet is typically held in place by two screws at the top and two at the bottom. When the screws are removed, the outlet will hang freely—the only things holding it are the attached wires.

Remove the three attached wires, which are held in place with Phillips screws. Note the color of the screws and the color of the wires .

• Black (hot) wire connects to a brass or gold screw on one side.
• White (neutral) wire connects to a silver screw on the opposite side.
• Green or copper (ground) wire connects at the bottom of the outlet to a green screw.

Attach the new GFCI outlet in the same way you disconnected the old outlet, making sure the wires attach to the screws using the above color-coded method. The GFCI outlet will also have two additional screws on the bottom sides, and these screws will be covered by a piece of tape. Leave the tape in place—these screws are for use by an electrician who is replacing an outlet in an advanced wiring situation.

Fasten the new GFCI outlet to the outlet box with Phillips screws (use the same holes).

Position the new GFCI outlet cover over the outlet and attach it with flat screws. A new outlet cover is necessary because the cover of a standard outlet will not fit a GFCI outlet.

Turn the circuit breaker back on.

Press the “Reset” button on the front of the GFCI outlet to turn it on and plug the nightlight in to test it.

Leave the nightlight in and then press the “Test” button. The nightlight should go off, which tells you that the GFCI outlet is working as intended. If it’s not working, it’s time to call the electrician.

How should I care for GFCI outlets?

Once installed, a GFCI outlet needs virtually no additional care, although you might want to press the Test button once a month or so to make sure it’s still functioning properly. Occasionally, a GFCI will shut itself off for no apparent reason—known as “nuisance trips” or “ghost trips.” This can be caused by something as simple as static electricity or nearby lightning. When this happens, just press the Reset button to restore electricity.

If a GFCI trips frequently when not in use (daily or weekly), the outlet itself could be worn out or faulty and should be replaced.

Since the expansion of the 2017 National Electrical Code (NEC) ground fault circuit interrupter (GFCI) requirements to include single-phase receptacles up to 50A and three-phase receptacles up to 100A, we’ve seen a trend of increased GFCI nuisance tripping. While these trips can be frustrating, it’s important to not create a code violation or put personnel at risk by removing GFCI protection. Often, a tripping GFCI device may be operating properly; it’s possible there is an equipment or wiring issue that needs to be addressed.

At Henderson Engineers, we’ve compiled the following information to help our clients understand why they may be experiencing an issue and suggestions on how to address it.

What is GFCI protection?

GFCI devices have been credited with saving numerous lives since their introduction to the NEC in 1971. This protection can be achieved via a GFCI circuit breaker or a GFCI receptacle. These devices reduce electrocution risks by measuring the electrical current between the phase conductor and the neutral return. If the return current differs by more than 4 to 6 mA, a dangerous amount of current is flowing somewhere it shouldn’t be – so the device shuts off. Per the 2017 NEC, GFCI protection is required in bathrooms, kitchens, rooftops, outdoors, within 6’ of a sink, and select other areas.

The NEC commentary explains that they expanded GFCI requirements to include higher voltages and current ratings because equipment connected to those receptacles present the same shock hazards as those of lower voltages and current ratings. Unfortunately, this expansion of the GFCI requirements has led to more nuisance tripping and owner’s asking, “Why is my GFCI not working?”

Common Causes of GFCI Trips

1. There are too many appliances being protected by the GFCI.

Sometimes tripping occurs when a GFCI circuit breaker is protecting multiple downstream receptacles. If several appliances are connected to the GFCI device, the cumulative effect of the appliance leakage currents may trip the GFCI. To ensure proper operation, minimize the number of appliances protected by the GFCI. Depending on the circuit length from the GFCI sensing device, it may be necessary to limit the number of appliances being protected to one or two.

2. The circuit is too long for the equipment being protected by the GFCI. 

This is common in GFCI circuit breakers with circuit lengths over 150’. Capacitive leakages due to the wire length of the circuitry may exceed the threshold of the GFCI. (The actual length limitations vary depending on wire type and size.) To prevent this issue, place the GFCI device close to the equipment it will be protecting – this may mean using a GFCI receptacle or blank face GFCI device near a normal receptacle.

3. The GFCI was improperly wired by an electrician.

Have the installation checked to see if the GFCI receptacle and related circuitry are installed correctly. Verify the neutral is dedicated and connected to the correct circuit, etc. While testing of GFCI devices is not generally included in the basic scope of commissioning services, having a trusted third-party electrician or commissioning agent provide independent verification of proper installation may be necessary.

