What is one reason to avoid using tie wire for ground rod connections?

Using tie wire for ground rod connections is often avoided due to its susceptibility to corrosion. Grounding systems are crucial for the effective dissipation of electrical energy during lightning strikes or power surges, and the integrity of these connections is vital for safety and performance. Tie wire, especially if made from materials that are not corrosion-resistant, can degrade over time when exposed to moisture, soil, and other environmental conditions. This corrosion can lead to a weakened connection, reducing the effectiveness of the grounding system and potentially creating hazardous situations.

In contrast, other materials specifically designed for ground connections, such as copper or galvanized steel, offer better resistance to corrosion and ensure a more stable and reliable grounding system over time. Therefore, the choice of materials in grounding applications is critical for maintaining safety and system functionality.
