[QUOTE="Doc Hudson, post: 449286, member: 1607"] Phrases such as 'something has worked for 8 years' and the guy 'just trying to get the system running' suggest an acceptance of cowboy attitudes in my opinion. I would say there are two possible causes of your situation. 1) someone who hasn't got a clue what they were doing has wired it up or 2) someone who knew full well they were doing a half baked bodge job wired it up. Either way I would be wanting a comprehensive inspection of every circuit on the whole installation done, to check there are no more nasties lurking. This should have been done when the CU was changed with an installation certificate issued for the work. I could wire a socket outlet with no earth connected and live and neutral reversed and leave it with a customer thinking it apparently working OK for years without maintenance. But it would still be a bodge job leaving someone at risk of shock. Borrowed neutral, (or more strictly correct "two fuses/MCB's supplying power to the same section of cable"), is a very hazardous arrangement leaving risk of electric shock if only one fuse is isolated during any circuit alteration work.
