    change of mcb to rcd

    The cable has been there since we bought the house, 13 years ago. The T&E is buried somewhere under 4" of concrete and I have no desire to dig that lot up at 73 y.o. Running a new cable overground wouldn't be an option as I would still have to dig up across either my drive or patio. As I am...

    1. The cable to the garage was in situ before we moved to the property 2. The run is about 30mtrs. 3. The cable is underground and appears to be basic 2.5mm 4. I realise that it doesn't meet standards but I would prefer not to have to excavate the patio to re-run the alternative higher...

    main earth bonding to water and gas

    the connection, in my case, cannot be within 600mm of entering the building AND accesible. It would need to be one or the other. Is the key word in the regulations 'should' rather than 'must'?

    wall tiling on plywood

    I am putting in a back to the walll toilet and building the cabinet rather than buying one. I want to tile it, when finished, to match the walls. The salesman in the tile shop told me that tiles do not stick well to plywood. As plywood is my preferred material to build the cabinet this may...

    bathroom shaver socket installation

    PrenitceboyofDerry Bahtroom isn't big enough to move it to a distance of 3m. It would be about 2.2m. But it would be a switched fused spur, NOT a socket and firmly outside of zone 2. I've tried asking some 'sparks' and get differing views re: fused spur. I've also read reg. 701.512.3 (which...
