A residual current device RCD (similar to a residual current circuit breaker RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance is sometimes caused by current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. RCDs are designed to disconnect quickly enough to mitigate the harm caused by such shocks although they are not
intended to provide protection against overload or short
