Can I put a hot wire on it?
Yes you can. The entire vinyl post is an insulator which means you won't need any special hardware.
All you have to do is drill a hole in the posts and string the wire through.You should probably use a wire that is resistant to rust and corrosion.How do you set the posts?
The posts are set in concrete in the ground from 24 to 36 inches deep and in some cases cement is put inside the posts with re-bar for exceptional strength.
(This is not recommended for livestock because it makes it too strong.)