4. The area is too wet. 

If nuisance tripping is occurring in areas near dishwashing, mop sink, janitorial, ice machines, showers, walk-in coolers, exterior locations, roofs, and other areas with a lot of condensation, then too much moisture may be the cause. Check to see if there are any environmental or operational changes that can be made to reduce moisture near the appliance and receptacle. Installing a weatherproof cover plate at the receptacle may be helpful.

5. An appliance may have manufacturing defects. 

It’s possible an appliance may be leaking too much current to ground. Appliances are allowed a certain amount of leakage current per their UL listings; acceptable maximums may be as high as .75mA per appliance. Unfortunately, some equipment may not be built to the same standards as the prototype that passed testing. Now that more receptacles are required to have GFCI protection, equipment issues may be coming to light. If you have faulty equipment, contact the equipment supplier/manufacturer for repair or replacement.

6. The GFCI device may be defective. 

These devices don’t last forever, and some are defective even when new. UL 943 covers Class A GFCI devices. GFCI breakers and receptacles should be replaced in accordance with manufacturer’s recommendations. Best practice is to test GFCIs monthly and replace them every 5 years.

Best Practices

GFCI devices trip for several reasons. The following best practices can help confirm proper operation and reduce nuisance tripping.

• Minimize the number of appliances protected by each GFCI.
• Minimize the circuit length from the GFCI circuit breaker to the receptacle – a maximum conductor length of 150’ is good rule of thumb.
• Verify GFCIs are installed per manufacturer’s recommendations and as required per code.
• Avoid excessive moisture around appliances and receptacle.
• Replace defective appliances.
• Replace defective or GFCI devices that are more than 5 years old.
• Maintain easy access to GFCI devices in case they need to be reset. (The 2017 NEC requires GFCI receptacles to be “Readily Accessible.” That means one must be able to reach the device quickly, without having to use ladders or climbing over obstacles, like large stationary kitchen equipment. GFCI breakers or blank face GFCI devices are sometimes needed to meet this requirement.)

Although they can be frustrating, it’s important to remember, GFCI devices have been proven to save lives and are required by code. Proper application and maintenance of these devices is essential for personnel safety and smooth business operations.

Understanding Ground Fault and Leakage Current Protection

July 23, 2019 by

Ground-fault circuit interrupters (GFCIs) have been in use for over 40 years, and have proven themselves to be invaluable in the protection of personnel from the hazard of electric shock. Other types of leakage current and ground fault protective devices have been introduced for various applications since the introduction of GFCIs. The use of some protective devices is specifically required in the National Electrical Code® (NEC)®. Others are a component of an appliance, as required by the UL standard covering that appliance. This article will help to differentiate the various types of protective devices used today and clarify their intended uses.

GFCI’s

Following this definition, an Informational Note provides additional information on what constitutes a Class A GFCI device. It states that a Class A GFCI trips when the current to ground has a value in the range of 4 milliamps to 6 milliamps, and references UL 943, the Standard for Safety for Ground- Fault Circuit-Interrupters.

Section 210.8 of the NEC covers specific applications, both residential and commercial, where GFCI protection for personnel is required. In dwelling units, GFCIs are required in all 125-volt, single phase, 15- and 20-ampere receptacles installed in locations such as bathrooms, garages, outdoors, unfinished basements, and kitchens. Article 680 of the NEC covering swimming pools has additional GFCI requirements.

In almost every new edition of the NEC since 1968, new GFCI requirements were added. See the table below for examples of when the NEC first required GFCIs for various applications. Please note that this list does not include all locations where GFCI protection is required.

UL Guide Information for Ground-Fault Circuit Interrupters ( KCXS ) can be found in UL Product iQ TM .

Other Types of Leakage Current and Ground Fault Protective Devices:

LCDI (Leakage Current Detector Interrupter) LCDI’s are permitted for single-phase cord- and plug-connected room air conditioners in accordance with Section 440.65 of the NEC. LCDI power supply cord assemblies use a special cord employing a shield around the individual conductors, and are designed to interrupt the circuit when leakage current occurs between a conductor and the shield. UL guide information for Leakage-Current Detection and Interruption can be found under the UL Product Category ELGN .

EGFPD (Equipment Ground-Fault Protective Device) — Intended for applications such as fixed electric deicing and snow melting equipment, as well as fixed electric heating equipment for pipelines and vessels, in accordance with Articles 426 and 427 in the NEC. This device operates to disconnect the electric circuit from the source of supply when the ground-fault current exceeds the ground- fault pick-up level marked on the device, typically 6 mA to 50 mA. UL guide information for Ground-Fault Protective Devices can be found under the UL Product Category FTTE .

