wiring in a double socket
Posted: Wed Jan 28, 2009 3:27 pm
:?: I am renovating the sitting room and want to move a wire to put it under the floor. The problem is that when I opened up the double socket the results I get with a circuit checker are not what I expected and wonder if I have a problem. I think it is a ring main, there are two red wires to the positive,two black wires to the negative, and I think one (it could be two wires to earth. All as expected. But when I check the current I find I have 240V between pos and neg ( normal) BUT 240V between positive(red wires) and earth. Is there a problem? Everything seems to work OK. I know how to add a spur which I need but am worried about the earth aparently being alive.
