[QUOTE="Nicky Tesla, post: 4520, member: 445"] Your diagram proves yourself wrong. Cos the voltage exported to cct b from the dis board earth bar is not the same voltage that is present at the fault cos the fault current has had to pass through R2a first which creates a voltage at the earth bar lower than at the fault. So it is not like a load of resistors in parallel is it, but in series like i said. Also there is a touch voltage that is mentioned which is well known to be at 50v, but you say all your ccts will have a voltage of 230v on the cpc and metalwork, so something is obviously wrong with what you say.
