We have our electric outdoor grill on an a GFCI outlet. Fairly often, when the grill is powering itself on and off to maintain the temperature, it will trip the breaker. Horrible design by the people who built this place as half the house is running on a single breaker (patio, living room, upstairs office, and dining room). Is the GFCI only there to protect in case of a short? And the breaker is tripping because of the spike from the grill turning on? Or should the GFCI be catching this before it trips the breaker?  

A GFCI will only trip in case of a "ground fault." If there's a difference in the currents between the lines, it trips. It will not trip when your circuit draws too much power and trips the breaker.

Understanding GFCI Nuisances

January 24, 2019

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.

What is a GFCI circuit Breaker?

A Ground Fault Circuit Interrupter (GFCI) circuit breaker is a special type of electrical protection device that serves the same purpose as a standard GFCI outlet but is installed at the circuit breaker panel rather than at individual outlets. It provides protection to an entire branch circuit and all the outlets connected to it.

A GFCI circuit breaker monitors the imbalance of electrical current between the hot and neutral wires within a circuit. If it detects a leakage of current, indicating a ground fault or a short circuit, it quickly interrupts the circuit, cutting off the power supply . This rapid response helps prevent electric shocks and electrical fires caused by ground faults.

GFCI circuit breakers are commonly used in locations where standard GFCI outlets might not be suitable or accessible, such as for large appliances or in areas where water is present, like kitchens, bathrooms, and outdoor spaces. They provide a reliable and centralized way to ensure electrical safety for multiple outlets or appliances connected to a single circuit.

Uses and Importance of GFCI Circuit Breaker

GFCI circuit breakers play a crucial role in maintaining electrical safety, particularly in areas where there is a higher risk of electrical hazards. Here are some of their uses and importance:

Protection from electric shocks: GFCI circuit breakers are vital in protecting individuals from electric shocks in areas where water is present, such as bathrooms, kitchens, laundry rooms, and outdoor spaces. They quickly interrupt the circuit when they detect an electrical fault, preventing potentially lethal shocks.

Prevention of electrical fires: By swiftly responding to ground faults and short circuits, GFCI circuit breakers help prevent electrical fires. They cut off the power supply when there is an imbalance in the electrical current, effectively minimizing the risk of overheating and fire.

Comprehensive circuit protection: Unlike individual GFCI outlets, GFCI circuit breakers offer protection to an entire branch circuit, safeguarding all the outlets and appliances connected to it. This comprehensive protection is especially crucial in areas where multiple outlets are in close proximity, such as kitchens and workshops.

Compliance with electrical codes: Many building codes now mandate the installation of GFCI protection in specific areas of a building. By using GFCI circuit breakers , builders and homeowners can ensure compliance with these safety regulations and standards, thereby reducing the risk of legal penalties and ensuring the safety of the occupants.

Ease of installation and maintenance: GFCI circuit breakers are relatively easy to install and maintain. They can be easily integrated into the existing electrical panel, providing a centralized and convenient solution for ensuring electrical safety. Additionally, they typically require less maintenance compared to individual GFCI outlets.

Versatility and adaptability: GFCI circuit breakers can be used in various settings, including both residential and commercial environments. Their versatility makes them an essential component in ensuring electrical safety in different types of buildings and structures.

Overall, the use of GFCI circuit breakers is instrumental in minimizing the risk of electrical hazards, protecting both individuals and property from potential electrical accidents and fires.

Their importance lies in their ability to provide comprehensive and reliable protection across entire electrical circuits, thereby ensuring the safety and well-being of occupants in a building.

How Does GFCI Circuit Breaker Work?

A Ground Fault Circuit Interrupter (GFCI) is a device designed to protect against electric shock. It works by quickly shutting off power to a circuit when it detects that the electric current is flowing along an unintended path, such as through water or a person. This quick response helps prevent serious injury or death from electric shock.

The working principle of a GFCI involves monitoring the flow of current along the hot and neutral wires of a circuit. It constantly compares the current flowing in the hot wire to the current flowing in the neutral wire.

If there is any imbalance between the two currents, it indicates that some of the current is taking an unintended path, possibly through a person or water, and the GFCI interrupts the power supply.

The basic components of a GFCI include a current transformer, a differential transformer, and a tripping mechanism. Here’s a simplified explanation of how it works:

Current transformer: The GFCI has a current transformer that constantly measures the current flowing through the hot and neutral wires. These measurements are compared to ensure they are equal.

