Hi everyone I've been out the business a long time and am rusty on regs. Perhaps someone can assist? My son has an armoured cable fed from his house CU via a dedicated mcb to his detached garage. This cable is connected to a 'Lewden' 'garage' CU consisting of a 6A mcb feeding two small flourescent light fittings and a 16A mcb feeding one double switched socket. He uses several rechargeable drills/tools etc in his job and currently uses two 4-way extension leads to recharge everything. I'm proposing installing four additional double switched sockets and returning to his garage CU to change the feed to a ring. I appreciate this means I need to change his 16A mcb to a 32 A mcb. To save changing the 16A for a 32A, is it within the regs to simple add four more sockets i.e. have five in total on a single cable?
