A ground fault circuit interrupter, called a GFCI or GFI, is an inexpensive electrical device that can either be installed in your electrical system or built into a power cord to protect you from severe electrical shocks. GFCIs have played a key role in reducing electrocutions.

What are the 3 types of GFCI?

Three types of GFCIs are commonly used in homes – the GFCI outlet, the GFI circuit breaker and the portable GFCI.

Is an RCD the same as a GFCI?

A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that quickly breaks an electrical circuit with leakage current to ground. It is to protect equipment and to reduce the risk of serious harm from an ongoing electric shock.

What is 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.

When should a GFCI be used?

GFCI protection is required for 125-volt to 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to the ground. GFCI receptacles are required in bathrooms, garages, crawl spaces, basements, laundry rooms and areas where a water source is present.

Why does GFCI keep tripping?

If the GFCI's internal current transformer senses more than a 4-5 milliamp loss, it instantly shuts down the outlet and any outlets it feeds to prevent accidental electrocution. Most often, when a GFCI “trips” it is the result of a faulty appliance plugged into the outlet or an outlet down circuit.

Does a GFCI need its own breaker?

But a GFCI does not need its own breaker. It can share a breaker with other non-GFCI circuits.

Can I replace a GFCI with a regular outlet?

GFCI's can wear out. If you're willing to give up the protection then yes, you can switch back to a normal grounded outlet and the wiring should be basically the same. You'll need a new face plate, of course, unless you get a duplex that has the same rectangular outline.

Can a GFCI go anywhere in the circuit?

Yes, a single GFCI (Ground Fault Circuit Interrupter) receptacle outlet will protect everything on the circuit, but ONLY if it is placed at the first outlet location. If it is installed anywhere else, then it will protect everything downstream, but not any outlets between the GFCI and the panel.

Do I need GFCI on all outlets?

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 all GFCI outlets have a reset button?

All GFCI outlets have a reset button (typically red) in the upper center of the outlet. Find the GFCI outlet near the outlet that tripped. You will be able to tell the problem outlet because the red reset button will have popped out.

Is it better to use a GFCI outlet or breaker?

If you want to protect your entire electrical system from ground faults, then GFCI circuit breakers are the best choice. However, if you only need to protect individual outlets, then GFCI receptacles are a better option.

Where should you not use GFCI?

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 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.

Where would a GFCI need to be installed?

GFCI outlets should be installed in any potentially wet or damp areas such as kitchens, bathrooms, laundry rooms, outdoors, basements, garages and workshops.

How do I stop my GFCI from tripping?

Plug in one appliance at a time until the GFCI trips. Make sure to turn on each appliance as you plug it in. The last appliance you plug in/turn on likely has a ground fault (that is, it's leaking electricity) or all your appliances in combination are overloading the circuit.

How can I tell if a GFCI outlet is bad?

If the GFCI won't reset or the button doesn't pop out when you press the "test" button, there may be no power to the GFCI or you may have a bad GFCI. Pro tip: If the "reset" button trips again every time you press it, there may be a dangerous current leak somewhere on the circuit.

Will a GFCI trip if wired wrong?

If you miswired the GFCI it may not prevent personal injury or death due to a ground fault (electrical shock). If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.

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.

Can you have 2 GFCI outlets on the same circuit?

You may use two or more GFCI rated outlets on one circuit if you like. However, if one trips or goes bad, all the outlets/GFCIs down the line will be affected. That's why you should test your GFCI's monthly to ensure proper operation.
