    Lightning Diverterhttps://am.gallagher.com/us-en/products/electric-fencing/power/power-management-tools/safety-and-protection/G64800Lightning DiverterGallagher recommends all permanent Energizers be fitted with a lightning diverter to help protect from lightning damage. The Lightning Diverter has two terminals for attaching wires and leads from each terminal that are set with a wide enough gap to prevent the normal energizer voltage flow from arcing across, but close enough to allow a lightning voltage spike to jump easily across and pass to ground.
