Tracing hidden electrical main wiring

[Moscow Mule]

And i'm not laughin at the wife joke. It's the crap reviews that device gets. Have you actually bought one.

It's not a stud detector, it's a wall detector. I can detect walls on my own, even with my eyes shut, so this isn't a lot of use to me.

Coffee keyboard interface moment...

There's no ring main. More like a star system. Continental you see. I checked the fuse box, but these sockets do not seem to connected. If I can trace the wires I can connect them either to the fuse box, or to an existing circuit.

I have to say that IMHO, if you don't know enough DIY to be able to trace the cables, you don't know enough to re connect them.

The rules about the way that leccy cables are connected are there for a reason.

I have done small scale electrical wiring before, so know what to do connect the circuits. Won't be suing anyone on this board if the unqualified advice leads to me receiving a nasty

I can easily trace the wires by ripping off the plaster etc, but want a more subtle method. The metal detecting method is the one I will try first.

Thanks for all replies

I have one of these and it works perfectly. You have to know how to use it though. Turn it on using the dial and turn up the dial until it beeps, then turn down the dial until the beeping stops and then go looking for pipework/wires/etc. If you turn the dial up to full it will constantly beep and if you only just turn it on it will never beep.

I would suggest the users writing the reviews don't know how to use one. I haven't gone through any pipework/wires since I got mine (although you have to realistically expect it to have an error margin. For example if you have a double thickness wall with pipes behind the first layer of bricks it probably wont sense it.).

Ardeso speaketh the truth. I have one as well, and setting it up for use has to be done properly. Never failed me.

I don't know how good it would be in detecting a dead copper cable though... I shall experiment a bit if I can find the flipping thing & let the congregation know...

It's a metal detector. It detects pipework and studwork (or the nails into) as well.

Special detectors! Pah, I have a cheap 1970s transistor radio that works fine at detecting mains wires. Not dead ones probably, for that I think you need one of those dogs like they used in Jersey.

If you are sure that the sockets are dead then you could use a Cable Tracer

Used for tracing network/phone cables (You would however have to modify a plug so you can connect the tone module)

Yes, this type of thing could be useful if the metal detector does not work. Will get the MD first as that will be useful for other jobs.

Disconnect cable from wallsocket.
Remove socket.
Get a grip of the end of the cable with a good pair of grips.
Give a firm yank and keep pulling.

That should trace the cable for you!

I would not recomend using old unknown cable. Replace it.