Differential transformer: This transformer continuously compares the currents in the hot and neutral wires. If there is any imbalance, even as small as 4-5 milliamps, the differential transformer signals the tripping mechanism.

Tripping mechanism: Once the GFCI detects an imbalance, it quickly opens the circuit, cutting off the power supply in as little as 1/40th of a second. This rapid response prevents any potentially harmful electric shock.

GFCIs are commonly used in areas where there is a higher risk of electrical accidents, such as bathrooms, kitchens, and outdoor areas.

They are an important safety feature in modern electrical systems, providing an extra layer of protection against electric shocks and potential electrical fires.

Types of GFCIs

There are several types of Ground Fault Circuit Interrupters (GFCIs) designed to provide electrical safety in different applications. The most common types include:

Receptacle GFCI: These are the most familiar GFCIs and are designed to replace standard electrical outlets. Receptacle GFCIs are typically installed in wall outlets and provide protection for all devices plugged into them.

Circuit Breaker GFCI: These are GFCIs that are installed in the electrical panel or breaker box, providing protection to an entire circuit. They can be used in place of a standard circuit breaker and offer comprehensive protection to all outlets and devices on that specific circuit.

Portable GFCI: Portable GFCIs are designed as standalone devices that can be plugged into an existing electrical outlet. They are commonly used with tools and equipment that do not have built-in GFCI protection, such as power tools and extension cords. Portable GFCIs are often used in outdoor construction or when working in wet environments.

Cord-Connected GFCI: These are GFCIs integrated into extension cords. They are commonly used with outdoor power equipment like lawnmowers and string trimmers to ensure safety in wet or damp conditions. Cord-connected GFCIs are convenient for temporary applications and are portable.

Spa and Pool GFCI: These specialized GFCIs are designed for use with swimming pools, hot tubs, and spas. They are specifically tailored to the needs of these water-intensive environments, ensuring safety around the water.

Breaker-Style GFCI for Multiwire Circuits: These are GFCIs designed for use in multiwire branch circuits. They provide protection for both individual hot conductors in a multiwire circuit. In the event of a ground fault, they simultaneously interrupt both circuits to ensure safety.

Faceless (Dead-Front) GFCI: These GFCIs are designed without visible reset or test buttons on the front. They are often used in commercial and industrial settings where the GFCI protection is integral to the electrical system but shouldn’t be tampered with by personnel.

Combination GFCI/AFCI: Some GFCIs are integrated with Arc Fault Circuit Interrupter (AFCI) technology. These devices offer protection against ground faults as well as arc faults, which are a common cause of electrical fires. They are often used in bedrooms and other areas where AFCI protection is required by electrical codes.

The choice of GFCI type depends on the specific application and requirements. It’s essential to select the appropriate GFCI to ensure the safety of electrical circuits and to comply with local electrical codes and regulations.

Causes of GFCI Breaker Tripping

You’re about to uncover the secrets behind GFCI breaker tripping. Discover the common culprits and learn how to prevent it from happening in your electrical system. Let’s dive into the world of ground fault circuit interrupters and explore the reasons for their occasional misbehavior.

Fault Conditions

One of the main causes for GFCI breakers tripping is fault conditions in the electrical system. A ground fault occurs when an unintended connection is made between the hot and ground wires or the neutral and ground wires. This can cause an imbalance in current flow, causing the GFCI to trip. In my experience , moisture or water ingress into the receptacle box is a common reason for this type of fault 1 .

To prevent fault conditions, ensure that your electrical equipment and wiring is properly installed and maintained to keep out moisture and water. Also, make sure there are no loose connections or damaged insulation that could result in a ground fault.

Short Circuits

Short circuits are another leading cause of GFCI breaker tripping. When a direct connection is made between the hot and neutral wires, a short circuit can occur 2 . This massive surge of current can be dangerous, as it generates heat and can lead to fires.

To avoid short circuits, inspect your wiring for damaged insulation, loose or frayed connections, and any signs of overheating. By catching these issues early, you can prevent the short circuits that lead to GFCI breaker tripping.

While GFCI breakers are designed to protect you and your electrical system, understanding these common causes of tripping can help you prevent issues and maintain a safe, reliable setup. Remember to regularly inspect your electrical system and address any concerns to keep your home or office running smoothly .

When it comes to GFCI outlets, a handy little tool called a GFCI tester can make all the difference in ensuring your safety. These testers plug directly into the receptacle and simulate a ground fault to determine if the GFCI is functioning correctly.

