Evening all,
Got a strange one that I could
Do with a little advice.
I have extended a radial circuit for an extra socket. R1r2 0.41 IR 84.5mohm and rcd trips in time.
When doing zs I got a reading of 6.83 when I was expecting about 0.63 ish when ze was 0.21 on tns supply .
Started to investigate disconnected that circuit from board and found that on the disconnected CPc I was getting continuity if I tested between that and earth bar. Took all the earths out of the Earth bar but the continuity disappeared except for testing between incoming Earth and the original one that was disconnected from the first circuit. I then tested zs on cooker circuit to see if that gave a proper reading but got 6.91 and then after testing the other circuits got similar readings ! A new split load board was fitted a yr ago and got the certs and obviously no issue.
If anyone has got any suggestions I would be very grateful.
