Locate the circuit breaker or fuse that controls the outlet you plan to replace and shut off the power to the circuit. Plug a lamp, radio or the GFCI tester into the outlet to test for power and ...

The typical GFCI outlet cost ranges from $130 to $300, with a national average of $210 for this type of outlet installation.

To replace an existing receptacle with a GFCI receptacle, start by cutting the power to the circuit in which you want to install the GFCI replacement receptacle.

GFCI devices add a lot of life safety for a small price; usually $10 - $15 for a GFCI outlet, plus a little bit of work that I consider to be a good "starter" electrical project.

Outlets and breakers with GFCI, which stands for ground fault circuit interrupter, monitor current flow on the ungrounded (the hot) and the grounded conductor (the neutral).

There could be a tragedy waiting to happen if you haven’t tested your home’s Ground Fault Circuit Interrupters recently. Commonly referred to as GFCIs, these are the electrical outlets … ...

Note: This article is based on the 1999 NEC. Since 1971, the NEC has expanded the requirements for ground-fault circuit interrupters (GFCI) to protect anyone who plugs into an electrical system.

That means if the downstream outlet is presented with a condition that would cause a GFCI to trip and open the circuit, cutting off power, then the GFCI through which the outlet is wired will trip.

Currently, all 15 and 20 amp, 125 volt, single phase receptacles located in residential garages and unfinished basements would require GFCI Protection for Personnel. Typically, appliances or ...
