What is the purpose of ground wire molding?

The purpose of ground wire molding is primarily to protect both the wire and the lineman. Molding provides a physical barrier that shields the ground wire from environmental factors such as moisture, dirt, and mechanical damage, which can compromise the integrity of the electrical system. Additionally, this protective casing helps ensure the safety of linemen working on or around these wires by minimizing the risk of accidental contact with live components.

While other answers may touch on aspects of electrical functionality, such as conductivity and insulation, those attributes are not the primary functions served by ground wire molding. The focus here is predominantly on safety and protection, making it crucial in ensuring the reliability and security of the electrical grid.
