Relocation of consumer unit

Kopboy · Jun 11, 2022

Hi guys
I’ve been requested to replace a consumer unit but will need relocating lower within a tight cupboard.
I will be installing a box with din rail and terminals etc and running new cables to new unit.
Problem I have is that the meter and isolator is mounted on a board. The only way to reposition the board to acceptable location is to run cables behind board.
I know it’s not great practice but no other possible route. Just wondered what your opinions are.
Cheers guys.

Does it really need relocating.

The outgoing final circuits from the new consumer unit will almost certainly be RCD protected so having them 'buried' isn't really an issue. I'm assuming safe zones are created by the new CU or your joint box?
The only real issue is extending and running the incoming supply. What cable are you running the supply in? If T+E could you put a plate on front of the board so the supply is mechanically protected?

EDIT - read it again now and realise you aren't moving it very far so will probably be tails from isolator straight in.

I know work is work, but I dont see the value add to this task.

Hopefully the OP will clarify the actual purpose.
Only two logical reasons are coming to me - It might be that an old Wylex needs changing and there isn't room in original location.
Or it might be that the original position is not able to be reached by an elderly customer.

Unfortunately yes. It’s not far from the ceiling and the ceiling is sloped. It’s a struggle to take the cover from the existing

So how far are you moving it that the circuits need extending.

About a meter lower. All the existing cables enter the rear of unit.

It is an old wylex with limited space and also the customer is old and can’t access where it is. You were right on both counts!!! Lol!!!
