What material is a grounding conductor typically made of?

• A. Insulated Copper
• B. Aluminum
• C. Bare or Green
• D. Plastic

Answer: (C)

A grounding conductor is typically made of bare or green material to provide a clear visual identification as it serves a specific safety function. The purpose of a grounding conductor is to create a path for electrical current to safely return to the ground in the event of a fault, such as a short circuit. Using bare or green conductors helps ensure that anyone working on or near electrical equipment can easily recognize the grounding conductor and know its function, reducing the risk of accidental contact with live wires. Copper and aluminum are both commonly used as conductive materials for wires, but when it comes to grounding conductors, the bare or green designation is crucial since it indicates the specific role of grounding in protecting people and equipment. Plastic does not conduct electricity and is not suitable for grounding; it can be used as insulation for electrical conductors but not as a grounding conductor itself.
