Ground Fault Circuit device designed interrupt current circuit ground
Interrupter (GFCI) fault sensed. Renewable fuses allow the user replace the link
and non-renewable fuses not. Ground faults can endanger people and damage
equipment. For this reason, some circuits are equipped with a
ground fault circuit interrupter (GFCI). GFCI
circuit breaker combines protection for ground faults, overloads,
and short circuits one device
