Answer Posted / mahamuni raja
to determine the no.of earthing pits required is depends
uponn the area required to dissipate the fault courrent to
the area of pipe electrode.
To protect 35M building , 1no. of lightning arrestor is
sufficient however better to provide two nos.of down
conductors hence to protect the building if any one
conductor fails.
