What Is A Ground Fault Circuit Interrupter

A GFCI constantly monitors current flowing through a circuit. If the current flowing into the circuit differs by a very small amount (as little as 0.006 amperes) from the returning current, the GFCI interrupts power faster than a blink of an eye to prevent a lethal dose of electricity.

What is ground fault circuit interrupter in simple words?

A Ground Fault Circuit Interrupter (GFCI) is an automatic electrical circuit breaking safety device for protection against line-to ground faults. A GFCI offers protection to users of electrical equipment against possible fatal electrical shock from faulty equipment or accidental grounding.

When should ground fault circuit interrupters be used?

A GFCI should be used in any indoor or outdoor area where water may come into contact with electrical products. The National Electrical Code currently requires that GFCIs be used in all kitchens, bathrooms, garages, and outdoors.

What is a ground fault interrupter circuit and why is it important?

Ground-fault circuit interrupters (GFCIs) are used for protection from an electrical ground fault. They will also protect against fires and overheating. A GFCI is a fast-acting circuit breaker designed to turn off electric power in the event of a ground fault.

What should you not plug into a GFCI?

But don't plug big appliances such as refrigerators, freezers and sump pumps into a a GFCI outlet or circuit. It's also not a good idea to put lights on GFCI circuit – you don't want to be left in the dark if the circuit trips.

Why does GFCI trip when power goes out?

GFCI breakers, or ground fault circuit interrupters, trip if the current on the load wire is more than marginally greater than the return wire. This is done with the understanding that the electricity has to go somewhere, so if it's not being returned, it is likely hurting something or someone.

Do all bathroom outlets need to be GFCI?

GFCI receptacles are required in bathrooms, garages, crawl spaces, basements, laundry rooms and areas where a water source is present.

How do I know if my outlet is GFCI?

A GFCI receptacle is easily recognizable. Simply look for the test and reset button on the face of the outlet. When installed, any electrical device that is plugged in will be protected in the case of a ground fault. This also includes any electrical outlets that are connected on the same line.

Where do you need GFCI outlets?

GFCIs are required by the National Electric Code (NEC) in all kitchens, bathrooms, crawl spaces, unfinished basements, garages, and outdoor receptacle locations. Outdoor outlets also require special boxes and covers.

Can you replace a regular outlet with a GFCI outlet?

A GFCI (ground fault circuit interrupter) is a special type of outlet that detects dangerous ground faults and immediately turns off the power to stop shocks. You can replace almost any electrical outlet with a GFCI outlet. Correctly wired GFCIs will also protect other outlets on the same circuit.

What are the 3 places in the house that must have GFCI?

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.

Can I install a GFCI outlet myself?

Materials you will need for this DIY project: You'll need: A new GFCI outlet and outlet plate. A flat head screwdriver, for removing the outlet plate and old electrical outlet. A Phillips screwdriver, for replacing the GFCI outlet, and tightening the connections.

How many outlets can a GFCI protect?

There's no limit. A standard GFCI will protect up to 20 amps, drawn from any combination of receptacles, either the built-in one or any number of additional ones connected to its load terminals.

Do all kitchen outlets need to be GFCI?

Not all your kitchen outlets need to be the GFCIs, but they are required to be if they're within six feet of a kitchen sink or if they serve a countertop. Near laundry room sinks. Any receptacles within 6 feet of a sink or washing machine should be GFCIs.

Do all outdoor outlets have to be GFCI?

Plus, the National Electrical Code requires all outdoor outlets to be GFCI outlets (ground fault circuit interrupter outlets). GFCI outlets trip and turn off automatically when there's a current leakage or short circuit, which helps prevent fires and accidental shocks.

What's the difference between a GFI and a GFCI?

Ground fault circuit interrupters (GFCI) and ground fault interrupters (GFI) are the exact same device under slightly different names. Though GFCI is more commonly used than GFI, the terms are interchangeable.

Will an extension cord trip a GFCI?

The GFCI receptacle should be unaffected by a 50' extension cord of that large gauge. not much difference than using the load terminals on a GFCI circuit.

Which is better GFCI outlet or breaker?

GFCI breakers offer complete protection of every outlet in a circuit, while GFCI receptacles protect ordinary receptacles or outlets. They can be single-location or multi-location GFCI receptacles, which manage to protect other downstream outlets. Expect to save more on initial costs when you opt for a GFCI receptacle.

How long does a GFCI outlet last?

GFCI outlets last between 7-10 years but can sometimes fail after only 5 years. Since GFCIs are one of the most important safety features in your home, it's important to check your GFCIs monthly and every home should have its GFCIs tested and replaced if necessary every 7-10 years.

Can a ground fault cause a fire?

Ground faults can lead to disastrous results such as electrical shock, fire, or burns.
