This is my most recent setup. A hot wire fence, within a hot wire fence.

This one is a single wire, intended for crowd control to keep the new kids confined to quarters....free to roam about within a garden area setup special for them. So far, it is working. In the three days it has been working, none have been found outside the wire. I've not seen anyone seriously get it (one got tickled), yet only they go up to it, stare at it, then back off. How would they know?
Anyway, basic setup is like this. One single hot wire, connected to a fence charger, which in this case, is powered by a 12 volt deep cycle battery. No solar charger. Unless it is grounded and shorts out, a single charge will last nearly 2 months. So no need to tether to an AC outlet. In this case, the ground is the steel T post that also serves as a corner post for the poly tape fence.
That is a 0.6 joule charger, which is delivering 7,000 volts+. As per this maker, that is plenty to deal with almost all animals. Should be enough to whack any coon, dog or other varmint.
My other charger is much hotter.....13,000 volts+. This one....

To run such a wire around an existing fence made of some type of woven wire and perhaps steel posts, the woven wire and steel posts can be connected to the ground or (-) side of the charger. The single hot wire runs along top. Assuming the animal is forced to climb the wire fence to get over it, the hot wire waits for them along the top. So while standing on the ground wire, they touch the hot wire and it lights them up.
If it is a board fence, or something that will not conduct electricity, then you have to run and adjacent ground wire to ground them. Exactly like Connie shows.
