How should the grounding electrode conductor connection be made from the overhead service conductors?

The grounding electrode conductor connection from the overhead service conductors should be made at an accessible point because this allows for easy inspection and maintenance, ensuring that the connection remains secure and compliant with safety standards. Accessibility is crucial for assessing the integrity of the grounding system and making any necessary repairs or adjustments.

Connecting the grounding electrode conductor at an accessible point complies with electrical codes, which often require that certain components be reachable without needing special tools or equipment. This practice enhances safety by reducing the risk of hazards associated with inaccessible connections, like failures or degradation that could go unnoticed.

In contrast, connections made at inaccessible points would hinder routine maintenance and could lead to issues that are harder to diagnose. Similarly, making the connection at any point on the load side could violate design requirements, as specific attachment points are designated for grounding purposes to ensure proper operation and protection. Connecting only at the service's transformer limits safety redundancy, as it may not provide the most effective grounding for various components throughout the electrical system.
