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'
