Looped in ceiling rise - adding junction box/spur

[Scatts570]

Hi all,

I’ve fitted some Ikea light activated wardrobe lights and fed the cables through the ceiling into the loft. The lights are 24v dc and are fed by an Ikea 240v ac transformer. They are switched on by a photovoltaic sensor. My thought was to cut the plug off the transformer and wire into the existing lighting circuit at a junction box in the loft. There’s no JB’s as it’s looped in at the ceiling rose.

My question is, can I just cut the cable and fit a junction box in line and spur off to the wardrobe lights so I have a permanent live to them?

My gut says yes, but whilst I did electrics in my youth on aircraft, I’m not familiar with domestic regs.

Would appreciate some clarity on this.

Yip what you are proposing all sounds good to me, providing it is all done to a good standard, for example earth sleaving used, no single insulation outside the box, connections good with no exposed copper, I like the box secured and labelled.
I have just done a similar thing to upgrade my bathroom electrics as I have added a fan and a heated mirror.
Safe working practice as well obviously like isolation of circuit before working on it.

Thanks Roys. I was 90% sure, but always worth checking with the experts in case I’ve missed something.

Just in case the lights ever go wrong and a point of isolation, why not instead do as you suggest but instead of a junction box, fit a 5A 3 pin socket and plug the lights into that with a 5A plug?

Or just fit a normal single socket, so no cutting off plug and invalidating the warranty.

Hi all,

Sounds a perfectly reasonable method to me?

The only word of caution when extending off looped in & out lighting circuits..
Is make sure you have correctly identify a permanent live cable..
Not Live & Switched live cable looping off to a light switch..

I have had to correct DIY alterations before where a customer had tried to supply a new light off a switch cable..
mistakenly assuming that all cables had a live and neutral!

Side Note:-
If you are not aware, WAGO connectors are your best friend when doing wiring alterations..
e.g. https://www.tlc-direct.co.uk/Manufacturers/Wago_Connectors/Wago/index.html
(numerous other suppliers are also available.. google is your other friend)

But basically don't faff around with outdated screw-terminal junction boxes!
