WebProtective devices capable of responding to overloads and short circuit, such as circuit breakers, have been available for a number of years. Newer technologies now provide enhanced protection from arcing or ground-faults, which may prevent fires or shock. WebApr 5, 2024 · A Class A Ground Fault Circuit Interrupter (GFCI) works by detecting any loss of electrical current in a circuit (e.g., it will trip at a maximum of 6mA). When a loss is detected, the GFCI turns the electricity off before severe injuries or electrocution can occur. WebGFCI and AFCI Information. The Ground Fault Circuit Interrupter or GFCI and Arc Fault Circuit Interrupter or AFCI are two different electrical devices that serve distinct purposes. A GFCI is designed to prevent electrical shock and is typically in damp and outdoor locations. The AFCI is designed to prevent fires and is usually on bedroom circuits. ronaldinho facts
