Master44,
I've lost count of the times, when I have turned up to a job, to find that all of the wiring is botched, and no-one wants to take the blame, in this situation, I would instantly call an Electrical Inspector, they have amazing powers of finding answers over here in NZ!. [Linked Image]
Most of our Inspectors, are still employed by the PoCo, and the threat of refusal of supply, often works wonders.
A few times, I have come across a faulty installation after all of the walls have been lined and covered with expensive wall-paper, too, this doesn't tend to go down too well, when you try tell the home-owners that you may need to cut some parts of the walls,
to find the wires!. [Linked Image]
