Ground wire completes the electrical circuit if the neutral conductor fails because of a fault or short circuit. This wire connects to the earth to create a resistance path, allowing electrical current to reach the ground safely and discharge excess electricity.
Single conductors are stranded, annealed or hardened, tin coated or uncoated copper.
Conductors are insulated with a concentrically applied green or black HMWPE (high molecular weight polyethylene), or green or tan PVC (polyvinyl chloride).
Print legends on the wire include the manufacturer, conductor size, voltage rating, UL symbol (if applicable) and type designation. Standard length spools are 500 or 2500 feet.
