Re: about grounds… a New Discussion

[George Handley]

Warren,

Maybe in the city versus a rural situation with a distant run to a shed am I told an additional grounding (Additional to the utility ground) rod might be OK to use. I've been specifically told that installing an additional grounding rod here, say in my basement to the breaker box would REALLY screw things up, but I regret to advise I can not explain exactly why, except that it sets up two grounds which might start carrying voltage… I think.

Anyway, my four breaker boxes neutral and grounding bus bars are interconnected, and the whole thing is connected by bare copper to the utility's pedestal.

Also, failed to mention, that my ground is NOT connected to my incoming water service like I've seen other places in the past.

I'll bet this still flies against what you and others have recommended.

Thanks,

George

> George, one small correction. I didn't post about not taking the ground to a sub panel. I have done that here to my shed and also drove a ground rod at the shed sub panel which is terminated in the sub panel's grounding bar. I think someone else commented about that part. As to terminating your #6 solid copper to your panel ground bar: Yes, you must do this regardless of your utility having a ground at its transformer that should be bonded to their neutral/common wire of a 230VAC single phase service. I'm sure as far as grounding might go it is possible to get too much of a good thing but over the years I haven't seen this.
