Splitting 25mm meter tails to SWA and 25mm tails

[Grayza]

Hi All,

I need to split the meter tails to supply a second CU which will be at the rear of the house, however the supply to the second CU will need to be in SWA and I can only split the tails at the meter cupboard. Is there a suitable adaptable box or isolator I could use to be able to do this?
Thanks

That is a lot of work for a new ring and a cooker circuit!
It sounds like you have ruled out using the existing consumer unit. Is it full? Does it have a cooker circuit that will become redundant that could be re-used for the new?
As Davesparks said, could you not extend the existing ring, it would be far easier. In fact I cant see how you can fit a henly and metal switched fuse in the existing meter box, so unless you are going to fit a new meter box you cant do it. You may be able to fit a KMF switched fuse in there but then you would not be meeting the regulations.

Is there no cooker supply or available socket circuit to extend to the new positions?

Yes there is but the existing house CU has no RCDs and they don't want me to upgrade

Sounds like a job to walk away from then. Can't win them all.

Anyone replaced a CU like this, recessed in the wall and coving (Coving has even stuck on the outside of the CU door, to match in)?
And if you did what board did you use?

wow, that is a difficult job you have there! I can see why you were trying to split the tails now.
I think you have to just give the correct options to the customer and if they don't accept any of them then you decline the job. They will get someone else to do it who will not stick to the regs but your morals and PL insurance will be intact.
The options that I can see are:
New meter box by the side of the existing.
Replacement Main consumer unit.
Additional 2 way consumer unit next to main consumer unit that feeds sockets and cooker.

I'm sure you could play around with the gap you have behind the existing consumer unit to fit a modern recessed board into it. Perhaps not easy, but doable, plus you charge accordingly.

Cheers Happyhippydad, you have suggested one option I hadn't thought of, second CU next to existing, my mind was on how difficult it all looked.
I'll give the customer the options and see what happens.
Cheers everyone
