    House has a lean to with a metal clad box and plastic double switched socket adjacent to a waste water drain.

    A lean to with a metal clad box and a plastic double switched socket fitted to it adjacent to a water drain for a washing machine. Obviously I am not happy with it so thought I would fit a BG weatherproof IP66 as a direct replacement; thinking I had to remove the flex I pulled some 2.5mm T&E...

    Metal saddles for communal areas

    hi guys So I'm tasked with replacing plastic saddles in communal areas. App D in the OSG says saddles can have a max spacing of 1.5m apart. I know from past experiences that any conduit passing over must have a metal saddle in place. So was wondering will it be OK to replace the plastic...

    UK Changing plastic light switches to metal

    Hello! Complete novice here. I'm changing a plastic light switch to a metal one. There's a metal back box. I intend to run the earth cable from the wall into the back of the light switch faceplate. Then run another earth cable from the faceplate to the back box. Is it as simple as screwing in...

    UK Twin and Earth in metal trunking

    Hi guys, I had to carry out some alterations to a domestic installation the other day and was pleasantly surprised when having to run a new circuit how neat the CU was. It had 75mm metal trunking installed to the CU with bass bushes installed. A lot of effort had gone in to it to keep it neat...

    Dado metal trunking

    Looking to put in some dado style trunking for a few power circuits and some Ethernet sockets, ideally metal type from a fire/EMC point of view. I had though of using the Marshall-Tufflex "System 130" (or maybe the bigger 170) steel system but wondered if the folks on here have any better...

    Earth bonding metal balcony

    Last year I had a large cast-iron balcony constructed with steps down into my garden. The balcony is bolted into the walls and also into the pavement where it meets the garden.

    Bonding Metal Railing

    Hi, I'm taking swa out of the shed and fitting it along a metal fence with metal fixing band. Swa goes into a wiska box then flex from the box to a light that's bolted to the metal fence. Circuit is protected by rcd. Does the fence need to be bonded at all? I'm guessing it's an extraneous...

I assume the builders left them like this in the event people swapped to metal like...

    "sorry love, you need a new metal cu, it'll make everything so much safer"

    I can't get my boards as artistic as some of the YouTube sparks but came across this absolute shambles today... I know there's cowboys in all walks of life but do any other trades suffer so much with unskilled people charging money to do skilled work? (and getting away with it)

    Hi, had a rewire done, sparky didn't replace some of the metal back boxes, just run new cables into them, I don't have a problem, taking them out would have caused the plasterboard to get damaged, but mrs thinks they should have been done. Seems pointless, they are metal, new rubber grommet...
