how come when I cut through my wiring going to my 13a sockets all the
sockets are still live? Because they are on a ring main. Should you be messing with mains if you lack this basic knowledge? MIke |

Are you serious, or this a wind-up? What did you expect? I expected the ones furthest away from where the lecy comes in to the house to go off. As someone else said, in the UK, sockets are generally wired in a ring - and have a pair of cables supplying them so to isolate the socket you need to disconnect both cables. Have a look at the wiki for starters : http://wiki.diyfaq.org.uk/index.php?title=Ring_circuit. It's important as was suggested, that you understand the basics of this before working on the system. and understand other arrangements of socket wiring you might come across. Why were you cutting the cable? What are you wanting to achieve? If you are cutting the cable to remove a socket you need to remake the ring. -- Chris French |

It allows you to create a 7.2kW circuit using smaller an lighter cable than would otherwise be required. Makes it cheaper and easier to wire. It also performs better under a number of fault conditions, and gives less voltage drop effects from high loads. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Yes, but normal GPOs aren't done like that, and if they are that wastes a hell of a lot of copper and produces one hell of a mess of cables back at the breaker box. |
