    Current in Live and Neutral wires in FCU

    Current in Live and Neutral wires in FCU 1st Oct 16 at 10:45 PM
    I am attempting to create a Fused spur from a power socket for some wall lights.

    I have managed to fit and wire the Fused Connection Unit and spur it off the power socket. However, the lights themselves don't work and when I test with a voltage tester, both the live (brown) and neutral (blue) wires in the FCU are showing as having a current!

    I've checked the connections which seem to be fine, so I'm struggling to understand what I've done wrong. The wires from the power socket are all connected into the connections marketed IN and the wires to the lights are in the ones marked LOAD.

    What am I doing wrong?

    Pictures would really help up confirm you are doing it correctly.

    There is a fuse in the FCU?

    I'll have a quid you've connects some the wrong place on the wall light.

    I consider myself competent at electrics and recently had a new wall light that had hidden connectors, but brackets that absolutely looked like connectors.

    Doing this effectively loops the live and neutral which would explain the behaviour you're seeing, and why the lights do not work.

    Recheck the connections at the wall light and then if you're certain they're correct, I would agree that you need to call someone.

    I've managed to get it working!!!

    The flex from the socket to the FCU had the neutral cable snapped. It was difficult to see initially as I had buried the cables into the walls and hence I why I was looking for a logical answer without having to chase out the walls again.

    There is nothing self-righteous about pointing out that you are required to conduct an initial verification of the wiring to prove that it is safe to put into service.

    Did you inspect the wiring and carry out dead testing before energising, and live testing after energising? Of course you didn't.

    How can you state with any certainty that it is safe to be put into service? Of course you can't.

    I'm with Risteard, if you were getting two different voltages at opposite ends of the same conductor it should have been obvious immediately that the cable was broken. Have you asked yourself what you did to the cable to fracture it, or whether there are any other fractures in your work waiting to cause a fire?