To use a GFCI tester, just plug it into the outlet, press the “Test” button, and observe the outcome. If the GFCI works as it should, the tester will trip the GFCI, cutting off the power to the outlet. If the GFCI doesn’t trip as it should, it’s a clear indication that there might be a problem with the device. A thorough inspection of the wiring or replacement of the faulty GFCI will help prevent electrical hazards within your home.

Testing GFCI Circuit Breakers

In addition to GFCI outlets, GFCI circuit breakers are a crucial part of safeguarding your electrical system. These breakers combine the functionalities of both a GFCI and a traditional circuit breaker to detect ground faults and protect against overcurrent events.

Testing a GFCI circuit breaker is relatively simple. First, locate the breaker in your electrical panel and press the “Test” button on the breaker itself. If operating correctly, the breaker will trip immediately, indicating that it is functioning as intended. Should the breaker fail to trip, there might be an underlying issue requiring further investigation by a qualified electrician.

In my experience, regular testing of both GFCI outlets and circuit breakers is essential in maintaining a safe electrical environment. By taking a proactive approach and utilizing the appropriate testing methods, you can rest assured that your GFCI devices are protecting you from electrical mishaps and keeping your household secure. So, go ahead and test those GFCI devices – your peace of mind is worth it.

Ground Fault Circuit Interrupters (GFCIs):

[wpfa icon=”play-circle”] video

What is a GFCI

A ground fault circuit interrupter (GFCI) can help prevent electrocution. If a person’s body starts to receive a shock, the GFCI senses this and cuts off the power before he/she can get injured.

GFCIs are generally installed where electrical circuits may accidentally come into contact with water. They are most often found in kitchens, bath and laundry rooms, or even out-of-doors or in the garage where electric power tools might be used.

What is a ground fault?

According to the National Electrical Code, a “ground fault” is a conducting connection (whether intentional or accidental) between any electric conductor and any conducting material that is grounded or that may become grounded. Electricity always wants to find a path to the ground. In a ground fault, electricity has found a path to ground, but it is a path the electricity was never intended to be on, such as through a person’s body.

Because of this potential for shock, GFCI protection is used to protect human life.

How does a GFCI work?

The GFCI will “sense” the difference in the amount of electricity flowing into the circuit to that flowing out, even in amounts of current as small as 4 or 5 milliamps. The GFCI reacts quickly (less than one-tenth of a second) to trip or shut off the circuit.

What are the types of GFCIs?

There are three types of GFCIs. The most often used “receptacle-type” GFCI, similar to a common wall outlet, is the type with which most consumers are familiar. Additionally, circuit breaker GFCIs are often used as replacements for standard circuit breakers and provide GFCI protection to all receptacles on that individual circuit. Temporary or portable GFCIs are frequently used in construction and in outdoor settings with electric tools, mowers, trimmers, and similar devices. They should not be used as a permanent alternative to a regular GFCI. Temporary GFCIs should be tested prior to every use.

How should GFCIs be tested?

Many consumers don’t check their GFCIs to verify they are working. GFCIs are electronic devices that can be damaged or wear out. The electrical receptacle in a GFCI may continue to function, even if the GFCI circuit no longer works. If this is the case, have a qualified electrician replace it as soon as possible.

GFCIs should be tested monthly to ensure they are in working condition. Whether you have a receptacle or circuit breaker GFCI, pushing the TEST button should turn off the power to the circuit. For the receptacle-type GFCI, pushing the TEST button should cause the RESET button to pop up. (Remember to push the RESET button to re-establish power and protection.) For the circuit breaker-type GFCI, pushing the TEST button should cause the handle to move to the tripped position. (Remember to reset the handle to re-establish power and protection.)

When should you test GFCIs?

GFCIs should be checked monthly to determine if they are operating properly. A portable GFCI should be used out-of-doors with various electrical power tools (i.e., drills, mowers, trimmers) and should be tested before each use!

Where should GFCIs be used?

It is recommended that GFCIs be installed in areas where appliances and power tools are used in close proximity to water. Tap water or wet objects are able to conduct electricity very easily and can connect your body to a ground potential, thus increasing your chances of receiving a shock from a ground fault. Appliances that have built-in GFCI protection, as now required for hair dryers, may not need additional GFCI protection, but there are still many appliances not equipped with GFCI protection.

What is nuisance tripping of a GFCI?

