Am I being stupid

[Redvanman]

Ok I know you guys are shy at coming forward but tell me what you think,

I have some LED floor lights to be put into a tiled bathroom floor.
The cut out size is 20mm and the flex on the light is 1M therefore I was thinking of crimping the flex to T&E under the floor and heat shrinking it so that the cables will run to a JB outside the bathroom.

Any better ideas would be appreciated

And to think I just thanked you

Bull, red rag mate sorry, too good an opportunity to pass up

No driver 240v sealed unit

I've installed some in our new kitchen - they look really cool!

I would recommend soldered over crimped, the problem with crimped is they can generate quite a bit of heat.

had one a while ago that had the insulation tape burning

Must of been a badly done crimp then....

I'd probably join like for like, ie extend the flex with flex, not T&E.

Or a bit of damp got in there and interfered with things.

 

[Redvanman]

Heres one for you Mr M

Could you shorten the flex from sealed unit so that you can access (crimped or other) joints by removing sealed unit, without having to pull 1m of flex out?

Maybe if you use cheap crimps and crimpers that you can pick up in Argos... I use good quality crimps and knipex crimpers that cost £100+, I know my crimps are good solid connections. They are heat shrink glue lined and I put a length of glue lined heat shrink over the three crimps to enclose them all.

we are talking 35mm tails here.

well 35mm to 25.

I was set against it and had already ordered the cable (35mm like for like is best) before being told to use 25mm they already had.


for normal red, yellow and blue crimps my silverline crimpers are fine. I was suprised how good they were to be honest.

Never had a butt/through crimp fail on me yet, but then i don't use those bulky coloured PVC covered butt crimps. I use either the coloured heat shrink butt crimps, or plain crimps followed by two layers of heat shrink tube....

spiffing good idea, what. as long as there's enough slack on the incoming cable to the joint, can't see a problem as long as the joint will pull through a 20mm hole