ALCIs and IDCIs

These devices are UL Component Recognized, and not intended for general sale or use. They are intended for use as factory-assembled components of specific appliances where the suitability of the installation is determined by UL. They have not been investigated for installation in the field, and may or may not satisfy requirements in the NEC.

ALCI (Appliance Leakage Current Interrupter) — A component device on electrical appliances, ALCIs are similar to GFCIs, as they are designed to interrupt the circuit when a ground fault current exceeds 6 mA. An ALCI is not intended to replace the use of a GFCI device, where GFCI protection is required in accordance with the NEC.

IDCI (Immersion Detection Circuit Interrupter) — A component device that interrupts the supply circuit to an immersed appliance. When a conductive liquid enters the appliance and contacts both a live part and an internal sensor, the device trips when current flow between the live part and the sensor exceeds the trip current value. The trip current may be any value below 6 mA sufficient to detect immersion of the connected appliance. The function of an IDCI is not dependent on the presence of a grounded object.

Proven Benefit of Leakage Current and Ground Fault Protection

To help mitigate electrical shock hazards, UL has been at the forefront of detector research, technology and standards development. Statistics have shown that devices described in this article have proven to be an effective means to improve safety in residential occupancies and other electrical installations. Proper application and use of these protective devices is critical to coordinating required protection for safe installations.

Common Causes of GFCI Outlets Keeps Tripping and How to Troubleshoot Them

Why Do My GFCI Outlets Keep Tripping?

Common causes of gfci outlets tripping, outlet keeps tripping after reset, outlet keeps tripping with nothing plugged in, outlet keeps tripping when i plug something in, outlet keeps tripping without load, how to troubleshoot gfci outlet tripping.

• Check for Ground Faults: Inspect the vicinity of the outlet for indications of moisture, like water leaks or dampness. Ground faults, which can cause GFCI tripping, can occur due to moisture. It's crucial to promptly address any water-related problems to prevent potential ground faults and ensure the safety of the electrical system.
• Inspect Wiring Connections: To prevent GFCI tripping, it is important to inspect the wiring connections within the outlet box. Check for any loose or damaged wires, as they can cause a GFCI to trip. Safely turn off the power to the outlet and carefully examine the connections, tightening any loose screws or terminals for proper installation and secure connections.
• Test GFCI Outlet Functionality: To ensure the functionality of a GFCI outlet, press the "Test" button to simulate a ground fault and check if it trips correctly. Afterward, press the "Reset" button to restore power. If the GFCI fails to trip during testing or doesn't reset properly, it indicates a potential fault, and the outlet should be replaced to maintain electrical safety.
• Identify Overloading Issues: It's important to be mindful of the current rating of GFCI outlets, usually 15 or 20 amps. If multiple appliances or devices connected to the outlet exceed this rating, it can cause tripping. Evaluate the number of devices connected simultaneously and redistribute the load accordingly to prevent overloading and subsequent GFCI trips.
• Examine Water Exposure: In areas prone to moisture, such as kitchens or bathrooms, it is crucial to protect GFCI outlets with waterproof covers. Water exposure from splashes or high humidity can lead to GFCI tripping. By installing appropriate waterproof covers, you can safeguard the outlet from moisture-related issues and ensure its proper functionality.
• Consult a Professional Electrician: If the above steps do not resolve the problem or if you are uncertain about handling electrical troubleshooting, it is wise to consult a professional electrician.

No More Tripping: Tips for Troubleshooting GFCI Outlets

Ground Fault Circuit Interrupter (GFCI) outlets are a crucial safety feature in modern homes, protecting people from electrical shocks and electrocution.

However, you may encounter a situation where a GFCI trips for no apparent reason. It can be frustrating, especially if it occurs frequently.

In this article, we’ll explore why a GFCI may trip for no apparent reason and provide tips on how to troubleshoot and resolve the issue.

Table of Contents

What is a GFCI and How Does it Work?

Before we dive into why a GFCI may trip, it’s essential to understand what it is and how it works. A GFCI is an electrical safety device that monitors the flow of electricity in a circuit.

It protects people from electrical shock by immediately cutting off power to the circuit when it detects an imbalance in the electrical current, also known as a ground fault.

The GFCI measures the amount of current flowing out of the hot wire and compares it to the amount flowing back on the neutral wire.

If there is an imbalance of more than 5 milliamps, it trips and shuts off power to the circuit.

For more information about the difference between GFCI and CB read my article here.

Why Does a GFCI Trip for No Apparent Reason?

