What is a common material used for grounding conductors?

• A. Aluminum
• B. Plastic
• C. Copper
• D. Wood

Answer: (C)

Copper is the most widely used material for grounding conductors due to its excellent electrical conductivity and resistance to corrosion. These properties ensure that a grounding system effectively carries electrical faults safely to the ground, minimizing the risk of electric shock or equipment damage. Moreover, copper is durable and can withstand various environmental conditions, making it ideal for outdoor applications where grounding systems are often installed. Its ability to form a stable connection when joined with other metals is crucial for maintaining effective grounding over time. While aluminum is also used for grounding in some applications, it is less common due to factors such as higher resistance compared to copper and the propensity to corrode when exposed to moisture. Materials like plastic and wood are not suitable for grounding conductors because they do not conduct electricity at all, and hence cannot serve the purpose of grounding, which is to provide a low-resistance path for electrical faults.
