    Trunking- to use PVC or Steel.

    Normally I would say PVC for a small office in a house. However, they are in the middle of deciding if the building will become a six-bedroom hostel for people with issues (so there is a possibility the office might get damaged), or if it will be converted into a dental surgery. The risk...

    PVC cables buried direct

    Hi All I was having a discussion with my colleague regarding burying a swa directly along with a pvc earth cable. As the earth is not an armoured does this need to be ducted for mechanical protection and if so is there a regulation in the BS 7681 for it?

    Crumbly PVC cable (red only)

    Today on an EICR I came across some old (1960's, I think) PVC lighting cable - twin red/black, no earth - where the red was crumbly. It behaved like old perishing rubber, any bending and it cracks - but it is defintely plastic of some sort. The black was perfectly OK, as was the sheath. Curious...

    Why are metal electrical boxes so small (compared to PVC?)

    Hello all. First post. DIYer. Know enough to be dangerous (LOL). It seems "standard" blue PVC boxes here in the US are 2.25" wide and depth can go up to 3" deep. I've got an old house (built in 1955) with old BX armor shielded cable, and the old boxes are extremely difficult to put a dimmer...

    Tool for 45 and 90 Degree Cuts on PVC Trunking

    I have bought a Mini Mitre Block for some Trunking as the cutters I have are better for Mini Trunking. I’m just looking for something that will allow me to mark the angle before cutting it. I was thinking either a Tri-Square or Trend ANGLEFIX. I then also need some advice on a file to smooth the...

    XLPE vs PVC

    Long story short I ordered the "wrong" cable.... wanted H6241Y but mistakenly bought H6241B Now, rather than faff with sending it back, I believe I can still use it but want to check with the pros. Its for a domestic lighting circuit that is currently run with live/earth loop to the switches...

    PVC Back Box w/ Multiple Knockouts

    Hi does anybody know of single / double PVC back boxes that have multiple 20mm knockouts like metal clad? Or are plain with no knockouts ? The ones with one 20mm and trunking knockouts don't really work as when cutting the 20mm hole the trunking entry normally splits even when bracing it.

    Hi, I am wondering if any sparks out there know of a brand of 32mm deep PVC surface boxes with multiple knockouts for MT2 & MT3 ( 25mm x 16mm & 38mm x 16mm) mini trunking. Marshall Tufflex MSSB35 & 36 WH were perfect but are now discontinued, and their replacements MSSB91 & 92WH only have a...

    Difference in scrap price between pvc insulated twin & stripped cable.

    I’ve got a hell of a lot of scrap cable in my garage. I know it would take a long time but is it financially beneficial to strip the cable or does it not make much difference?
