I'm nearing the end of my garden room build and planning on laying the SWA this weekend. Have got an electrician lined up to do the checks who had suggested 6mm SWA.
The distance from the house CU to garden room CU is about 15m so not a huge distance and dropping some numbers into a calculator here suggest that 2.5mm would be Ok.
The plan was to hook the SWA up to a 32A MCB on the household CU and run a 32A ringmain and 6A lighting circuit in the garden room. No really heavy machinery, probably total 6kw max which is roughly 26A.
I'm trying to do this fairly cost efficiently so don't want the 'belt and braces' of a 6mm SWA if I don't need it. Do you think I'd be ok with 2.5mm?
