    2 prong appliances with metal casing, are they safe to use ?

    I recently learned the importance of electrical grounding and checked all appliances in my home. Toaster, Microwave oven have 3 prong power cord, so their metal casing would not cause any shock if the device has worn out connection inside. Some others like fans on the floor have only 2 prong and...

    Screws on Metal Backbox won’t tighten.

    I’ve been changing some sockets and the last one won’t tighten. They have used 75mm screws. The screw just slides into the lug. I’ve got a CK 3.5mm tap and tried that. Still no luck. Has anyone any tips or tricks? Or any screws that I could buy to make it tighter in the lug?

    Metal CU in a commercial setting

    Hi, Just wondering what people interpretations of the regs are regarding metal CU's in a commercial setting. I've seen some people code them C3 on an EICR and others say that the Metal CU's are just for domestic settings. I've read the regs and I think they could be read either way. Anyone any...

    EICR Code for metal light switches with earth to backbox

    Posting this more as a discussion than seeking advice, as I've already fixed the issue. EICR on a house which at some point had been 'done up' with metal face plates for all the switches. When checked with a wander lead R2 was within spec on the ones I tested, but when taking a random one off...

    Metal CU. Why?

    Metal CU. Am curious to know why the UK regs demanded a metal CU. Would it not have been helpful to first investigate what was causing overheating the CU?

    Low profile metal trunking?

    Currently on a job which is a garage extension. I have lots of cabling dropping down to multi gang switches, sockets etc and a small DB. The ceiling is however a fire barrier. Does anyone make a low profile steel trunking that will butt neatly to a metal clad socket or small DB?

    AM2S Metal Conduit Clarification

    Hey Just dropping this question to anyone that's passed the AM2S. Could i get some clarification on what the AM2S specification require's for the metal conduit. I've heard contradicting requirements. XS training online videos states that the metal conduit has a 3x 90' bends and a 45' offset...

    Went to a job today and noticed a length of metal conduit going across a pathway. The metal conduit is not earthed.

    I just wondered what people’s thoughts were as to weather it should be earthed being an extraneous conductive part? It’s fixed to the concrete floor and if there was a break down in insulation there could be a potential difference. If you do bond it could it be introducing a risk? 1598092922...
