    UK Plastic to metal consumer unit

    Hi Looking for some advice please. I started renovating my house in 2015 and as part of this I ripped out all the wiring and got my electrician to rewire it including a new plastic consumer unit. There is still some electrical work to do so none of it had been signed off yet. As the plastic...

Although I will use 3 core cable I was surprised to see that the existing cable used nis 2 core which goes into a plastic socket and the main surround...

    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?

Most computer cables are sleeved paracord, mesh or silicon but I want to make more rigid cables that are able to bend somewhat easily.

    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...

    SWA metal exposed on main

    I’m having a new wall constructed. Whilst digging the foundations the workers came across the incoming main. Note that the steel armour is entirely exposed. U.K. power came to confirm it was their cable but didn’t mention anything relating to the cables condition. Surely this is a ticking time...

    UK Metal clad cable entry

    Hi all, level 3 qualified sparky here, just getting back into it after some time out. So, what is considered best practice these days when installing a metal clad consumer unit. Are all these Fancy Dan cable glands actually required or are they just another money spinner. I've found if you...

    "Safety Electrical Connection" metal labels

    Does anyone know a source of just the metal labels that are attached at earth clamps? Every time I need to replace a missing label, I'm taking a label from a new clamp, and throwing the clamp away, which seems a bit wasteful. I'd love to buy a bag/box of 50 or 100 of the metal labels.

    Metal web / posi joists

    I don’t work on many new builds and the builders I usually work for don’t use them, so this is the first time I’ve come across posi joists at work. I suspect I know the answer as to what usually happens here when running cables - ie they’re just lashed in ‘bow and arrow’ style, but does anyone...
