What is the method called when a complete grounding set with a cluster bracket and personal jumper is installed at the worksite?

The method referred to when a complete grounding set with a cluster bracket and personal jumper is installed at the worksite is known as single-point grounding. This grounding technique ensures that all equipment, structures, and personnel in the work area are at the same electrical potential, which is crucial for safety in electrical work.

By using a single grounding point, the system minimizes the risk of voltage differences that could lead to dangerous electrical shocks. In this scenario, a cluster bracket is typically utilized to efficiently connect multiple grounding conductors to a single ground point, while a personal jumper provides a direct path for any fault currents, ensuring personnel protection.

This method is particularly useful in high-voltage environments where safety protocols are paramount, as it reduces the likelihood of hazardous conditions that could arise from multiple grounding points.
