@Vortigern has made a very valid point
nowhere in the original post did it say that the main isolator was still energised.
both myself and others have in our own minds assumed that it is energised because the fault described would in most circumstances require the power to be on for it to manifest itself.
@Sonia Norman
if indeed you are testing Ze with the main isolator switched on, I hope you have learnt something from the posts.
if in fact the main isolator was off then there is something unusual going on there, possibly to do with a current flow between N and earth via the rcbo fly lead .
@ everyone else, remember that we are all human and don’t get everything right all the time.
I am sure if we look back at our own mistakes and failures, the odd one will make us cringe.
I for one can look back at a couple of events that didn’t go horribly wrong, more due to good fortune than perfect methodical working practices.
