Answer / amit gathiya

As per IS 3043-1987, vide Cl. 0.7, the terms
‘earthing’ and ‘grounding’ are synonymous.
Perhaps the different nomenclature is due to the
usual conflicting usage of English language
between the Americans & the British. While the
British termed it as ‘earthing’, the Americans
termed it as ‘grounding’. IEC & IS Standards refer
as ‘earthing’, while IEEE & ANSI Standards refer
as ‘grounding’.

Answer / rks

Ground or earth in a mains (AC power) electrical wiring
system is a conductor that provides a low impedance path to
the earth to prevent hazardous voltages from appearing on
equipment (the terms "ground" (North American practice)
and "earth" (most other English-speaking countries) are
used synonymously here). Under normal conditions, a
grounding conductor does not carry current.

Neutral is a circuit conductor that carries current in
normal operation, which is connected to ground (or earth).
