RCD=RCCB=ELCB, 都係漏電斷路器 .
RCD = Residual Current Device = 剩余電流裝置
RCCB = Residual Current Circuit Breaker = 剩余電流斷路器
ELCB = Earth Leakage Circuit Breaker = 漏電斷路器
MCB+RCD = RCBO 漏電+過載 斷路器
RCBO = Residual current operated circuit breaker with integral overcurrent protection
A residual current device (RCD) is similar to that of a residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the phase ("hot") conductor and the 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.
