New build, garage, studio flat above.

driverman · Apr 5, 2015

Appreciate your thoughts on this please. New build house, 1 x double garage with studio flat above. The studio flat above will be self contained with small cooker, Imm/Htr etc.
1 Phase PME supply at house. All circuits RCBO's except U/G SWA cable to garage / studio flat. SWA protected by MCB only.
Normally I would fit consumer unit in garage as per norm. But this situation, I'm thinking taking the SWA cable to consumer unit within the studio flat (on top of the garage) then from there using SWA cable to the garage protected by a MCB only.
All circuits within the flat will have to be RCD protected, but I don't want the SWA from there to the garage RCD protected. All circuits within the garage will be RCD protected. The idea being flat and garage electrically 100% separate. Person in flat will have no access to garage.
Hope it al makes sense. Thanks

First things first, is this garage/studio flat attached to the house or separated from the main house?? What's the size of this existing SWA cable that's been installed and how many cores??

Detached garage, as stated earlier u/g SWA to garage. 16mm 2c SWA used + 10mm earth wire.
