what is the difference between earthing and grounding?
Answer Posted / devsingh boda
Grounding: Connecting the live part (part which carries current under normal conditions) to the ground (earth).It is done for protection of devices under fault conditions.
EX: Transformer neutral
Earthing: Connecting the dead part (part which does not carry current under normal operating conditions) to the ground. It is done for protection of operators who operates the device.
