Question: 1 / 400

What is a common material used for grounding conductors?

Aluminum

Zinc

Copper

Copper is a commonly used material for grounding conductors due to its excellent electrical conductivity and resistance to corrosion. It provides a low-resistance path for fault currents to flow safely into the ground, minimizing the risk of electrical shock and equipment damage. Copper's durability and ability to maintain its conductive properties over time make it a preferred choice for grounding applications in various electrical systems. Additionally, copper is less likely to degrade compared to other materials, ensuring long-term reliability in grounding installations.
