Shed power

Posted by Steve Harber, on Thu 05 Apr 2018 11:44am

Hi, After some advice please. I have run some armoured cable from the house down to my shed (roughly 10m away). There is a garage CU in the shed with a 6A breaker for lights and a 16A breaker for sockets. Do I need to wire the sockets as a ring circuit or a radial circuit? The armoured cable is spurred off the house ring main and has RCD both ends of the cable. I don't intend to run anything of high current from the shed, just power tools and maybe a small heater. Since the supply to the shed is only a spur, is there any advantage of running the 4 sockets in a ring or will radial be ok?

Hi Steve, Firstly you need to establish what kind of load you will be drawing from it. If just casual light stuff ( the odd lawn mower, battery charger etc.) you can spur off the existing house circuit with a 13amp fuse as long as the existing ring is RCD protected. If however you are drawing high current it would be advisable to in 6mm SWA cable or 10mm, directly from the existing CU to another. From what you have described I would go with the fused spur running the new sockets as radial Hope this helps Connor C.K plumbing services
