The principle of an electric fence to keep out predators is to mount it against another solid surface so the animal can't jump over or between the wires. It's more of an electric shield than a barrier.
I have gardens that are prey to deer and bears trying to climb over the fences surrounding them. I run a hot wire against the fence about two feet up, and another wire is mounted all along the top of the fence by stringing the wire through 2 inch PVC to hold it above and away from the metal fencing so the wire doesn't ground out.
I run two rows of hot wire around my coops and runs and bait the wire with peanut butter. These installations are extremely and gratifyingly effective.
