Junction box for downlights

[nathanfriend]

Hi,
I've installed these downlights http://www.screwfix.com/p/lap-fixed...ntractor-pack-polished-chrome-240v-pk10/77301

I've attached 2 core+earth cable to each lamp. What sort of junction box do you recommend I use?

I plan to have two circuits, one with 4 lamps and one with 6 lamps.

Cheers,

Nathan.

If the cabling is to be left loose and not clipped, and the joint boxes not fixed to anything, then I would use Ashley J501 joint boxes.

I like these click flow junction boxes - http://www.tlc-direct.co.uk/Products/TLCT100C.html . Makes changing a fitting a doddle.

I find the click-flow ones far to fiddly and the cord grips on those 16A ones are about as useful as a chocolate teapot

Mt preference are the ashley/hagar J501 http://www.tlc-direct.co.uk/Products/ASJ501.html for downlights

But don't wire them as per the photo on TLC's site...

Yep those click flow joints are brilliant. The only trouble I have is sourcing them locally. I have to get them mail order and then keep them as a stock item on my shelves.


Ha ha that photo on TLC is very amusing!!

 

[nathanfriend]

Thanks for the suggestions. So looking at the photo I can join 3 spots to each click flow fitting?

 

[ban-all-sheds]

No, you can fit 1 - that's what the photo shows.

I think you should spend some time learning how lighting circuits work, if you think that photo shows 3 lights connected.

Ah OK

So can I avoid using a junction box at each spot and do this layout?

yup, I personally like method 3 on here, dependant on ceiling space it may well use a lot of cable, hence the but it gives you a central wiring / jb location

 

[nathanfriend]

Cable wise Method 3 is what I have at the moment although I don't know what sort of junction box would accept 7 pairs of cable.

Initially I didn't realise you could put two cores into one downlight connector (method 1). So this may be the way to go.

I know it's an old topic but I was considering wiring downlights as follows using junction boxes or Wago connectors - is this an acceptable method?

I guess so, what are the boxes with the o in the middle?

What are your plans regarding earthing?

 

[PrenticeBoyofDerry]

Something that has not been mentioned that you must be made aware of is, that any junction/joint made within the ceiling void must be accessible for maintenance, testing and inspection, also holes made within joists must be compliant to part A of the building regulations, look in Wiki under electrics-installation techniques.

Good stuff, thanks guys.

The box with an o in it is my poor attempt at drawing a junction box

The lights are double insulated so I wasn't planning to run an Earth (and there is no terminal on the casing).

Thanks for the pointer on the joists. I'll be running the cables in the loft and follow the guidelines.
