Installing safe electric fencing involves buying the right charger to adequately electrify the fencing around the enclosure. An electric fence tester should be used to make sure the charger is providing a shock that is strong enough to discourage valuable stock from coming in contact with the fence. A weak current may not be enough to prevent animals from getting tangled in the fence while reaching for grass outside the enclosure.
There are various types of electric fencing material available including smooth wire and nylon cord or tape impregnated with metal wire. The safest kind of horse fencing is the tape or thicker cord because it is highly visible. The smooth wire is less expensive and easier to install, but serious deep cuts can occur if a horse accidently becomes entangled in the fence. According to Farm Supply Store, visibility flags should always be used on electrified wire fencing to prevent injury to animals and humans alike.
