How many earthing pits required for diesel generator set ? Why ?

Answer Posted / ankur bisen

For a single DG set, 4 earthpits will be required - 2 for
body & 2 for neutral. Suppose you have 3 DG sets then 8
earthpits will be required - 2 for body earthing of all
three DGs & 6 for neutral(2 for each DG). The two earthpits
for body shall be in grid. The two earthpits for neutral of
a DG shall also be in grid, but earthpits for neutral of
different DGs shall not be in grid.
