Elcb Switch Off When Current In The Earth Wire Is Greater Than. If any current leaks from any electrical installation there must be any insulation failure in the electrical circuit it must be properly detected and prevented otherwise there may be a high chance of electrical shock if anyone touches the installation an earth leakage circuit breaker does it efficiently. Elcb is working based on earth leakage current.
An elcb is a specific type of latching relay that has a structure s incoming mains power associated through its switching contacts so that the circuit breaker detaches the power in an unsafe condition. The circuit will immediately switch off the mains on detecting a missing earth connection or a current leakage through the appliance body. The elcb detects fault currents from live to the earth ground wire within the installation it protects.

There are many cases in which there is a current flow in the earth wire but the situation is not hazardous in such cases but it gives false trip e g.
