cable jointing

[goldie]

Where cables have to be jointed e.g spurring from a ring final via a connection under the floor void where it will not be readily accessable in the future. What would be the best way to joint the cables as i understand a screw terminal junction box will not be acceptable .

Also crimp connections in a c/u. does it matter what colour crimps are to be used aslong as they are within their current carrying capacity. So for instance could i use yellow crimps for 1.5 mm2 t+e on 6amp m.c.b.
Thanks

Best use a joint box with push fit connections as these are maintenance free! Can get them at any wholesaler.

Use red through crimps for 1.5 t&e, blue through clumps for 2.5 t&e and yellow through crimps for 6.0 t&e.

Crimp join and heat shrink but you should use the correct size for the cable, red up to 1.5, blue 2.5mm and yellow up to 6mm

I have used Line Maintenance free junction boxes (forum sponsor...) and like them.

For crimping I'd use blue or red on 1.5mm2, can't remember the size for yellow but I suspect it is too big for 1.5mm2. (4 to 6mm2 rings a bell?)

EDIT: Monkey beat me to it....

No as it has screw terminations.

If you want to use a jb you really should try those line ones from the forum sponser, i haven't used a screw terminal jb in years, the line or wago are so easy and they are mf

I have to say that for permemant underfloor applications you can't beat the Ashley Hager products.

Not if you do it properly and offset the crimps so they're not all in one place and make the cable look like a snake thats eaten a buffalo

Why do you say that?

 

[Octopus]

Why do you say that?

Because I like them, use them, my local trade counter keep them and keep a few to hand in my wheels. Simples.

 

[telectrix]

the line enclosures are cheaper, quicker, have twice the room inside, and if you want to fix to a joist, a cable tie and mount do the job. for me it's line all the way . ( freebie by 1st class post, please, mr. line! )

Thats personal preference so fine, but why did you say they cant be beaten?

For LINE MF lighting set it will cost less than £1-50 and I challenge you to a case of beer that LINE will be quicker too!

 

[telectrix]

£1.73 to be exact. i've just ordered 25.

If you want to include the taxmans share yes. £1.44 before) But then you need to add 20% to the wholesaler prices quoted above too!

(PS: you can forget the 1st class sample now :wink_smile

I get 3 - 4 jobs per month via my local trade counter - why would I want to loose this. And while I'm making a point I buy Wago's locally too for a similar reason. My business is based on local service to clients and where feasible I source locally too.
