Hi,
I was going to post this in the DIY forum, but I can't seem to view or post anything there...
Pulling up some floorboards in my old victorian house, which previous owner had re-wired recently, I found a cable which has been cut off. When I passed my non-contact live wire detector over this cable, it gave the warning signal for presence of a live wire.
I haven't managed to trace this cable back more than a few metres, as it'll involve pulling more floorboards, but it does run alongside some of the new wiring for a few metres; could the current detected be induced by these other cables?
And how can I test to be 100% sure there is no current? I might pop out and buy a multimeter. If I strip the ends of the wires (with the power off!) and then put the multimeter across live and neutral (on the correct setting), would that tell me whether or not this wire is live? I've seen a video of someone doing that with a socket, but it sounds a bit dangerous to me...
I just want to be 100% sure this wire is safe, as I am wary of working in that area of this room in case I brush against it accidentally...
I'd really appreciate any advice here, so I can get on with things!
