Answer Posted / t.c.raghavendran prabhu (lnt)
There are three major Factors that influences good earthing:
1) Earthing is mainly done to arrest the flow of jumping
electrons from the body to the ground because the ground
potential is zero.
2) Mainly body earthing of the equipment has to be done to
avoid the damage and losses of machine & humans.
3) Good earthing resistance is 1-2 ohms.ELCB ie,Earth
Leakage Circuit Breaker has to be placed in the Panel
boards for the safety purposes.
