Hey!
Am renovating a house.... involved stripping out the plumbing and start from scratch.
Was cutting through a hot water pipe and rested my hand on the cold - got a buzz. Popped the multimeter on and discover 90v.
Have yet to identify the circuits in the fuse box but taking 1 fuse out drops the voltage to 52, a 2nd to nothing.
Would the few pipes pick up induced current - so far, I've seen cable running through the same notches as pipes, under the floor.
Popping 1 of those socket testers in a few sockets and all, so far, suggest no earth in place. Does that explain why, when pressing the yellow trip tester... it doesn't trip? The earth isn't earthing?
There's the real old unsheathed earth running through plaster down to the watermain. I see [not poked around too much yet ] a thin sheathed earth [6mm?] from the breaker to the fusebox and down through the wall where it's cut from an earthing stake, and some thicker sheathed earth [10mm?] also running from the fusebox downunder the floor - ever hopeful it's doing something but I guess not......
I will have to get a sparky in to check out the whole lot, but intrigued by the source of the 90v really!
Also intrigued by what could possibly have been running on the 2nd [10mm?] tails out of the trip. Regular tails from meter to trip to fusebox but these thinner ones are cut and bared live, neutral and unsheathed earth of about 8" length just hanging there.... must have connected to something!
Mind you.... this is the place where the 8.5kw leccy shower was wired into the side of a broken wall socket in the bathroom.... used 2 lengths of cable and a bare terminal block just under the lip of the tray....... So nothing is going to surprise me... probably cut the earth as the trip kept tripping!! Hah!
