Can you use a GFCI receptacle in a half-switched box?
Some receptacles are configured to be "switched" and there may be "extra" wires in the box for that function. If the receptacle is intended to be "half-switched", meaning one outlet is switched and the other is not, you cannot use an ordinary GFCI receptacle in that location.
Can you wire a GFCI outlet?
Never wire a GFCI outlet where an item with a motor, like an appliance, is connected. The momentary electrical surge when a motor starts can cause the breaker to trip. It is fine in a bathroom, since hair dryers and shavers do not draw a lot of current.
Does a GFCI need a ground wire?
Top Answerer. A GFCI without a grounding wire will not provide "ground," but the mechanism to trigger upon a "ground fault" will work because it does not involve the ground wire - it only measures the current to and from the hot and neutral wires to make sure they are identical. Thanks!

What is a GFCI circuit?
Almost everyone has heard of a GFCI (Ground Fault Circuit Interrupter ). These devices precisely monitor the balance of electrical current moving through a circuit and immediately cut off the electricity when a short occurs. For more on the basics of a GFCI see our article on Ground Fault Interrupter Circuits. Wiring a GFCI may vary slightly from manufacturer to manufacturer, but for the most part they follow the same general principles. We’ll try to simply and succinctly outline those below so that you understand how to correctly connect a GFCI into your electrical circuit and provide protection for an outlet or series of outlets and fixtures.

What is ground fault?
A ground-fault occurs when there is a break in the low-resistance grounding path from a tool or electrical system. The electrical current may then take an alternative path to the ground through the user, resulting in serious injuries or death. The ground-fault circuit interrupter, or GFCI, is a fast-acting circuit breaker designed to shut ...
Does GFCI protect against ground fault?
The GFCI will not protect you from line contact hazards (i.e. a person holding two "hot" wires, a hot and a neutral wire in each hand, or contacting an overhead power line). However, it protects against the most common form of electrical shock hazard, the ground-fault. It also protects against fires, overheating, and destruction of wire insulation.
Can a GFCI trip?
The GFCI is rated to trip quickly enough to prevent an electrical incident. If it is properly installed and maintained, this will happen as soon as the faulty tool is plugged in. If the grounding conductor is not intact or of low-impedance, the GFCI may not trip until a person provides a path.
