A P74 Lightning arrestor kit is recommended to minimise damage to your energiser. Lightning always finds the easiest path to ground. Therefore the ground system of the lightning arrestor must be as good as or better than the energiser ground.
The Lightning Arrestor is fixed to a post near the beginning of the fence line and helps to prevent the mains fencing unit being struck by lightning.
The top terminal is connected to the fence line and the bottom terminal to an independent earth stake.
