    Hi experts, Several of the handles on my double glazed PVC windows have become loose. At least two of the handles have become so loose they feel as though they may come right off. For the life of me I can find no handle screws to tighten, and there are no cover plates that I can see. I...

    Cause of electric shower failure

    Hi Experts, My Mira sport max 10.8kw shower gave up the ghost last week. When I turned it on for the last time there was a loud ‘pop’ or ‘bang’ then shower went dead (panel lights went off). What worries me is that the RCD that supplies the shower (Wylex, 80A, 30mA) didn’t trip. I have since...

    TN-S or TN-C-S ? (with photo)

    Cable size on supply side of FCU

    Hi – I want to spur off my ring main (4mm T&E, protected by 32A MCB) to provide power for an outside security light. I’ll tap into the ring with a 30A junction box, then feed the light via a switched, 3A FCU. I’ll then run a 1.5 mm T&E from the FCU to the light. Total length of spur is about 4...

    Providing earth for small transformer

    Hi - I bought a small transformer when I moved to the UK so that I could still run some of my small 110/115V electrical appliances. The transformer I have is described here (Model 170B): http://www.hammondmfg.com/pdf/5c0073.pdf The diagram seems clear enough as to how to wire it up to go...

    Burglar alarm problem

    Hi, I have an Intellisense 800L burglar alarm system, which was installed in 2000. When I shut off the mains lighting circuit the alarm is activated and the control panel (touch pad) goes dead (i.e. no lights). This has just started happening recently. I have a feeling the battery may be...
