Which material is commonly used for grounding electrodes?

Copper is commonly used for grounding electrodes due to its excellent electrical conductivity and resistance to corrosion. These properties make copper highly effective in ensuring a reliable and low-resistance path to ground, which is essential for the safety and functionality of electrical systems.

Copper's durability and low maintenance requirements contribute to its suitability for grounding applications. It can withstand harsh environmental conditions, which is crucial for maintaining effective grounding over time. Additionally, the use of copper in grounding systems aligns with various electrical codes and standards that specify materials needed for effective grounding practices.

While other materials like steel have certain applications, they are less preferred for grounding electrodes because they can corrode and may not provide the same level of conductivity as copper.
