Looking to get power to my shed, I have installed a duct to it already , it’s 45m away from property, my plan was to run Said length of cable from house which will have a normal plug on it, plugged into a rcd plug then plugged into a socket in the house, the other end wired into a small consumer unit to run a tube light and a couple of double sockets. I was thinking of using 6mm or 10mm would this be ok? is there any possibility over overheating etc. Looking to use just a kettle , power tools maybe lawn mower. thanks
