This earthing connection elcb circuit diagram allow the ELCB fulfill its purpose of being in the electrical circuit. When diagrxm earth leakage occurs in the equipment, there may be part of phase current passes to the earth, through the leakage path instead of returning via mental wire. Interestingly the main earth connection itself becomes the negative of the circuit instead of the neutral line.

Working Principle Of Earth Leakage Circuit Breaker(ELCB) And Its Advantage and Disadvantages

A wire wound coil is the secondary winding. In the tropics, this elcb circuit diagram occur, for example if a clothes drier has not been used for a year or a large water boiler used for coffee, etc. This will induce a current in the secondary winding which is used to operate the tripping mechanism.

I will cover other topics on the electrical panel in future posts. Diagram 10 elcb circuit diagram Test resistor symbol.
