The metal body of the load is associated with the fault terminal of the earth leakage circuit breaker elcb the earth terminal is associated with the ground. An elcb is a specialised type of latching relay that has a building s incoming mains power connected through its switching contacts so that the elcb disconnects the power when earth leakage is detected. The current elcb or rccb consists of a three winding transformer which has two primary windings and one secondary winding. Earth leakage circuit breaker elcb is a molded case circuit breaker used in a low voltage ac circuit to provide electrical shock protection and prevent fires from leakage current.
