Grounding wire, also called earth or earthing wire, is used to complete an electrical path to ground in the case of a neutral conductor failure.
A polyvinyl chloride (PVC) ground wire is used to create an electrical path of resistance, allowing electrical current to safely reach the ground during a fault.
In the U.S., PVC ground wires can be bare copper or insulated with green, green/yellow, or black PVC. PVC insulation is suitable for use in a wide range of temperatures, and is heat, moisture, chemical, and abrasion resistant.
