How does a GFCI receptacle work?
GFCI outlets and breakers have a sensor that detects electrical imbalances as low as 4 to 5 milliamps across the hot and neutral wires. When an imbalance occurs, the sensor instantly breaks the circuit rendering the circuit dead. Power can be restored by resetting the tripped outlet or breaker.
