GROUND FAULT CIRCUIT INTERRUPTER (GFCI) RECEPTACLE
The ground-fault circuit interrupter will not protect against short
circuits or overloads. The circuit breaker in the control panel that
supplies power to the circuit provides that protection (refer to circuit
breaker on page ).
The ground fault circuit interrupter can be identified by the TEST and
RESET buttons. The duplex receptacle on the GFCI can be tested with
the TEST and RESET buttons.
The 20-ampere, 120-volt duplex receptacle that has TEST and RESET
buttons is protected by a Ground Fault Circuit Interrupter (GFCI)
against the hazards of ground fault currents. An example of ground
fault current is the current which would flow through a person who is
using an appliance with faulty insulation and, at the same time, is in
contact with an electrical ground such as a plumbing fixture, wet floor,
or earth.
