Hi all, just put up a new shed yesterday, and want to get an electrical supply to it. Only for a light and double socket. There is an outdoor junction box on garage wall, where electrician took feed from fuse box to garage, and the SWA joins to t&e in there. Would it be permissible to run a 4mm SWA cable from here to shed (approx 12m), clipped to garage wall? Cheers!
