    Ferrules - can they go over the wire sheath?

    I'm replacing a threaded lamp holder and the original wires had ferrules on the end so I'm replicating this as it seems like it ensures a more reliable grip between the contacts. Given that the entry point for the contacts will create a 90 degree bend in the wires, I think that the kink will be...

Then to top it off the joiner has fixed a stick to the concrete putting pressure on the cable. I’ve done IR &...

    Just removing the sheath on a ring main cable in a 3 terminal junction box.

    Over the years as a DIY-er I've used the old brown 30A circular junction boxes to add spurs to ring mains. I like them as they are strong, secure and visible. I've ALWAYS followed the rules on domestic electricity . Until earlier this year I've been able to check with a cousin who's a...

    SWA sheath, earthing and empty consumer unit space

    Hi all I had some house rewiring undertaken on my house and have come across a few issues since painting. First thing was damage to the rubber outer sheath of the SWA cable on the outer wall which I've rapped electrical tape around temporarily as the metal rods were visible and we had a lot of...

    Lead sheath SWA as earth

    I attend a job today and can see the Main earth is via a tag to the SWA lead. I called DNO and they informed me if the ze is within permitted Tn-s values (which it was 0.20 Ohm) then leave it in place. I requested a PME upgrade and they wasn't keen since this was in place. Looking for some...

    Swa sheath size too small

    an outbuilding is supplied by a 50mm twin SWA cable from a PME supply The assessor has told me to convert to a TT as the steel csa is too small, is there a way I can prove that surely a 50mm twin swa sheath is suitable to be a 16mm earth?

    Drilled through wire sheath, advice to make safe until after Xmas

    Hello, I drilled a hole late last night after a long day and stupidly didn't check the wall directly under the plug socket (I know). The RCD tripped and it appears to have just exposed the copper wires, just the sheath is damaged (pics attached). From a bit of googling it seems there is no...

    Section cut from outer sheath of armoured cable.

    Some of these armoured cables have a section of outer sheath cut from them the only reason I can think of as to why is to get a better bend on the cable, any thoughts?

    Bare mains cable - No sheath

    Hi all, this post is more for my own clarification, we have a council house in the UK and several years ago the cabling was essentially found to be dangerous and it was decided that they would rewire the entire house, all fittings, sockets, breaker boxes etc. They managed to achieve this in only...

    Question regarding old steel TN Earthing conductor from supply sheath

    I'm a little confused as to where the responsibility lies for the conductor described in the title. You know the type - on old TN supplies where you've got a bare multistrand conductor coming from the sheath to the M.E.T that's always of a fairly piddly CSA. My understanding is that this is the...
