Hi. I own a large shed, currently served by 1 single socket, so need to make power points more accessible. My plan is to run two radial circuits, one down each side of shed with 4 double sockets on each circuit. Idea is to use 4.0mm2 t&e on a 32A rcbo for each circuit. Cable length from CU to last socket will be approx 44 meters on one side of shed and 38 meters on the other side. Shed is for my own personal use and will only be used to run light power tools, extra lighting, industrial vacuum, small PA system etc. Does this sound OK? Could I do it in 2.5mm2 on a 20A rcbo instead - i.e. cheaper cable and easier to connect I guess than 4.0mm? Any advice appreciated. I have no electrical qualifications, only many years of DIY jobs, so feel confident in actually doing the work but not sure on some of the technical specs etc.
