I bought a project house last year, and unfortunately it's turned out that one of the previous owners was a keen amateur electrician. Sadly his enthusiasm wasn't matched by competence or any sense of safety, and while replacing a ceiling I've discovered a loose live wire.

Obviously I'm going to get a professional in to deal with this, but in the meantime for peace of mind I'd like to make it a bit more safe.

Is putting the wires in a terminal block the best approach, and if so does it matter if the amp rating on that terminal block is higher than that of the wire that's leading into it?

  • What do you mean by "terminal block"? – ThreePhaseEel Jul 25 '16 at 11:45

    Something like this screwfix.com/p/chocbox/54936 – Dave Jul 25 '16 at 11:46

    The UK uses terminal blocks where the US uses wire nuts... I'd say that either, or a wrapping of electrical tape, would be a perfectly reasonable safety barrier. – keshlam Jul 25 '16 at 12:59
  • I agree @Keshlam. is it also possible the wire is not hot just a spare or abandoned wire? + – Ed Beal Jul 25 '16 at 13:06

    Certainly possible (though the OP said "live")... but even if disconnected it should be covered anyway in case someone reconnects it someday. – keshlam Jul 25 '16 at 13:09

Yes, as a short-term solution, terminating the wire in a listed box is a good idea.

As a general statement, using something with a higher amp rating than necessary is fine.

If you could temporarily cut the power to the circuit, it would be even better, but I can imagine that other things are running...

  • Thanks - other things are running on the circuit so will terminate it until I've got a sparky in. – Dave Jul 25 '16 at 13:31
