Crimping lateral mains

[jamminuk]

Hi,

Anyone here see any problems crimping 16mm lateral mains as a repair as opposed to re-running a complete new cable? I'm talking line, neautral and earth for 12 flats, 60Amp fuse. Junkies keep on nicking all the cable.

Thanks

Jammin

Are you using an SWA cable jointing kit or just exposed crimps?

 

[jamminuk]

Exposed crimps with heat shrink insulation, these are just 16mm singles LSF

If your using exposed crimps and heat shrink id be inclined to finish the joint of with self amalgamating tape(waterproof/moisture proof) or/then cloth tape also

Just to add these cables are run in metal trunking, not sure if that makes a difference. I suppose what i want to know is, is it against regulation doing it this way? Someone mentioned something about bad practice.

Thanks

I suppose a new cable is the best option but the new ammendment in the regs says we can bury joints in a wall if the joint is made with a mechanical tool, i.e crimps

Whats the regs about crimps and heat-shrink?Do you need to heat-shrink insulated crimps?

By far, ...better to enclose overall, in an adhesive headshrink tube. Those tubes when cooled can be as hard and as thick as PVC conduit, but will be sealed both ends against moisture etc!! Not that expensive either!!

No you don't have too, but i always do, and in the appropriate colours too.... Some insulated crimps have heatshrinkable insulation as the insulated cover, but i still over cover with coloured Heatshrink
