Hi,
I have a garage and have a consumer unit in it. It is fed by a 6mm armoured cable with live, neutral and earth. Each circuit has a a trip switch and the whole thing is protected by a rcbo.
My problem is that I have a circuit which has neutral and earth live!! The problem doen't stop there. If I connect the + from a seperate cable to the + from the supply and have all the wires seperated then they all become live EVEN though none of them are connected, touching etc. It doesn't matter what cable I use so there is no issue here about a damaged cable. All the wires are insulated with in the insulated cable including the earth wire. The rcb etc does not trip. Since this is a garage and there is a lack of metal pipes do I need an earth spike outside, and is this an earthing issue or have I defied the laws of physics!! The garage is 50m from the housewhere the supply is taken from.
Thank you in advance for your help
