suitable j/box in loft are

[driverman]

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?

With that many cables to join i would use a double pattress box and a combination of wago's

I use Wiska boxes and Helleman/Wago connectors. Easy to see what you are doing and very clear. I some times print flag labels off and attach them to the incoming cables (i would with yours if there are 10 cables). I will try and find a picture of one i have done....

I'd never seen Wagos until last weekend. The ones that I saw had 2 x terminations (holes) I think on the box it sais 2.5mm. Would that of meant up to 2.5mm. I'm assuming 1 x terminal 1 x conductor only, as opposed to getting 2 x conductors into 1 terminal. I would want to connect several conductors together,, typically the Live / Neutral conductors not forgetting the CPC's

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

I usually just write in indelible ink on the outer sheath (if room) for marking cables. If big enough / room

Yep do the same now using fine tip indelible ink. Used to use pencil yrs ago but fades after a while and the eyesight not as good as it was. Even used it on metal boxes whilst fist fixing to remind me what box did what!

Thanks for that. Like the fixings! does that box comply with 17th? Or am I over thinking it too much?

As long as the cables get secured properly then it will comply

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.

Yes just saw on their site about the rubberized knockouts, looks good and on you tube re the gland idea. going back to the Wagos, would I need a whole array of different sizes? I'm very comfortable with the choc terms but I'd like to keep up to date if it makes the installation even safer.
PS is that rated at 20amp. Been looking on there site.

Cables should be securely held in place, by glands or clipping up to the enclosure etc so as not to place strain on the connections should the cable be pulled on or the JB knocked.
It is an inspection item on the EICR
