What should be done if objectionable current is detected due to multiple grounding connections?

If objectionable current is detected due to multiple grounding connections, the appropriate action is to modify or limit the connections as permitted. This approach is essential because multiple grounding connections can create parallel paths for current flow, potentially leading to ground loops or other issues that can cause safety hazards, equipment malfunction, or interference in electrical systems.

The practice of modifying or limiting the connections allows for the establishment of a more effective grounding system. This might involve redesigning the grounding strategy to ensure that there's a single point of connection to ground or employing techniques that mitigate the effects of objectionable current while still adhering to electrical codes and safety standards.

This choice emphasizes the importance of maintaining a safe and effective grounding system, which is crucial for protecting both the equipment and personnel from electrical risks. It reflects a responsible approach to managing grounding practices, ensuring that the system operates effectively without introducing potential electrical hazards.
