suitable j/box in loft are

driverman · Dec 9, 2014

Not a lot to day so yet another question. Got several (about 10) 1.mm lighting cables to join together in a loft space which has about 300mm + loft insulation.
Years ago I would of used a J701 j/box with chocs blocks. Anything better on the market now? Would you guys fix the j/box above the joist level and the remove the insulation so as not on top but still some underneath?

Assuming you are connecting multiple lighting circuits, i have used surewire boxes and they look very neat. Surewire - Pre-wired Maintenance Free Lighting Junction Boxes

Looks neat, thanks. Basically a few feeds L+N's + a couple of 3 core sw/wires + several cables to lights. Are those boxes pre-wired then? Would that restrict my wiring options as opposed to starting from scratch?

Why wouldn't it comply? It comes with a small mounting bracket so as not to compromise the IP rating of the box but you can still fix it securely to a surface and the knockouts are rubberised so you can poke cables through. Although they do have internally threaded sections so there is no lock nut required when putting a stuffer in there.

As Dave has said, in its current form it would not comply as there are no cable grips!

sy to use ashly jb 701 + waggo or similar connectors-just make shure the stripped cable has no kinks in it before you do the conn note cable secure with cble ties and slots in box

I've already written on them in inedible ink, better than pencil lol. But yes, be great to see what you use.

Does that stop the mice eating the cables?

Yes they are pre wired, i have found no restrictions with them. The only downside being that with the short connections on the push fit terminals, if the wires are connected it is hard to tell if one is loose, just takes a little extra checking.

I clip the cables once the box is secured.

Although i have been guilty of leaving jbs loose(ish) in certain situations. I only use glands with Wiska boxes when they are either on show or in a potentially damp environment. Because i am a tight arse!

Good point but I've not come across it

It's crap mate. I used it on a rewire then spent 20 minutes identifying the seperate conductors. At least with standard brn/blu you know which is your switch feed and return.

Nice idea but pointless. I am probably going to end up using it as standard t and e and sleeving one of the browns blue lol
