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?
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
