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....
 
here you go, from an RS document:
Red: 0.25 - 1.6
Blue: 1 - 2.6
Yellow 2.7 - 6.6
 
Thanks for the help!!
would it also comply if i were to use a joint box with screw terminations placed in the floor void if i gob the enclosure up with a compound?

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

hager ashley boxes all the way.

dont you think a heat shrink wrapped bunch of cables under the floor looks a little amateurish ! ?
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
