In article , .. . . . . So is it legal to connect a phalanx of ham station ground rods to the service entrance ground?? Or not. As I understand it, according to the NEC, you must have only one grounding *system* per building. This system may include two or more ground rods, and/or a bare grounding wire buried in a trench around the outside of the building. The ground rods and wires must be securely bonded together with heavy-gauge wire... that's what ensures that it's all one grounding "system". .. . . . . . . Makes complete sense and answers my basic question. Thank you David. I have five 8' ground rods already installed with more coming. All of them will be bonded together with about 100' of #8 bare solid copper. Let's try one mo This place is a "This Old House" type abode. There is no basement and no visible service entrance ground rod. There's a tight dirt crawl space under the place which I'm not about to even try to wiggle and squirm through to find the power wiring ground connection. If there is a ground it's the 3/4" copper water supply line from the street which pops up somewhere in the crawl space per normal practice in days of yore around here. I know for a fact that it's an old ~80' 100% copper line, not plastic. On the other hand the service entrance panel box is quite accessible. Would it be OK if I connected my ham grounding system to the neutral/ground bus in the panel box instead of to the water line?? -- Dave Platt AE6EO w3rv |
