Like your thoughts here!! Keep up the good work!!
I would "guess"
that the only cons to this would be:
1: Grounding on the "Line" side of the meter,
2: Not a single point to bond the grounded conductor, the service equipment and the equipment grounding conductors to the Grounding Electrode System,
3: Point to disconnect the GEC from the Grounded conductor ["Neutral" Disconnect Link] would not be easilly done if that test was needed.
These items would be the ones to start flame throwers and Napalm going, but to me, I think you're on to something!!
But you know me, I'm very controversial on the whole Grounding Electrode situation
Would be great to get a "Grounding Electrode Design Thoughts" thread going - maybe it will take off!!
P.S.: Love that intro!! "I'm bored with the same old grounding" - Rampant boredom like this will make jack a dull boy