There are several reasons why a GFCI may trip for no apparent reason, including:

• Overloading : GFCI outlets are designed to handle a certain amount of current. If you plug in too many devices or appliances, it can overload the circuit and cause the GFCI to trip.
• Moisture : GFCI outlets are commonly found in areas of the home that are prone to moisture, such as bathrooms, kitchens, and outdoor areas. If water or moisture gets into the outlet, it can cause the GFCI to trip.
• Faulty Wiring: Faulty wiring can cause a GFCI to trip. Wiring issues can include loose connections, damaged wires, or faulty installation.
• Ground Faults: A ground fault is when the electrical current flows through an unintended path, such as through a person’s body. This can happen if a person touches a live wire or a faulty appliance. The GFCI will trip to prevent electrocution.
• Aging: Like any electrical component, GFCI outlets can wear out over time. If your GFCI outlet is old, it may be more likely to trip for no apparent reason.

How to Troubleshoot a GFCI That Keeps Tripping

If your GFCI outlet keeps tripping for no apparent reason, here are some steps you can take to troubleshoot the problem:

• Unplug all devices from the GFCI outlet: If the GFCI outlet stops tripping when you unplug everything from it, the problem may be an overload of the circuit.
• Dry out the outlet: If the GFCI outlet is located in a moist area, such as a bathroom or kitchen, make sure it is dry. You can use a hairdryer or fan to dry out the outlet.
• Check for loose connections: Make sure all wires are properly connected to the GFCI outlet. Loose connections can cause the outlet to trip.
• Test the GFCI outlet: You can test the GFCI outlet by pressing the “test” button. If the outlet does not trip when you press the test button, it may be working correctly. However, it’s still a good idea to replace it if it’s old or has been tripping frequently.
• Call an Electrician: If you’ve tried all the above steps and the GFCI outlet keeps tripping , it’s time to call an electrician. A professional can help you diagnose and repair any wiring or installation issues that may be causing the GFCI to trip.

Preventing GFCI Trips

While there are various reasons why a GFCI may trip for no apparent reason, there are some preventative measures you can take to reduce the chances of it happening:

• Do not overload the circuit : Avoid plugging too many devices into a single outlet or circuit. Spread out the load to other outlets in the room.
• Keep GFCI outlets dry: Moisture is a common cause of GFCI trips. Keep GFCI outlets dry, especially in areas such as bathrooms, kitchens, and outdoor areas.
• Regularly check wiring connections: Check for loose or damaged wiring and repair them promptly.
• Test GFCI outlets regularly: Test GFCI outlets regularly using the “test” button to ensure they are working correctly.

Here’s a table summarizing the reasons why a GFCI outlet might trip and some preventative measures you can take to avoid those issues:

By following these preventative measures, you can reduce the chances of your GFCI outlet tripping and keep your home safe.

• GFCI outlets are an essential safety feature in modern homes, but they can trip for no apparent reason.
• Overloading, moisture, faulty wiring, ground faults, and aging can cause a GFCI to trip. If your GFCI outlet keeps tripping, there are several troubleshooting steps you can take, including unplugging devices, drying the outlet, checking for loose connections, and testing the GFCI outlet.
• If the problem persists, it’s time to call an electrician. By taking preventative measures such as avoiding overloading circuits, keeping GFCI outlets dry, regularly checking wiring connections, and testing GFCI outlets, you can reduce the chances of GFCI trips and ensure the safety of your home and loved ones.

5 Reasons Your Ground-Fault Circuit Interrupter Outlets Keeps Tripping

Ground-fault circuit interrupters are designed for your safety. Circuit interrupters, or "trips" as they are commonly referred to, are intended to reduce the risk of fire or electrocution. If they trip, it's an indication there is a problem and you'll need an electrician you can trust.

What Causes Ground-Fault Circuit Interrupter To Trip?

The top five reasons your GFCI outlet keeps tripping are ground-fault occurrences, moisture in the receptacle box, an overloaded circuit, an electrical fault, and a faulty GFCI outlet. We'll cover each of these issues, including causes and solutions.

1. Ground-Fault Occurrence

Ground faults occur when the hot wire or live wire comes into contact with the ground wire or the grounded area of an appliance. Usually, GFCIs function by detecting when the current is flowing along an unintended path (e.g., through water or a person).

The instant the GFCI detects there is even the slightest of current leakage as low as 0.005 amps, it trips right away.

How do you determine if the current is leaking? Unplug everything on that circuit and make sure all the switches are off. Check for any wear that may have occurred to the equipment. Any slight damage means the electrical part is no longer protected from contact.

2. Moisture in the Receptacle Box

The accumulation of moisture is another major cause of GFCI tripping. Outdoor GFCI outlets are the most vulnerable, and rain is the most common culprit. However, due to the tropical climate of Florida, high humidity can also cause moisture buildup and make it harder for any water trapped in a receptacle box to evaporate.

