Crimps inside the CU

[seftonbarn]

I think I have gleaned sufficiently from other posts that it is acceptable to use good quality inline crimps to extend cables for terminatingwithin a newly installed CU. Invariably,for 2.5mm T&E and 1.5mm T&E these crimps will be red in colour. I ask the experienced electricians on this forum: is it best to cover the crimp with suitably coloured insulating tape or left as it is?

proberbly be better with WAGO's

 

[seftonbarn]

Thanks. Probably better with Wagos or easier with Wagos?

Or heatshrink over the crimp. If you want to be super duper

 

[bugsy]

Easier with wago's and better intregrity

Blue for 2.5mm and Red for the 1.5mm.

Insulation tape is best left in the wholesalers - pointless. You can heat shrink if you like but no need

No, ...Never use PVC tape on crimp connections always use heat shrink!!! For an even neater job you could use bare crimps with 2 layers of heat shrink to insulate them. Or you can buy heat shrinkable insulated crimps. For aesthetics sake, i always like to see the appropriate core coloured heat shrink over crimp connections...

I would use Wago/Line connectors. No need for additional insulation inside the CU.

If you use the uninsulated ferrules crimped with a decent indent crimper and put 2 layers of heatshrink over it makes for a more streamlined joint.

long time no hear , thought you might have "defected".
glad you back anyway as i'm bored of having to be polite in your absence ;-D

Personally I would shudder if I saw wagons in a cu instead of a crimp

amen brother !

When you've finished shuddering and wobblying please explain why ?

Haha, no. Just a large job which has meant long days and little time for much else.
Glad you missed me

Because they will look like a bloody armature has been at work. Nothing wrong with Wago's, they just don't sit well being used in a CU!!!

It may look untidy, but a wago is always a superior connection on solid core, to a crimp imo....

Only in your world!! lol!!! Once a solid core has been de-formed within a crimp, you'ld need to be a ''Desperate Dan'' character to be able to pull it out!!
