diff between grounding & earthing
Answer Posted / kunal
electrical supply system is often connected to earth
ground, ground and neutral are closely related. Under
certain conditions, a conductor used to connect to a system
neutral is also used for grounding (earthing) of equipment
and structures. Current carried on a grounding conductor
can result in objectionable or dangerous voltages appearing
on equipment enclosures, so the installation of grounding
conductors and neutral conductors is carefully defined in
electrical regulations. Where a neutral conductor is used
also to connect equipment enclosures to earth, care must be
taken that the neutral conductor never rises to a high
voltage with respect to local ground
