Woooo, something i know about so i dont have to log on, read, then log off
Depend on how far away your shed is.Like mango I'd use 4 or 6mm but 2.5's fine. e.g- 1.5swa can take 27A clipped direct so 2.5 is fine. Stick a 20A mcb on it and youre well within limits.
Use 3core and sleeve one core with earth sleeving or green/yell tape. This means if you dont get a good connection onto your external braiding you still keep a good earth. Use the earth washer tabs in the gland packs, they are there for a reason
Oh and use waterproof glands, they are pennys more and make a better job.
If your putting a little fuseboard in garage make sure at least the socket is protected by rcd. If your not, make sure the mcb in the house is protected by an rcd. Even better an RCBO.
Also, you do know that any work in 'special locations' is supposed to be notified to building control. Google PartP. Heaven forbid you would ignore it
