I am not getting any responses in the grounding and bonding section so I am going to ask again here.
I am trying to understand the GEC requirements for a grouping of disconnects next to a transformer at the street, each 200 amp disconnect feeds a residence.
It appears I can have one common GEC and tap off of it to get to all the enclosures. Am I seeing it correctly that if 4/0 Al is the largest conductor then I need #4 copper as the primary GEC? I can then tap with #6 copper? It appears that split bolts can be used for the taps?
Another idea would be to run a GEC(#6 bare copper) from each enclosure back to the first ground rod, each with its own acorn. Would this be permissible?
Thanks for your time
