Setup: 320/400 meter pan. One service drop. Two main 200 amp panels fed from meter via conduit. Panel A would be on one set of service entrance cables 40’ from meter. Panel B would be on second set of service entrance cables. 230.71 and 230.72 seems like the applicable section. I don’t think...

I've got a client who doesn't have all of his service disconnects in one group, on his Bed & Breakfast, but says it was redone about 12 years ago. Does anyone know when 230.72 (A) required this? The last Codebook I can lay my hands on is 2002, which required it.
