I would like to run an overhead wire about 100 feet from my home to a chicken coop to power a light (15W CFL) and a small timer. My preference would be to tie into a junction box already in place under my deck (about 9 feet off the ground). What kind of wire is needed for this? Do I need a neutral wire rope for support, or can I use insulators on posts? Is 10 feet an adequate height for the wire? (It will not be crossing over sidewalks or any other existing structures.) Thanks for your help!
