Q.10 What is ELCB?
Answer
An Earth Leakage Circuit Breaker (ELCB) is a critical specialized safety instrument engineered strictly to detect hazardous stray leakage currents to earth and proactively disconnect the electrical supply.
An Earth Leakage Circuit Breaker (ELCB) is an extremely vital electrical safety device systematically installed in domestic and industrial environments strictly to prevent severe electrical shocks and potentially fatal electrocution hazards.
It continuously and rigorously monitors the precise electrical current flowing entirely through the earth wire or detects minute voltage imbalances. If damaged insulation or a physical fault causes even a microscopic stray leakage current to flow explicitly from a live phase to the metallic casing (and thus to earth), the ELCB instantaneously detects this fault and automatically trips, entirely disconnecting the mains power supply.
