I've just started learning about testing and I know how to do the majority of the tests but was just wondering how you would do your Ze etc when theres no incoming earth on a TP & N board?
Wondering if the OP means on a TT system as opposed to a TN?was just wondering how you would do your Ze etc when theres no incoming earth on a TP & N board?
or would an earth also be run in?
I just got the impression that a TP & N board was three phase & neutral which would have a swa with 4-cores? or would an earth also be run in?
IMO you are getting ahead of yourself.I've just started learning about testing
