UK Are blue through crimps allowed on ring circuit.

[David345]

I'm a trainee electrician and I was working with a qualified electrician extending a 32A ring circuit and we were using 2.5mm single conductors (CPC was 2.5mm aswell) going through PVC conduit and then going through steel trucking.

And to connect the old ring conductors with the new extended ring conductors the electrician used blue through crimps to crimp the new and old conductors together in a small separate steel box connected to the steel trunking.

I said to him aren't you supposed to connect them together in some kind of juction box instead for a better strong connection and he said you don't need to.

So I was wondering if using blue crimps or just crimps in general to connect conductors together is ok and within the regs because I'm sure one of my college lecturer told me a few years ago that you can't do that.

I'm just curious is this allowed or not.

Thanks.

Perhaps I should run a course. 'From blue butts to bellhangers in 10 easy lessons.'

You might find other, er, speciality forums who would be very interested in a course of that title!

Sounds cold and nasty, whatever...
