Gfci also known as ground fault circuit interrupter is a protective device which automatically detects the ground faults and leakage current and provides personal protection against electrocution. There are two different kinds for home use electrical outlets and circuit breakers.

Wiring Diagram Gfci Circuit Ground Fault Circuit
Gfci circuit diagram. Gfci as an outlet receptacle combo or circuit breaker automatically cuts off the main power supply within millisecond against electric shock. Read on to learn more about proper installation. So gfci designed as checking the difference between the current leaving and returning through current transformer of the gfci to protect device exceeds 5ma.

The load terminals on the gfci are not used and the last receptacle is wired directly to the circuit source.
This diagram illustrates the wiring for multiple ground fault circuit interrupter receptacles with an unprotected duplex receptacle at the end of the circuit. In the gfci mainly two wires connect as also shown in a diagram the current flowing from the source and coming back are some due to current laws. The line terminals of a gfci outlet connect to the power supply conductors that are connect at the circuit breaker or fuse box.
