I am an industrial electrician for a corrugating plant in Pennsylvania. We have a delta three phase, three wire system. I was wondering :roll: as to why manufacturers want a grounding rod driven in the ground beside their equipment and tied to the grounding of the service. One piece of equipment was an air compressor with a small onboard computer. At first I thought how is this grounding rod going to protect people when it is approximately 60 yards from the three phase service grounding rod? I also thought as this is to help in lowering high transients affecting the controller. There has been a couple more grounding rods driven into the ground by other equipment that doesn't have computer controls. Can you please let me know why these manufacturers want this and for what specific reason.
Thank you,
