new electricity supply

[markatherton]

A friend is building a new house in his garden. The garage is about 20 metres from the new house and there is a underground duct between them. The local electricity board have terminated the supply with their meter in the garage. The ccu will be in the house so does this mean a hefty two core cable to take the supply from garage to ccu, I say hefty as meter tails are 16mm these days I understand. His existing house has overhead supply with TT earth, the new supply comes from a pole over the road,underground to the garage so assume he will also have a TT earth for the new house.Any suggestions about the garage to house cable?

Is the old house staying up, or is it being demolished ?

You would probably be better applying for a new supply to the new house, but it will cost you... You should get away with the VAT component though because its a new build.

Unless you get a seperate supply, you will more than likely have problems getting the existing supply split and metered seperately (there will only be one MPAN for the existing supply, and they shouldn`t normally put a meter at the end of someone elses` submain)

AFAIK thats much too far for meter tails.... The CU should be within a couple of metres of the meter.

I think you will find that all new installs must be 25mm tails.

I think that`s only under the customers' side of the installation which would be covered by the 16th Edition - the supply regs are less strict and 16mm is still permissable afaik

Where do you want the CU to be ? If you want it in the house, i`d imagine you`d need a fused isolator and a large enough sub-main to take the supply from the garage to the house.

That would probably be entirely dependant on the network in the area. If its pole-fed, then unless the line has been refurbished, I think it would have to be TT.

Earthing is a bit of a weak point where i`m concerned though :-}

The meter tails ARE on the customer's side, and must be supplied by the customer.

16mm drops feeding 25 mm tails
