For those of you who don't want to leave anything to chance, there are several styles of disconnect switches that can be used to further isolate your fence from your charger during lightning storms. This is mounted at a convenient location near your charger's lead out wires Before a storm approaches, open the switch, which will isolate the lead wires from the fence and ground bed, and unplug the charger from the 120 volt power source. Of course, you must be there to do this. But short of a direct lightning strike to your charger, it will be protected. A package is outlined below.
Lightning strikes can be quite severe and damaging.
We make no claim to be able to totally prevent this damage. However, the lightning protection measures discussed above could mean the difference between a low cost repair or total replacement of the charger. For the best protection, unplug the charger and disconnect it from the fence before severe storms.
