Ok I have an electric fence behind my house. And next to it is a small building that has a lamina roof. I would like to electrify this roof using the current from my fence. Does anyone know of a way to make this work right. From what I know there has to be a ground output for the electrification to work right, that's why the fence works, when you touch it your grounded. But if someone or an animal is on top of the roof it won't go off since there is no ground, right? Or am I thinking about this too much? Thanks for any advice you can give me.
