If no pole ground is present when setting up protective grounds, what should be done?

When no pole ground is available during the setup of protective grounds, running a jumper from the cluster bar to a driven ground rod is a critical safety measure. This approach establishes a reliable grounding path that can effectively redirect fault currents safely into the earth, minimizing the risk of electric shock or equipment damage.

Using a jumper in this way ensures that the electrical system has a defined point of grounding, which is essential for maintaining safety standards and preventing hazardous conditions. This method aligns with standard safety practices, emphasizing the importance of establishing a solid ground connection whenever working with electrical systems, especially in situations where existing grounding options may be inadequate.

Other options may not provide the necessary level of safety or might bypass critical grounding protocols, potentially leading to dangerous scenarios during electrical work. Therefore, utilizing a jumper to create a proper grounding solution is the most responsible course of action in this situation.