It takes only 5 mA (0.005 A) of current leakage from the hot wire to the ground to cause a GFCI to trip. A small amount of leakage current may be difficult to avoid in some normal circuits. Hand-held power tools do not cause a tripping problem if the tool is maintained in good condition. Some stationary motors, such as a bathroom vent fan or fluorescent lighting fixtures, may produce enough leakage to cause nuisance tripping. Another problem may be a long circuit with many splices. If possible, keep GFCI circuits less than 100 feet long. To avoid nuisance tripping, a GFCI should not supply:

• Circuits longer than 100 feet
• Fluorescent or other types of electric-discharge lighting fixtures
• Permanently installed electric motors

How does a GFCI differ from an AFCI?

Arc fault circuit interrupters (AFCIs) are safety devices for homes that provide enhanced protection from fires caused by unsafe home wiring conditions.

AFCIs should not be confused with GFCIs. While both AFCIs and GFCIs are important safety devices, they have different functions. AFCIs are intended to address fire hazards; GFCIs address shock hazards.

A GFCI outlet is a type of electrical receptacle that protects against electric shock by interrupting the circuit when it detects a ground fault. The GFCI outlet constantly monitors the flow of electricity through the circuit and will trip when it senses that the current is flowing through an unintended path, such as through your body.

A GFCI outlet works by constantly monitoring the flow of electricity through the circuit. When the outlet detects an imbalance in the electrical current, it trips the circuit and shuts off the power. This rapid response helps prevent electric shock, making GFCI outlets essential safety devices in areas where water is present.

A bad breaker can cause a GFCI outlet to trip repeatedly. A breaker is responsible for interrupting the flow of electricity when there's an overload or short circuit. If the breaker is faulty, it may trip even when there's no overload or short circuit. This can cause the GFCI outlet to trip repeatedly, leaving you without power in the affected area.

If you suspect that a bad breaker is causing your GFCI outlet to trip, there are a few signs to look for. First, you may notice that the breaker trips frequently, even when there's no obvious cause.

Testing a GFCI outlet is a straightforward process. First, you'll need to locate the test and reset buttons on the outlet. Press the test button to simulate a ground fault. The outlet should trip and shut off the power. Next, press the reset button to restore power to the outlet. If the outlet doesn't trip when you press the test button, it may be faulty and need to be replaced.

Testing a circuit breaker is a bit more involved than testing a GFCI outlet. First, you'll need to shut off power to the circuit that the breaker is protecting. Then, you'll need to remove the cover from the breaker box and use a multimeter to test the breaker. Set the meter to read voltage and touch the probes to the two screws on the breaker. If the voltage reading is zero, the breaker is not working properly and needs to be replaced.

Replacing a bad circuit breaker is a job for a qualified electrician. To replace a breaker, you'll need to shut off power to the circuit and remove the cover from the breaker box. Then, you'll need to disconnect the wires from the old breaker and connect them to the new breaker. Finally, you'll need to snap the new breaker into place and replace the cover on the breaker box.

Replacing a GFCI outlet is a bit simpler than replacing a breaker, but it still requires some electrical know-how. To replace a GFCI outlet, you'll need to shut off power to the circuit and remove the cover from the outlet box. Then, you'll need to disconnect the wires from the old outlet and connect them to the new outlet. Finally, you'll need to mount the new outlet in the box and replace the cover.

If your GFCI outlet keeps tripping, there are a few things you can try to fix the issue. First, try resetting the outlet by pressing the reset button. If the outlet trips again, try unplugging any devices that are connected to the outlet and see if that solves the problem. If the outlet still trips, you may need to replace the outlet or the circuit breaker.

A GFCI outlet that keeps tripping can be a frustrating problem, but it's important to address the issue to ensure your safety. If you suspect that a bad breaker is causing your GFCI outlet to trip, it's essential to have the problem fixed by a qualified electrician.

Does a GFCI trip if you overload the circuit?

Thursday, July 15, 2021

A GFCI ( G round F ault C ircuit I nterrupter) device only trips when there is a difference between the amount of current leaving it and the amount returning to it. This current leakage indicates that a person might be getting shocked, and it trips within a fraction of a second. So a GFCI receptacle outlet does not trip due to an overloaded circuit. 

    A GFCI breaker in a panel will trip, however, because it combines both overcurrent and GFCI protection in one device—and the overcurrent protection part will cause it to trip.

GFCI Receptacle vs. GFCI Circuit Breaker

When to Use Receptacles or Breakers for Electrical Safety

What Is a GFCI Receptacle?

What is a gfci circuit breaker, when to choose a gfci receptacle, when to choose a gfci circuit breaker.

