We have a 62.5 KVA DG with Leyland engine and kirloskar
slipring alternator. We have earthed the neutral, and another
earthing for the dg body. is it necessary to isolate the dg
foundation with rubber pads?

I've descovered that when the earth wire in a domestic
electrical installation is not connected back to the board
(ground) a voltage of between 9-24v is is found to be
present in the earth wire.
When connected at the board there is no voltage - is this
normal and why does it happen?

Sir,
My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs.
Sir, My question now when my mind strikes with 2 options
1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or
2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2
Please suggest me sir
