hi guys,
Hoping for a little advice.
Been working on a property this week and have been having trouble getting zs readings as it trips the rcd on a 17th edition cu.
Property is pme. I've tried testing idividual circuits one by one and completely disconnecting all the others but it still trips. It doesn't seem to matter what circuit is tested it trips on every one.
I've checked absolutely everything and all tests leading up are fine. Zs tests however trip rcd.
I've done a ramp test on rcd to check that and it's fine.
I've got a feeling it's a Dno issue but they have now confirmed there are no faults on the line. Anyone had similar issues.
Thanks in advance
