The copper cladded earth spike or stake is used to earth the electric fence system. A minimum of 3 earth spikes must be knock into the ground near the electric fence at a minimum of 1.5 m apart. Connect these earth spikes to the energizer or the fence using the high tension insulated cable (HT). In areas where earthing conditions are bad you may be required to add a few more earth spikes/stakes along the fence line and connect these back to the energizer.
