Hey folks
Doing a PIR for someone the other day. This is for a guy who did the wiring for his own extension. his story was that the electrical company sent to him by the local building control came to look at the 1st fix but wouldn't return for final test and sign off. Building control asked him to get a PIR done on his extension and that they would accept that.
He told me that he was a very experienced and succesfull engineer so electrical work was easy for him.
Anyway I agree to do a PIR on the extension. I thought it was a pretty sloppy install to be honest. Things like; connections to downlight transformers just left as exposed connector blocks and no enclosure, no earth sleeving, no identification of conductors, no grommets. Nothing major but a bit rough i thought.
I then went to do an insulation test on the new light crcuit he had installed, which he had just put into the same circcuit breaker as the existing upstair light circuit (the new circuit feeds the upstair lights in the extension). So I just disconnect the new cable that he has installed to do an IR test on it (agreed limitations are just for testing the new work). Anyway my tester wont allow me to do the the test - why? - because it was 200volts L-E & N-E. WTF! i thought. The only way to de-energise the new cable was to switch off the adjacent breaker which operated the downstairs lights.
This is as far as I go, my job there wasnt to trace and recity faults, only to report. My first thoughts though are; well this must be interconnected with the landing & hall lights, neutrals interconnected, that sort of thing. But what is weird is that when this cable is in the breaker for the upstair lights with the downstair light breaker switched on, the cable and top of the upstair breaker isnt live. Only when its removed from the breaker is the cable reading 200 volts. Weird.
Im sure my explanation is a bit difficult to follow here but any ideas? anyone?
