Is a grounding electrode required when no grounding electrodes are present at a separate building served by a feeder?

A grounding electrode is indeed required at a separate building served by a feeder when no grounding electrodes are present. The National Electrical Code (NEC) mandates that all separate buildings or structures have a grounding electrode system, regardless of whether any existing grounding electrodes are in place. This is crucial for ensuring the safety of electrical installations and protecting both people and equipment from electrical faults. Grounding electrodes provide a reliable path for lightning strikes, surges, and fault currents, which are essential for the proper function of electrical systems.

The requirement also strengthens the overall grounding system, allowing voltage levels to stabilize and minimizing the risk of shock hazards. Therefore, establishing a grounding electrode in a separate building is not only a best practice but also a code requirement in most jurisdictions, enhancing safety and reliability.
