An RCCB or Earth Leakage Circuit Breaker (ELCB), commonly known as a circuit breaker, is a safety device that cuts off electricity supply upon detecting electricity leakage in your home. It protects you and your family from electrical shocks or injury. Electrical current leakages can be caused by factors such as ageing or exposed wires, faulty electrical appliances, and damaged insulation.

The RCCB or ELCB is usually located in the distribution board (also known as “DB box”) or circuit breaker box in your home. It can be identified as a switch with a ‘Test’ button on it.
