Evening. I have an IP66 outdoor socket on the side of my house. To power a feature in the garden, i need to plug it in, but this will mean the cable is theoretically exposed to the public on public land, if i attach the cable to the side of my house, untill it gets to my perimitter fence where it can go into my garden. Can this be done legally or do i need to buy some metal tube conduate to put it in, along my wall?
