    Had UKPN come out to a property recently to upgrade the main fuse from 60A to 100A but when they arrived they said that the supply cable which he confirmed is a 25sq.mm. CNE aluminium concentric cable (1-phase, burried) for the PME supply is only able to take a 80A fuse. They will have to dig...

    Long cable rods

    We might need to pull a cable through around 100m of fairly wide duct (around 10cm) and it might not have an existing draw rope. It has a 28mm water pipe and CAT-5 network cable in there, so one option might be to use the cable as a sacrificial means of pulling a rope and another cable through...

    Hi all, I have a light in the under stairs cupboard which is controlled by a switch in the hall. The under stairs cupboard is being taken out soon, meaning the light will be redundant so obviously I would like to make safe and remove it. There is no loop in/out at the light fitting...

    What cable for this outside light

    What cable would you use to connect this light through a cavity wall to a FCU the other side of the wall? I am thinking, 1.5mm² 3 Core NYY-J Cable, or 1.5mm² 3 Core Rubber Flex. The light that is being replaced has twin and earth as it has choc box connectors which won't work on the new light...

    What is this black tarry stuff on the cable?

    I have been carrying out an EICR on a property and have come across this black tarry substance on 2 of the cables. I have seen the pitch oozing out of a cut out before and I don't think it's this. Mainly because I thought that was only on the cut out fuse. It's also not green, so it's not...
