Where should you not use GFCI
Residual-current device
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock.
Do I need a GFCI on every outlet?
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.
Do I need a GFCI circuit breaker?
Spiderstock/Getty Images. GFCI (ground-fault circuit interrupter) protection is required for many outlet receptacles throughout the house and in outdoor locations. This protection can be provided either by a GFCI circuit breaker or GFCI receptacles.
What happens if you bypass a GFCI?
If you bypass the GFCI circuit and the current detects an imbalance, it will immediately shut off which can produce an electric shock. Although not required by law, using a GFCI as well as a dedicated circuit, will help cut down on any risks of shock.
What does it mean when a GFCI trip?
The GFCI is very sensitive and can detect a difference in the current of a few milliamps. The typical circuit breaker will trip when amperage levels exceed its ratings, usually 15 or 20 amps for home use. This is to prevent the circuit from overheating and causing a fire, though this doesn’t protect against shocks and electrocution.

What happens if a GFCI trips frequently?
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.
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.
How much does a GFCI outlet cost?
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.
What is the purpose of a GFCI outlet?
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:
How to shut off power to outlet?
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.
What happens when a ground fault occurs?
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.
Where is GFCI protection required?
This protection is generally required wherever an outlet is in proximity to the earth or to water sources that can create a direct path to earth. This required protection can be provided either by a GFCI circuit breaker or GFCI receptacles.
What is GFCI protection?
Email. The Spruce. The National Electric Code (NEC) and all local building codes require GFCI (ground-fault circuit interrupter) protection for many outlet receptacles throughout the house and in outdoor locations. The requirements exist to protect users against the possibility of shock in the event of a ground fault, ...
What Is a GFCI Receptacle?
You can tell if a receptacle is a GFCI one or not by the way it looks. The GFCI is integrated into an electrical outlet and it typically has a red (or possibly white) reset button on the outlet's faceplate. The outlet monitors how much energy is going into it when in use. If the receptacle senses any sort of an electrical overload or imbalance, it is designed to trip the circuit in a fraction of a second.
How much does a GFCI breaker cost?
A GFCI receptacle often costs around $15. A GFCI breaker might cost you $40 or $50, versus $4 to $6 for a standard breaker. If money is an issue and you only need to protect a single location, a GFCI outlet might a better choice than a GFCI breaker. Finally, there's the local electrical code, which may have particular GFCI requirements ...
Why use a GFCI breaker?
For example, let's say you're adding a receptacle circuit for a garage workshop or a large outdoor patio space. Because all of these receptacles require GFCI protection, it is probably more efficient to wire the circuit with a GFCI breaker so that everything on the circuit is protected.
When to choose a GFCI receptacle over a GFCI breaker?
When to Choose a GFCI Receptacle Over a GFCI Circuit Breaker. When a GFCI breaker trips, you must go to the service panel to reset it. When a GFCI receptacle trips, you must be able to reset it at the receptacle location. The National Electrical Code (NEC) requires that GFCI receptacles must be in readily accessible locations, ...
Is a GFCI receptacle bigger than a standard receptacle?
With standard-size boxes, there may not be enough room to add a GFCI receptacle safely, making a GFCI circuit breaker the better choice.
Where should GFCI be located?
GFCI protection should be located in any place where there is moisture, as moisture greatly increases the risk of accidental shock . In buildings that follow proper electrical codes, you will commonly find GFCI outlets in a number of places: Bathrooms. Garages. Exterior Electrical Receptacles. Crawl Spaces.
What is a GFCI circuit interrupter?
A GFCI, or Ground-Fault Circuit-Interrupter, is a device that protects you from receiving electrical shocks from faults in electrical devices. Since being introduced into the 1971 National Electrical Code, the number of electrocutions in America has dropped dramatically. The way it works is by comparing the input current on the hot side to ...
Why does a GFCI circuit breaker trip?
This is to prevent the circuit from overheating and causing a fire, though this doesn’t protect against shocks and electrocution.
Why is my refrigerator tripping?
If your refrigerator is tripping your GFCI circuit, it is often the result of a faulty refrigerator and not the circuit itself. Other than that rare situation, the benefits of using GFCI far outweigh the negatives. If the water lines feeding your refrigerator break, the water will pool on the ground and could come into contact with electrical ...
What are the requirements for a refrigerator?
There has been little change to the 2011 version of the NEC guidelines regarding refrigerators and GFCI. The information provided under NEC Article 210.8 and 210.52 is as follows: 1 All commercial buildings/kitchens are required to have GFCI for refrigerators. 2 In a Dwelling Unit (house or apartment) refrigerators located inside the kitchen do NOT have to have a GFCI. 3 If the circuit feeding the refrigerator outlet is branched to any other outlet, it must be a 20-A circuit. If the circuit feeding the refrigerator outlet is a dedicated individual circuit, then it can be either 15-A or 20-A. 4 In a garage or an unfinished basement of a Dwelling unit, the refrigerator must have a GFCI circuit.
How to eliminate risk of microwave?
One way to eliminate that risk is to use a dedicated circuit for the refrigerator. If the circuit that the microwave, toaster, and coffee maker are on trip, the damage is not as severe as if all your food spoils
Why use a dedicated circuit in a refrigerator?
As a way to safeguard this and protect your food , a dedicated circuit is often used when it comes to powering refrigerators.
How far does an AFCI extend?
Exception: AFCI protection shall not be required where the extension of the existing conductors is not more than 1.8 m (6 ft) and does not include any additional outlets or devices.
How many exceptions are there to the NEC?
According to @Tester101's answer (drawing from the 2014 NEC) there are two exceptions.
What is the code for snowmelting receptacles?
Receptacles that are not readily accessible and are supplied by a branch circuit dedicated to electric snow-melting, deicing, or pipeline and vessel heating equipment shall be permitted to be installed in accordance with 426.28 or 427.22, as applicable.
Does a GFCI measure ground leakage?
A GFCI device doesn't generally measure leakage to ground, it compares the current on the hot leg to the current on the neutral leg. Normally the same amount of current should go out as comes back. The premise is, if more current is seen on the hot than the neutral, it is assumed that some current is leaking to ground rather than returning on the neutral - which could mean someone is getting electrocuted - so the device interrupts the current.
Can a GFCI trip a motor?
GFCIs will often nuisance trip with certain types of loads. For example many motors will trip the GFCI even though there is no leakage to ground. This is why there is an exception for the refrigerator's outlet. It's a good idea to have that on a circuit of it's own with no GFCI.
Can a receptacle be installed without GFCI?
In industrial laboratories, receptacles used to supply equipment where removal of power would introduce a greater hazard shall be permitted to be installed without GFCI protection.
