Hi everyone,
I have a particular job visited this morning, that on all circuits, at each point, i got a reading off around 25ohms for a earth fault loop impedance test(zs).
I then thought to do the same at the DB for those circuits. Again, same reading was obtained.
I then turned off the whole installation, to obtain a Ze with the incoming earth disconnected. Same value obtained.
Can anyone shed any light to what may be going on here, I suspect an issue on the DNO side of things?
Thanks in advance.
