Barn conversion

[simbin]

I've recently been approached to do the electrical installation on a barn conversion, no problem straight forward! The problem is getting a supply in. The owners want to have the mains coming from their cottage about 23 metres away. They don't want the driveway digging up for a new supply as its only just been block paved. Is there anyway of separating the supply in the cottage or do they need a site visit from electric supplier to determine whats required???

Is this to be a seperate supply metered by client /DNO

Their not bothered about a separate meter (don't know why?), just a main supply.

swa on cat wire between the two buildings easiest option

And the power comes from???? Split meter tails in henly block?! Surely 100A fuse can't supply two consumer units??? (cottage & barn)

Henly block 63a switched fuse - calc the loads / diversity

Depends what's going in the barn and how big it is

Its not too big-kitchen,lounge,one bedroom,bathroom. All electric, no gas. 3 panel heaters,hob, oven. SO.....25mm tails from isolator split in a henly block to feed consumer unit in cottage & metal clad switch fuse with swa on out going side is fine??

Providing all calcs work out, should be fine, is the cottage a PME or TT supply?
