Gfci switch

Where GFCIs Are Required. 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.

What is the purpose of GFCI?

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.

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.

How does a GFCI light switch work?

The GFCI can sense the current flowing through you because not all of the current is flowing from hot to neutral as it expects -- some of it is flowing through you to the ground. As soon as the GFCI senses this "leakage" of power, it trips the circuit and cuts off the electricity.

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.

How do I know if I need a 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.

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.

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.

Why does GFCI trip when power goes out?

Gfci receptacles don't provide overload protection, only ground fault protection. Gfci breakers could trip if overloaded and you wouldn't know the difference. If over the amps on the circuit, the breaker will trip not the gfci receptacle.

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.

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.

How long do GFCI switches last?

Electrical safety check All GFCI outlets have one little-known flaw: their circuitry eventually wears out, usually after about 10 years, at which point they no longer function properly.

How do you control a GFCI switch?

How do I wire a switch to control a GFCI Receptacle?

Place the switch in the hot wire going to the "line" side of the GFCI outlet.
Run the neutral wire uninterrupted to the "line" side of the GFCI outlet.
Connect ground wires as usual, switch and outlet.

How do you reset a GFCI switch?

Outlet is working correctly to start plug in a small lamp or light and turn it on. Next press the

Will a GFCI trip if you touch it?

If the GFCI is properly in- stalled, it will trip as soon as a faulty tool is plugged in. If the grounding conductor is not intact or of low-impedance, it may not trip until you touch it and provide a path. If this occurs, you will receive a shock, but should not be harmed because of the speed at which the GFCI trips.

Can I put a GFCI outlet anywhere in a circuit?

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.

Can you still get electrocuted with GFCI?

Remember, contrary to popular belief, you can be electrocuted on a GFCI-protected receptacle. GFCIs only detect imbalances in the current between the hot and the neutral. They cannot tell if the power is lighting up the light bulb or you.

Is it better to use a 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 often should GFCI outlets be replaced?

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.
