Best Answer: A. GFCI is the correct answer. Ground Fault Circuit Interruptor: This will open the circuit when a difference in current is detected between the hot and neutral wires in a 120VAC (House current) circuit. B Circuit Breaker will only open the circuit on the hot side when a maximum current is reached. C. Blows open when a maximum current is reached in one line.
A residual current device (RCD) is a safety devicethat switches off electricity automatically if thereis a fault. RCDs are far more sensitive thannormal fuses and circuit-breakers and provideadditional protection against electric shock.Additional protection by means of an RCD canbe a lifesaver.An RCD constantly monitors theelectric current flowing along a circuit.n appliance can then be plugged intothe RCD. These are useful when neither fixed norsocket-outlet RCDs are available, but again theyprovide protection only to the person in contactwith the equipment, including the leads,plugged into the portable RCD.