Start your search by inspecting the receptacle box. Be sure to turn off the breaker before opening the box containing the receptacle. The box must be dry before you attempt to reset the GFCI. It is possible to speed up this drying process using a simple tool such as a blow dryer, but that part is best left to a professional.

If the installation is outdoors or located in high humidity areas, such as the bathroom or kitchen, make sure the box is weatherproof and locked even when the receptor is in use. The presence of moisture can expose you to the risk of accidental electric shock.

3. Overloaded Circuit

Circuit overload occurs when more amperage flows through an electric wire or circuit than it can handle. This may happen if you connect malfunctioning or defective appliances. Loose, corroded wires or connections may also be to blame. Once the GFCI outlet senses an overload, it trips or "breaks" the circuit.

If you want to determine if overloading is really the problem, follow these steps in order.

• Unplug all the appliances connected to the circuit in question
• Reset the circuit on your fuse box
• Wait several minutes
• Plug an appliance back in and turn it on
• Check to see that your circuit has not tripped
• Plug in the next appliance, turn it on, check the breaker, and so on

You may find you'll need to replace the items causing the problem.

If the problem keeps reoccurring, you may need a new dedicated circuit and outlet that can handle the amperage required by the appliances.

4. Electrical Fault

If your GFCI outlet trips consistently, it could be an electric fault resulting from faulty structural wiring. An electrical outlet connected to the same circuit could also be the source of the problem, especially if it was not part of the original wiring of your home. In the case of an electrical fault, you will need a professional electrician to fix the problem.

5. Faulty GFCI Outlet

If you've tried all else and the GFCI outlet reset doesn't solve the problem, that means the outlet itself is defective. GFCI outlets have highly responsive internal circuitry to detect whenever there's a flaw in the electric system. With time, the sensitive circuitry wears out, rendering the outlet dysfunctional. In this case, the outlet will need repairing or even replacing and should be done by a qualified electrician.

Update: Resolving the GFCI Nuisance Trip Issue for HVACR  

Posted on: January 19, 2023

Recently ACCA and an industry coalition successfully convinced the National Fire Protection Association Standards Council to approve an exception to the National Electrical Code (NEC) regarding the requirement for a ground-fault circuit interrupter (GFCI) device for outdoor equipment. The new exception to 210.8(F) exempts listed outdoor HVACR equipment from having to comply until September 1, 2026. This change was approved for the existing 2020 NEC and also appears in the newly published 2023 edition. However, when the above date expires, what then? There’s a lot going on in the new year to prepare for the expiration date, so read on.  

How We Got Here  

Over the past few code change cycles (they occur every three years), the NEC was revised to expand the applications requiring GFCIs for personnel protection to mitigate the risk of electric shock. The application of GFCI devices in the 2020 NEC was expanded to include outdoor heat pumps and air conditioners. However, when GFCIs were installed on such equipment in the field to comply with the new code, it created numerous nuisance trips, rendering the equipment inoperable. This occurred primarily in early adopting states like Minnesota and Texas. The prevailing theory is that the tripping may be caused by high-frequency harmonic signals emitted by nonlinear electrical loads, such as variable speed drives or frequency inverters. This technology is becoming more prevalent for heat pumps and air conditioners complying with the new Department of Energy (DOE) efficiency standards, which took effect on January 1 of this year.  

Fixing the Code: NEC 2026  

The ink is barely dry on the 2023 edition and now a new NEC code change cycle has begun. We must work fast not only to find and verify the cause of the nuisance trip problems in the field but also to propose solutions for the relevant safety standards and potentially for the NEC itself. In order to provide our industry’s input to the upcoming NEC code cycle, ACCA and other industry allies applied for voting membership on the NEC Code-Making Panel 2, which is responsible for the GFCI coverage in the NEC.   

Standards Activities Related to GFCI Issues  

Several UL standards address the electrical incompatibility issues between HVACR equipment and Class A GFCI devices. On the equipment side, there is UL 60335-2-40, which is the safety standard for electric heat pumps and air conditioners. Current proposals seek to distinguish between the terms “leakage current” and “touch current,” which is defined as the electric current through a human body when it touches one or more accessible parts of an installation or equipment. Another proposed option provides a dual “protective earthing conductor” system with a monitoring device that interrupts all supply conductors when it detects an open circuit on the protective earthing conductors. It is believed that this latter feature is intended to be utilized in lieu of a GFCI device. In addition, the UL 101 Standard for Leakage Current for Utilization Equipment has recently proposed a “GFCI Interoperability Test.” This test is intended to evaluate the appliance’s ability to operate as intended on a circuit that is protected by a Class A GFCI. Currently, this investigation has been focused only on household appliances, and other types of permanently connected products, such as 240 V HVAC equipment, have not yet been studied. It is expected that the UL 101 proposals will ultimately be coordinated with the other UL standards, such as UL 60335-2-40 and the UL 943 standard for GFCI devices.   

