Morning all
I have been asked to wire a integrated garage that is being converted into a Kitchen/dining room. there is an old wylex 4 fuse board in there at the moment supplying a 32amp ring and 6amp lighting circuit to an upstairs bedroom and a 32 amp ring and 6amp lights in the garage. there is also a SWA feed (think its 1.5mm) to a shed that has its own main switch off this board. this is all being supplied by a 10mm2 swa cable from one of the home consumer units (fed under floorboards no RCD protection at this point).
so what I have been asked to do is remove old garage circuits, leave the ring and lights for upstairs (this is for one bedroom only), add feed for 7.7kW (max) oven, Ring for 7 double sockets, lights ( 8 down lighters, 2 ceiling roses), feed for under cabinet lights and a feed for outside lights to be installed at a later date.
so the bit that is starting to confuse me is ( been think about it far to much, customer is old industrial sparky and is saying it should be fine) will the existing 10mm2 feed from cu be sufficient the run is no more than 15meters long or do we need to upgrade to 16mm2 swa. and I guess I will need to put in an RCBO in on the source for the feed in the house cu board.
Too much Xmas food and beer scrambled me brain lol!
Cheers guys