Users can be protected from ground fault shocks in two ways: with a GFCI receptacle or a GFCI circuit breaker.

A GFCI receptacle protects the user at the device itself, such as an outlet in a bathroom or kitchen. A GFCI breaker protects all devices connected to the circuit. Making the correct choice requires that you weigh the various advantages and disadvantages of each.

Your local electrical code may have specific requirements for how to provide GFCI protection in your area.

A GFCI receptacle is integrated into an electrical outlet and it typically has a red (or possibly white) reset button on the outlet's faceplate.

If the receptacle detects an electrical overload or imbalance, it trips off the circuit in a fraction of a second, and the small reset button pops, indicating that the electricity is no longer flowing.

GFCI receptacles are generally used instead of standard outlet receptacles to protect a single outlet location.

GFCI receptacles , while usually wired to protect one device, can be wired to protect multiple devices. Multiple-location wiring protects the first GFCI receptacle and every receptacle downstream of it (including standard receptacles) in the same circuit. However, it does not protect the portion of the circuit upstream, between itself and the main service panel.

A GFCI circuit breaker , installed in one of the service panel (breaker box) slots, adds GFCI protection to the entire circuit.

GFCI circuit breakers make more practical sense in situations where all outlets on a circuit require GFCI protection .

GFCI breakers can be expensive, though, so this is not always the more economical option. Plus, it's not always the most DIY-friendly option for homeowners uncomfortable working on circuit breaker panels.

• Single-point protection : If you only need to protect one device, it's best to use a GFCI receptacle than a GFCI breaker, which protects multiple devices.
• Simple installation: GFCI receptacles are easier to install than GFCI breakers. If you're a DIYer unfamiliar with working on a service panel, installing a receptacle is more straightforward and safer than replacing a circuit breaker.
• Local resetting: When a GFCI receptacle trips, you can reset it locally at the receptacle location rather than going to the circuit breaker panel.
• Cost: A GFCI receptacle costs around $15. So, if money is an issue, a GFCI outlet will be a better choice than a GFCI breaker.
• Multiple-point protection: If you need GFCI protection in several locations, it makes the most sense to simply install one GFCI breaker to serve all of those locations at once.
• Easier resetting: In some cases, it can be easier to reset a circuit breaker than a GFCI receptacle. The National Electrical Code (NEC) requires that GFCI receptacles be in readily accessible locations, ensuring easy access for resetting the receptacle if it trips. So, if any GFCI receptacles are difficult to access (such as behind furniture or appliances), it's actually easier to reset a GFCI breaker.
• Economy of size: GFCI receptacles are large and bulky. With standard-size boxes, there may not be enough room to add a GFCI receptacle safely. So, using a GFCI circuit breaker allows you to install slimmer regular outlets in the boxes.
• Electrical code: The local electrical code may have particular GFCI requirements that require the use of a GFCI breaker.

A GFCI breaker will trip when too many devices are overloading the circuit or when an appliance has caused a ground fault.

It is unnecessary to install a GFCI breaker and GFCI outlet on the same circuit. This type of double protection may make an electrical system behave erratically and unpredictably.

Installing a GFCI on every outlet is unnecessary. Avoid using GFCI for lights because if the circuit trips, you will be in the dark. In addition, GFCI outlets are really only meant for areas where electricity and water may come into contact by accident.

How to Fix a Tripped Hot Tub GFCI Circuit Breaker

Finally, you're the owner of the hot tub you've always wanted. Ever since you first brought it home, it's provided you with nothing but peace, relaxation, and comfort. Except for one small thing: The GFCI circuit breaker keeps tripping, shutting off the power to your spa just when you're settling in for a soak.

GFCI issues are a relatively common occurrence with hot tubs, and often can be resolved with little fuss or expense. However, because electricity and water are an extremely dangerous combination, make sure you know what you're doing before troubleshooting any electrical problems. Unless you're confident in your ability to address GFCI issues yourself, always consult a professional hot tub repair expert or electrician. An improperly-wired hot tub can result in electrocution or an electrical fire. Electrical work such as installing a hot tub or making adjustments to its components or wiring must be performed by a licensed electrician and must adhere to all local and national electrical codes. As a reminder, always turn off your hot tub and disconnect it from the power supply before attempting any repairs.

What is a GFCI circuit breaker?

