An ELCB – earth leakage circuit breaker is an electrical device mounted on the fuseboard which detects when the electric current is not balanced between the outgoing live conductor and the returning neutral conductor. Such an imbalance may indicate current leakage through a person, when such imbalance is detected the circuit is automatically disconnected within 30 milliseconds. An ELCB thus helps prevent electric shock and should be fitted to all fuseboards. There is also a test button on all ELCB’s – when this button is pressed the ELCB should trip thus disconnecting the supply.
