  • Why Is GFCI Protection Important For Electrical Safety

    A ground-fault circuit interrupter (GFCI) is a fast-acting circuit breaker which can detect small imbalances in the circuit caused by current leakage to the ground and turn off the electricity at a fraction of a second. The GFCI outlet matches the amount of current that is going into an electrical device against the amount of current returning
