Not that i'm allowed to touch my home electrics anymore, (Part P, grr) but say I had a mystery wire dangling near my fusebox, which disappears into the 1st floor landing void. How could I identify this wire without energising it (as i'm not at all sure what is connected to the other end) I have a sneaky feeling it goes to the loft, but have no way of so determining.
The other wires all go to a CU with MCB's, so isolation of all the other wiring is not a problem.
How do the experts identify individual wires once they've gone through floor voids etc .. ?
I'm sure there's a simple explanation staring me in the face here !!
Cheers
Paul.