A GFCI—a Ground Fault Circuit Interrupter—is a device used to protect your hot tub from unusual fluctuations or deviations in your power supply. Ground faults and short circuits occur when electricity takes a path the designers of the circuit didn't intend. When a GFCI detects an anomaly in the electrical supply, such as a ground fault or a short circuit, it interrupts the circuit and cuts off all electricity to your spa. When this interruption occurs, it's often referred to as “tripping” the GFCI.

WHERE IS MY GFCI?

Even if you've never experienced any electrical problems with your hot tub, make sure you know where your GFCI is located. While some hot tubs are designed to plug into a traditional 120-volt outlet, most will require the installation of both a GFCI circuit breaker and a dedicated electrical outlet designed to handle the increased voltage—generally 220 to 240 volts—necessary to power your spa. Most likely, you'll find your GFCI in the control panel located close to or containing the outlet your spa or hot tub uses. To reduce the risk of the electrical supply coming in contact with water, the National Electrical Code requires that the electrical components, including the GFCI, be located a minimum of six feet away from your hot tub.

HOW DO I RESET MY GFCI?

Your GFCI should have a visible reset button. These buttons are usually red and are clearly labeled “reset.” To reset your GFCI, simply press the button. This will restore the electricity supply to your spa.

WHY DOES MY GFCI KEEP TRIPPING WHEN I TURN ON MY HOT TUB?

When your GFCI trips, it's an indication that something unexpected has happened with your electrical supply. This might be a one-time occurrence, which may be resolved by simply pressing the button to reset the breaker. If your GFCI repeatedly trips whenever you turn on your hot tub, it means there's an ongoing problem that must be addressed and resolved. There are a few reasons why your GFCI might trip each time you power up your hot tub:

• There may be an issue with your GFCI. Disconnect all hot tub components from your GFCI, then reset it. If it immediately trips even though nothing is attached to it, your GFCI is most likely faulty and will need to be replaced.
• There may be an issue with one of your hot tub's components, such as the heater, the pumps, or the entertainment system. If these components can be individually disconnected from your GFCI, disconnect them all, then reconnect and test them one at a time. If any of them cause your GFCI to trip when you turn your hot tub on, the faulty component will most likely need to be serviced or replaced.
• Your GFCI may be wired incorrectly. To isolate a faulty switch or wire, disconnect wires one at a time to each switch, then test the GFCI to see if any individual wire causes it to trip.

Once again, it's important to stress that electricity can be harmful or fatal. If you aren't confident in your ability to safely troubleshoot electrical problems, call in a knowledgeable and experienced professional.

WHY DOES MY GFCI TRIP AT RANDOM TIMES?

Your GFCI may trip at seemingly random intervals, either while you're in the middle of a soak or when your hot tub is not in use. If your GFCI constantly trips, one of the following issues might be the culprit:

• Your hot tub heater may be corroded or otherwise damaged. Problems with the heating elements are among the most common causes of GFCI issues. Inspect your heater for visible signs of damage, and try operating your hot tub with the heater disconnected to see if the GFCI problem reoccurs.
• Your spa's electrical contacts have become corroded. Inspect each contact and replace any that show signs of corrosion.
• One or more electrical connections is loose. With the power to your spa disconnected, tug gently on each connection, then tighten and secure any that seem to be loose.
• The control box containing your GFCI has been exposed to moisture, such as rainwater or condensation. If the inside of your control box is damp, locate the source of the moisture, protect your box from future water exposure, and allow it to thoroughly dry out before testing the GFCI. If water has damaged any electrical components, replace them.
• There's a short in one or more of your electric components. Run your spa for 15 minutes, then turn it off, unplug your tub, and inspect your components by hand. Electrical components that are shorting out will feel warm to the touch. Replace any components which grew warm during your test.

WHERE CAN I FIND REPLACEMENT COMPONENTS OR GFCIS?

Your local hardware store will likely have replacement GFCIs and components for sale, or you can order them online. If you're not certain which model or configuration to purchase, talk to a repair professional or licensed electrician. The best way to find components for your hot tub is often by visiting the dealer who sold it to you . They will have advanced knowledge of your specific model and will either have parts in stock, or will be able to order them for you. They'll also have experience diagnosing and repairing similar problems and may be able to offer repair services or advice.

A GFCI circuit breaker that trips constantly is at best a nuisance, and could be an indication of a potentially hazardous situation with your hot tub. Armed with a little knowledge, you should be able to diagnose the problem with your GFCI and find a way to fix it, either by repairing it yourself or by calling upon the knowledge and services of your hot tub dealer or a licensed electrician. A tripped GFCI can be frustrating, but it doesn't have to get in the way of your enjoyment of your hot tub.