GFCI Research Project  

In response to the nuisance tripping issues, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) began a research project last year to find and document the causes of the problem. The research is being conducted by the Electric Power Research Institute (EPRI). Phase 1 of the project has been completed, and a report is expected sometime this spring. Once the problems have been identified and verified in the laboratory, the research is expected to determine proposed technical solutions, coordinate those solutions with the above-mentioned UL standards groups, and potentially support additional proposed changes to the NEC.  

Other Nuisance Tripping Problems   

ACCA is investigating other nuisance tripping issues created by Class A GFCI devices, which are required on basement receptacles per the NEC. One example is condensing furnace condensate pumps located in basements, which according to contractor reports, has resulted in flooding damage. Another potential tripping issue includes condensate pumps used for air-handling equipment in basements or the furnace itself if it has a variable speed ECM blower motor. The issue has been raised that all electronically commutated motors (ECMs) can be impacted by Class A GFCI devices in the same way as variable speed compressors. At this time, it is not determined if this is an installation practice issue or an issue that must be resolved in the codes and standards arena.  

ACCA is Involved  

ACCA continues to lead the way in working with allied associations to resolve the GFCI nuisance issues in codes and standards. We are coordinating with groups such as the National Association of Home Builders (NAHB), the Leading Builders of America (LBA), the AHRI, and others to achieve this goal. ACCA’s Codes Subcommittee also provides guidance in this effort. Our contractor members are in a precarious position in that any potential nuisance tripping issues in the field can adversely affect their reputation and business as well as create customer doubts about the equipment they are installing. We will continue to keep our members informed as developments dictate throughout the year.

It can be frustrating when one of your home’s electrical outlets stops working. Luckily, you can take steps to diagnose the issue yourself before calling an experienced electrician . Read our guide to learn more about how electrical outlets work, how to fix them, and when to contact a professional.

How Do Electrical Outlets Work?

Electricity travels from the power plant through power lines and connects with your breaker box to power your home. The breaker box distributes electricity to various circuits, each powering a different area of your home. A breaker controls each circuit and turns off if the system has an electrical overload.

Electrical outlets allow your appliances and other devices to access the electricity in the circuit. Your outlet has three main parts:

• The ground hole: Most electrical outlets have a grounding hole, which is the semicircular hole at the bottom of the outlet. The ground hole provides a safe path for electrical currents to flow before they reach the appliance, which prevents shocks and protects your electronics.
• The hot slot: This is the smaller slot on the face of the outlet. In North America, it delivers 120V worth of electricity.
• The neutral slot: This is the larger slot on the face of the outlet that completes the circuit, allowing electricity to flow back to the circuit breaker. It has a neutral voltage.

When you plug a device into an outlet, its metal prongs fit into the hot and neutral slots, completing the electrical circuit that powers it.

Here are the most common types of outlets you’ll find in North American homes:

• Ground fault circuit interrupter (GFCI): This type of outlet is typically located in your bathroom or kitchen and is identified by its test and reset buttons. GFCIs automatically shut off power if they detect an interruption in the electrical flow to prevent serious electrical shock.
• Grounding 3-prong outlets: Most residential structures have building codes that require these standard outlets. They have two slots for standard plugs and a grounding hole for safety.
• Standard 2-prong outlets: You’ll find these outlets in many older homes. If you have standard 2-prong outlets, consider replacing them since they’re less safe than newer ones.

Common Problems With Electrical Outlets

Even new electrical systems can experience problems that disrupt your electrical circuit and make your outlet useless. Some issues are easy to tackle yourself, while others might require the help of a licensed electrician .

Check that the problem isn’t with the plug on your device before you try to fix your electrical outlet. Plugs on appliance cords can wear out, and bent prongs or frayed wires may prevent the plug from connecting to the outlet.

GFCI outlets are great for areas of your home that experience a lot of moisture, such as your bathrooms and kitchen. These outlets monitor the flow of electricity and turn off if they detect an imbalance that could lead to an electrical shock. A tripped GFCI prevents appliances plugged into the outlet from working.

Wires connect the outlet to the circuit. These wires can loosen over time due to an incorrect installation or vibrations in the walls. Loose connections can disrupt the flow of electricity, causing flickering lights or a complete loss of power to the outlet, depending on how loose the connection becomes.

