Fault earthing, also known as ground fault, is the accidental connection of the conductor to the earth. AGroundFaultCircuitInterrupter (GFCI) is a new type of circuit breaker that can prevent damage to house wiring and protect people from electric shock. The GFCI constantly monitors the current on the neutral and live wires in the circuit. When all is well, the current should be exactly the same o...
