Okay here's a stupid question...... My neighbor DIRECTLY on the other side of my wall has his utility box there next to mine. So if he has HIS OWN ground rod next to mine, this isn't an issue with the ground loop problem but me doing a 2nd ground rod 15 feet away is ?? So this star topology thing would imply they'd have to be connected somehow to be safe.....correct?? I know there's more ground rods 40-50 feet away too......or less. This is why I'm confused to all hell.