A tripped circuit breaker is the most common reason for a dead outlet, but it’s also the easiest to fix. If there’s too much demand on the circuit, the fuse box will turn that circuit off to prevent overheating and becoming a fire hazard. If all the electrical outlets and electronics in that area of your home have stopped working, your dead outlet is probably due to a tripped circuit.

Outlets can deteriorate over time, especially if they get a lot of use. Faulty outlets might develop loose wires, worn-out connections, or physical damage to the outlet itself. A worn outlet won’t be able to deliver consistent power, so you might notice flickering lights or sparks when you plug something in. Since old, damaged outlets can be a fire hazard, you should replace them immediately.

You may be able to fix a dead outlet yourself. Before diagnosing the issue, turn off the power to the outlet at the breaker box. The electrical box is typically found in a basement, garage, or utility closet. Identify the breaker controlling the circuit on the electrical panel and flip it to the off position.

Here’s how to troubleshoot an outlet that isn’t working:

Check the fuse box

Test another electronic device, reset the outlet, inspect the outlet plate, check the wires.

Tripped breakers are the most common cause of broken outlets. If the breaker controlling the outlet is in the off position, flip it back on. Then, go back to the outlet and see if it has power.

Sometimes, the issue is with the object that needs power, not the outlet itself. Plug a device, such as a lamp or phone charger, into the outlet. If the item works, the outlet is fine and the issue is with the plug on your electronics.

If the power outlet has a test and reset button, it’s a GFCI outlet. This type of outlet provides extra protection against electrical shocks in areas with high moisture. Press the test button, which should pop out the reset button. Press the reset button and then see if the outlet works.

Remove the outlet faceplate by unscrewing it with a screwdriver. Most faceplates have one or two screws and are easy to remove. Look for signs of damage to the outlet, including cracks, bent hardware, or burn marks. If the outlet is damaged, you may need to replace it with a new outlet cover .

Visually inspect the wires connected to the outlet faceplate, being careful not to touch them. They should be secure and not show any signs of fraying or loosening. If they look loose or damaged, contact an electrician about fixing them.

When To Contact a Professional Electrician

There are some simple do-it-yourself (DIY) ways to fix a broken outlet, but some situations require a licensed electrician. The sections below detail when it’s time to call a pro.

If you’re experiencing electrical system issues in other parts of your home, it’s best to talk to an electrician. Flickering lights, dimming lights, or buzzing sounds from light switches are all signs of potential issues. These signs are especially common in older houses with aging electrical systems. A licensed electrician can assess your electrical system and work with you on a plan to update and improve its safety and function.

If you find yourself resetting the same breaker frequently, it could be a sign of a bigger electrical issue. A breaker that trips often or doesn’t work after you’ve reset could be overloaded, or there may be a wiring issue. Resist the urge to keep resetting a blown fuse and instead call a licensed electrician.

If you smell burning plastic or rubber near the electrical outlet, the wiring may be overheating and could become a fire hazard. Other signs of electrical fires include sparks, smoke, crackling sounds, or an outlet that feels warm to the touch. If you observe any of these signs, turn off the power at the breaker immediately and contact an electrician. These are all signs of serious electrical problems—don’t attempt to fix them yourself.

• Ask about their experience, particularly about working on issues like yours.
• Check their online reviews to see what previous customers say about their services.
• Choose an electrician who communicates well, answers your questions, and gets back to you promptly.
• Ensure that the electrician you choose is licensed in your state and carries liability and workers’ compensation insurance.
• Get estimates from multiple electricians before committing to one (the cheapest isn’t always the best).

A malfunctioning outlet can be a major inconvenience, but you can often fix the issue yourself. Turn the circuit off at the fuse box and start with straightforward solutions such as resetting the breaker or pressing the reset button on your GFCI outlet. Next, you can look for signs of loose or faulty wiring.

If these solutions don’t restore electrical service to your outlet, contact a licensed electrician to diagnose and fix your dead outlet. If you see any signs of electrical fires, turn the electricity off at the breaker box and contact an electrician immediately.

Why would an outlet suddenly stop working?

An outlet may suddenly stop working because of a tripped breaker, a faulty GFCI outlet, or wear and tear on the outlet itself. An outlet may also stop working due to damaged wiring or power surges.

How do you fix a dead outlet?

You can attempt to fix a dead outlet by checking the breaker box, as tripped breakers are the most common cause of malfunctioning outlets. If that’s not the problem, consult a qualified electrician.

Can a bad outlet cause others not to work?

