BUY HERE! Lightning will damage your electric fence energizer if it strikes your power fence. Gallagher energizers have internal lightning diverters that give partial protection against small strikes. Installing an Adjustable Lightning Diverter (G6480) will give added protection by providing a path for the lightning that strikes the fence to be diverted to ground. Otherwise disconnect the energizer from the fence and power supply during lightning storms.
Lightning always finds the easiest way to earth. In areas where lightning is a problem installing an earth system to include a lightning diverter earth is essential.
