I've a few questions about the supply characteristics of a job I went out to last week, if anyone fancies commenting.
1. Does anybody know why a supply with a PME notice on it, appears to be fixed up as a TNS system?
and
2. There's two incomers. Will one be going to feed next door?
3. The tails are 16mm but the cut out fuse carrier says 100A. I'll try to check with the supply company tomorrow what the actual fuse rating is but if it is indeed 100A are the DNO obliged to come out and upgrade the tails?
For those interested, I was called out to a fault on the socket ring when the RCD wouldn't reset. I traced it back to this:
It was hidden behind a built in dish washer, with no way of isolating the washer in an emergency. There was no need for the socket at all as the washer's lead easily reached the double socket above the work surface, so I traced the spur back to this hidden JB (I'd no choice but to cut through kitchen unit to get to it)...
...which also had another spur running off it for the drier in the basement and got rid of the offending socket all together.
4. What certification would you record this work on? A MWC? Would you have two lots of test results - one before you rectified the fault and one after?
Cheers,
Ants