In most cases, a bad outlet won’t cause other outlets to stop working. However, if several outlets in the same area of your home stop working, it’s probably due to a tripped breaker.

Buying Guide

This buying guide is for your assistance to buy the best GFCI outlet for your home. It also contains the questions that you might appear in your mind when you think about purchasing a receptacle. This buying guide will assist you regarding different aspects that you should consider when buying the best GFCI outlet.

Despite the fact that most of the residential GFCI outlets have pretty much similar features to offer but some of the aspects make a specific outlet outperform other options available on the market.

What is a GFCI Outlet?

We all have GFCI outlets in our homes yet, many of us are not aware of their purpose. GFCI receptacles are the power outlets that are mostly found in the washrooms of our homes (or near the refridgerator).

You can quickly identify these GFCI outlets with the couple of buttons found on their face: one of them is for test and the other one for reset. When electric current flows through the devices, it begins from the hot terminal and returns to the ground.

It is where the GFCI plugs come in to play its part. It compares the current leaving the hot terminal and the current that returns to neutral.

If there is a sizeable difference between the two, then the receptacle knows that there is a leakage somewhere. If there is a danger due to water damage or electrocuting, then the outlet will shut off the electricity to prevent any harm to you.

These GFCI outlets are very good at keeping you safe from electric shocks, and you need to have one in your home. Although they have a similar name to a USB wall outlet – their function is completely different. One is for protection (GFCI outlet), the other is for convenience (USB wall outlet).

GFCI outlets protect you from faults that occur inside your home. Other protection devices include surge protection devices. A good whole home surge protector acts as the first line of defense when lightning or utility-related surge events occur outside of your home. The next line of defense is surge protectors that exist at the power points within your home, such as a surge protector for washing machines and refrigerators . Combined, these protection devices protect you and your electronic devices from both internal and external fault events or electrical irregularities.

What is a ground fault circuit interpreter for when I have circuit breakers?

If you are looking for complete protection, then you should have both of these devices. Circuit breakers keep you safe from any electric shocks or even fire that may result from current overloads.

On the other hand, GFCIs are far more sensitive because they can respond to any lower levels of fluctuations that cannot trip a breaker. If you’re unsure if you have a circuit breaker in your home, you can use a good circuit breaker finder to identify where these circuit breakers might be.

Should I buy a 15-Amp outlet or a 20-Amp outlet?

Most of the products have same features with a few additions. You can also use 20-Amp GFCI outlets for larger setups. However, most of the residential users can opt for a 15-Amp outlet, and it will serve well.

There is not much difference between the two except that 20-Amp GFCIs are used bigger circuits. 20-Amp outlet is more potent than 15-Amp, and it can detect slightest of fluctuations too which are not very common in commercial use.

Why should I consider the dimensions of a GFCI outlet?

Slimmer GFCI outlets can only take about 25% lesser space in the wall box or even on the wall. Traditional GFCIs that thicker than the slim ones. In addition to the size; installation of the thinner devices is far more comfortable than, the larger, bulkier outlets.

Why must the lockout feature be patented?

The patented lockout feature is a standout, preventing the device from resetting if it’s incapable of responding to a fault or if there’s incorrect wiring, enhancing its reliability and your safety. Some traditional receptacles can reset even if it is not providing any protection.

Is there any Code requirement for the installation of the GFCI outlets?

As per National Electric Code, GFCIs are required to be installed in damp areas including washrooms, kitchens, laundry rooms, basements, porches, garages or any other area where there is a water source present.

Do I need to test a GFCI before buying?

It is recommended that the GFCI outlets that are not UL listed should be tested before buying. The GFCIs outlets should be checked on a monthly basis to make sure that the protected power is present in the device.

Bear in mind that Underwriters Laboratory (UL) requires all the devices to be self-testing from mid of 2015 onwards. The self-testing outlets can run a periodic test to ensure that the internal circuit is protected against any issues or neutral faults.

According to our assessment, Leviton GFNT1-W Self-test SmartlockPro Slim is the best GFCI outlet that you can buy at a very affordable price. The device comes with an added protective layer with which it consistently conducts an automated test to assure that it is capable of responding to a ground fault.

It is capable of detecting and tripping on any ground fault even if a self-test is in the process. Furthermore, the status indicator light also displays the protection and power status of the circuit along with the indication of a reversal of the load/line. These features make it the best GFCI outlet that you can buy in this price range.

So there you go, now you have all the information that you need to buy the best-suited GFCI outlet at a very comfortable rate. You can have a look at our buying guide if you have any questions associated with these devices and you can pick from one the products listed above by comparing their pros and cons.

So, happy shopping!
