extending cables in CU

[KashBag]

Hi
Could some one help. You come across a CU relacement job and you realise cables are too short. What would you do to extend the cables? I could think of 2 options:
1. cutting the wall to expose the cables and move the CU
2. Using crimp connectors to extend conductors.
Is there a profi system out there? Someone was talking about a rail connector system???

thank you

Push fit (Wago) connectors tucked behind the protective devices.

Wago make a Consumer Unit Relocator System. Maybe that is what you are thinking of?



They come in various sizes...

My preference would be to raise the CU if possible.

As westward, don't over complecate it, wago and tuck it out of sight

They are excellent, I have used them a few times for consumer unit relocations!
They can get a bit tight with cables if you're using all the terminals, even when dressed nicely!
