A friend of mine wired a 10mm 3 core armoured cable to his shed before I got involved and wired it himself already. He wants make it an air bnb with a ring circuit 32a, lighting circuit 6a, induction hob circuit 32a and a underfloor heating circuit 20a. Will the 10mm be enough for the supply and what size breakers would people recommend? For the mcu feeding the shed and the mini board in the shed? Thanks
