How does an earth spike work? The earth electrode diverts an electrical current safely from a damaged cable, appliance, or wiring to the earth. The earth electrode is connected to the electrical circuit and fitted into the ground near the switchboard of your home.
 
Earth rods and their fittings are used to provide the interface to ground in all soil conditions in order to achieve satisfactory earthing systems in overhead and underground electricity distribution and transmission networks – providing high fault current capacity on low, medium and high voltage substations, towers and power distribution applications.
