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.
