For about the past week and a half to two weeks I've been dealing with Mama pig breaking out of her area in search for greener grasses. The Energizer that's running her electric netting is not pushing out enough electricity to give her the shock she needs to stay back. I bought this Energizer from Tractor Supply and it says it pushes out 1.2 to 1.6 joules. These electric nettings need anywhere from .5 to 1 joule to reach 8000 volts. So you would think this Energizer do fine. But it's not. I've heard from people that the energizers at Tractor Supply don't work as well as the energizers you buy from Premier one. So I order another one from Premier one.
