An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use residual-current devices (RCDs, RCCBs or GFCIs) wh… WebCurrent ELCB (RCCB or RCD) Current ELCB or commonly known as RCD (Residual Current Device) or RCCB (Residual Current Circuit Breaker) is another type of ELCB …
