What would we do for work without DIY, eh? Got called out this afternoon to a, "my bathroom light's just stopped working," scenario. It was old-ish single core wiring with a neutral loop, but just a live feed from the switch.
Lamp okay, connections old but sound. No live to switch, hmm... "Have you disturbed any other fittings?" I asked, not unreasonably. "No, not a thing." I couldn't help but notice that there was a dustsheet down in the hall, so I followed the sound of heavy pasting to find a decorator in the adjacent bedroom. Sure enough both the ceiling rose and the switch were dangling. Let's have a look...
Live running to L1, switching to Com... "What's this other wire in L2 then?"
"Oh yeah," says the decorator, "when I took the switch off there was a wire loose, so i put it back." Naturally, bless him, he'd assumed that as there were three conductors and three terminals...
Dingbat smiles, sorts it out, takes the money and disappears into the night. Heh, heh, heh.
