A sad tale here, a friend of mind died recently and I went to see his workshop with one of his daughters to give her a hand. He was quite an interesting guy and generally very practical, but sadly not terribly good at electrical work, shall we say. Some of the originals stuff there was installed to a good standard, but in at least one of the boxes L2 was white wire, making it older than myself!
I was not there for electrics, just to lend a hand cleaning/moving stuff, so the only thing I could actually deal with there & then was the extension lead's plug with tools I usually have in my car boot.
The SWA from the switch (or switched-fuse) is really a spectacular example, it is connected but only by a handful of strands. I really would like to know why it ended up like that as I presume it was properly glanded in the past. The main set of DB used to feed multiple units in an industrial block but the left box of fuses now has just a single 40A circuit that is not on the unit's own billing meter, but nobody I asked has any idea of who/why it remains from this separated unit now.
Of course it needs major renovation, realistically a rewire and all of the stuff replaced, but I might have to do something (like a new SWA gland!) until the estate is sorted out and the siblings who now own it can agree on getting it sorted out professionally.
