A GFCI is a ground fault circuit interrupter which is an inexpensive electrical device that constantly monitors electricity flowing in a circuit to sense any loss of current. If a loss is detected, the GFCI quickly switches off power to that circuit.  GFCIs can prevent over 2/3 of the approximately 300 electrocutions still occurring each year in and around the home. Installation of the device can also prevent thousands of burns and electric shock injuries each year.

In order to comply with National Electric Code, GFCI protection is required for most outdoor receptacles, bathroom and kitchen receptacles, garage wall outlets and all receptacles in crawl spaces and unfinished basements.  For homes protected by fuses, installation of GFCIs are limited to receptacle or portable-type GFCIs which can be placed in areas of greatest exposure such as the bathroom, kitchen, basement and garage.
