Answer Posted / khaja tajuddin
whenever a live wire touches an enclosure of an equipment a
ground fault occurs, so to provide the personnel protection
the equipment enclosure is connected to grounded neutral
wire through a grounding conductor to make earth and
enclosure electrically common. At the same time the ground
fault current flows from the enclosure back to the source
to trip the protection device
