    Old colours mixed with new colours

    Wouldn't normally note this as an observation on a report but feel I need to. The way the building has been wired is all circuits on L1 have been wired in old red, L2 old Yellow, L3 old blue, however as stuff has been added it's now got new colours. The property is currently empty awaiting new...

    Rewiring old plug - red, blue and black

    Hi, I'm trying to rewire an old plug. I've rewired a few in my time, but all have been with the post-2006 wire colours. I have this old welder, not really sure how old it is (I got it from a friend who got it from the dad of one of the guys he works with) but safe to say it is definitely...

    Anyone want to help me clear out old cable?

    Getting desperate to clear my small garage, and I have a bit of old red/black T&E. I used a few bits to add a socket or two in my flat and a couple of neighbours, as the development is all wired in old colours. I am well aware that there are cowboys out there who buy this online, at quite...

    Old sockets having a party

    I was off duty, but this was a nice collection all in the same place: The 5 amp and 15 amp are obvious. The 4 pin one? 3 phase? It has Red B and Y scratched on it. I seem to remember the name Rayrolle and BS196 but it doesn't seem the same? Thanks!

    NICEIC Certification Scheme SPD on old consumer unit?

    Under amendment 2 of the BS7671, there is now a requirement to fit an SPD as standard. I am due to install a new outdoor socket circuit on an old consumer unit which doesn't have an SPD. Is it ok to do this installation without the SPD?

    Will this old switch have asbestos in it?

    My customer has just moved in and wants to make sure the electrics in the garage are safe. I have only carried out a pre-works visit so far and noticed this old MEM switch. I believe it to be the isolation switch for all the garage electrics. Will it have a fuse inside it? Also, is this likely...

    Re-skilling as a old guy!

    Hi All, Not sure if this is the best place to post but here goes! I'm over 50 and not working at the moment (semi retired) but I'd like to get back into some hands on work, ideally self employed in the electrical trade. I did an apprenticeship back in the late 80's in Electronic Engineering...

    Any thoughts on this old thing?

    Quite old main switch RCD, it occasionally trips (every day or two), then won't turn on until all breakers are off. Ramp test at time of testing was 25ma, earth leakage meter said 5ma (so consistent). Is the RCD likely to simply be old?! Are they tetchy switching on under load? Haven't got into...

    Exposing old mains cables, Is this safe???

    Hello. I'll apologize to start with as due to my lack of knowledge on the matter I'm likely to waffle a bit and call everything by the wrong name but hopefully you'll get my point... I am having some renovations done at home and need to have the electrical meter relocated slightly. We have...

    Old service head, refer to DNO or not?

    I've got a job in a tucked away property that has an old Lucy Oxford service head. It's been a while since I've come across one. Am I remembering right that the DNO's are generally interested at looking at and changing these? Thanks.

    Is 29/30 years age too late to start an sparky apprenticeship?

    Hi all. Apologies if this is a dumb question but I am wondering if anyone can confirm any success stories of someone who got into the trade at late 20’s/early 30’s? Long story short, I’ve recently come out of the forces and after a big chat with mates in different trades, they’ve suggested I...

    EICR question, OLD AC RCD- code 3 or no code?

    With regards to Regulation 531.3. 3 of BS 7671:2018+A2:2022 Older AC type RCD's are prone to being blinded by dc leakage from other items plugged in to the property. In other words this RCD may fail to operate when other electronic items are plugged in which leak DC in to the mains. Regulation...
