UK Insulating copper tube splices

[John-]

Hi, what are people using to re insulate a copper through crimp In a metal adaptable box please? Also my SWA CT650H crimp tools don't want to crimp splices - E.g On the 10mm setting a good tug and the splice falls off, setting to 6mm will crimp nice and snug. But thats not great. Any guidance on this also please would be appreciated.

cheers

Several layers of a decent heat shrink, what do you use?

Heat shrink, gone are the days where a few layers of tape would be ok!

Don't know about the crimping issue, perhaps try another brand of splice crimps?
Personally like Pete, several layers of heat shrink but have seen joints within short length of pvc conduit and also 'self amalgamating' tape used, which presumably becomes a solid insulation and not a tape!!!

I rap a good layer of insulation tape round it the cover with heat shrink. Just remember to slide the heat shrink over one end of the cable before crimping it together

since when ? red , black, or green. all available from local DIY store.

Some people argue that tape does not comply with 416.1 as it can be unwound.

Thats what i have done. I used some very thick clear stuff i got with a load of Robus LED strip. Not got much left. Do you have a link for the stuff you use please?

Self amalgamating tape for me. Not as pretty as heatshrink, but one size fits all, and can be wound on afterwards

Looks like this could be good:
