    Suggestions for outdoor power for 12V garden lights

    I currently have some 12v outdoor lights which have a plug with a built in transformer. I would like these to turn on and off without having to go outside so ideally would like to have them on a timer but not sure of the best way to incorporate this while keeping it looking presentable...

    That MK Rapid Fix socket thing

    First time I've seen these and I'm intrigued... Are the MK version the only type out there? Do they only come in white? Is it only sockets that are available? What about spurs? Do they have test points?

    Convenience Store Lighting Rewire

    Everyone's had 2p put in their box tonight it seems! 😂 Metal fixing band above the ceiling as containment. Again, cost cutting. Usually fit basket tray but this is £10-£15 per length as opposed to a £5 roll of hole-band!

    Convenience Store Lighting Rewire

    Wouldn't say it was customer-led. The customer was given acceptable options and decided for themselves what they could afford. I don't see an issue with that. Whats the health and safety aspect of the proposed work which concerns you?

    Sounds like H07-RNF is what I'll be needing then. Thanks for that.

    Convenience Store Lighting Rewire

    Suspended ceiling already in place. Customer wanting to save costs and not interested in paying for marshaling boxes etc. Good old fashioned in and out using wago accessories has been agreed. Definitely not my preferred method or first choice but can't see any reason why this isn't acceptable...

    Convenience Store Lighting Rewire

    Any issues with wiring lighting in 4core flex rather than 3core and earth? Approximately 50 LED panels to wire all fitting into a suspended ceiling. I know some lighting design/manufacturing companies sell plug and play style fittings and wiring which I think may be H05. Is there a great deal...

    Decommissoning Switched Fused Spur

    Perfectly safe to have a spur installed without outgoing cables connected to it.

    Suitability of SWA armouring as CPC

    https://gadsolutions.biz/regulations/swa-as-the-cpc Anyone know how reliable the tables on this website are for determining whether the armouring of a cable can be used as it's earth? Not too sure how old the page of the website is so could have changed since it was made or could have been...

    3 Types of Meter Tails

    Evening! Once upon a time I would use 25mm meter tails which comprised of 7 strands. I now use a 19 strand version. The other day, however, I'm sure I spotted a very fine stranded version on a page on YouTube or in a catalogue/magazine etc. Anyone know what this would have been and is it...

    Removing someone else's isolation

    IN MY OPINION... If your lock off has been put in place as cables etc were damaged and then someone has came along and carried out a temporary repair and tested there worked and signed it off in their name, in my eyes they are therefore taking on the responsibility of the work and you can no...

    Cable calc confirmation required!

    Just recalculated a recently installed cable and looks like I could have installed a 4mm 4core instead of a 10mm 4core to supply a 25amp TP fixed equipment! 4mm 4core 70m x 25A x 9.5mVAm = 16.625V (16.625 ÷ 400) x 100 = 4.15% but because I've calculated it at 230V I've ended up at the below...

    Cable calc confirmation required!

    All valid points. Whats your method for say a 32A radial to be used for general sockets which you don't know what appliances will be used? This needs designed for breaker size surely?

    Cable calc confirmation required!

    Thanks for the reply. Yes, that's basically what I've came to realise today. Three phase loads have a lower voltage drop and therefore I could have potentially been using cables with a smaller conductor size. Another thing I do aswell which I'm wondering if it's common - when Im calculating...

    Cable calc confirmation required!

    Yeah so for 400V circuits supplying 400V equipment, I've been taking the voltage drop and calculating the volt drop percentage at 230V rather than 400V meaning percentage of volt drop is actually lower and could have potentially used smaller cables saving money

    Cable calc confirmation required!

    Yeah got ya. I was just meaning for a circuit feeding three phase equipment, not a sub mains or anything
