Earth leakage refers to the flow of electrical current from a live conductor to the earth (ground) through an unintended path. Unintentional earth leakage tends to occur in poor installations where there could be a breakdown in the conductor insulation or moisture ingress, amongst many other causes It consists of either a current sensing mechanism, or a voltage sensing mechanism.

The installation should be designed to prevent unwanted operation of earth leakage protective devices due to the cumulative effects of leakage currents
It is particularly important to maintain continuity of circuit protective conductors for circuits with protective conductor currents.
Types, working, and application of earth leakage circuit breaker elcb or earth leakage circuit breaker is a protection device that protects against earth leakage Initially, the earth leakage circuit breaker were voltage detection devices, now they are switched to current sensing devices. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected Elcbs help detect current leaks.
Earth leakage is an unintended state where electrical current is leaking from an electrical appliance or circuit to earth (ground) Earth leakage circuit breakers are used to protect people and equipment from electrical shocks and against fire risks due to current leakage. Earth leakage current flows through the ground conductor to the earth If there no grounding or earthing system is available or improper grounding then the earth leakage current will try to flow through any other conductive path i.e., the human body.
