According to Indian Std. DG Set Should have four Earthing
Pits Each Should have Separate Copper Plate Accoring to Std.
-Run two properly sized Copper or GI Earthing Conductors
from the Neutral Bushing/Terminal of the DG Set's
Alternator and connect one each to the two neutral earth
pits. Similarly, the alternator will have two earthing
terminal on its body (at diagonally opposite ends); Run two
properly sized Copper or GI Earthing Conductors from these
body earthing terminals of the DG Set's Alternator and
connect one each to the two body earth pits. But, you MUST
inter-connect all these four (two neutral and the two body)
earth pits by properly sized Copper or GI Earthing
Conductor.
