The ground connection electrode conductor need to be run either to both disconnects or to the meter. In NC we run it come the meter. Also if friend look at the note to 250.66 you would certainly only need #2 copper to the water pipes no 1/0.Also through 4/0 aluminum your calculated fill must it is in 360 amps or less. I frequently use 3/0 copper in this situation. Girlfriend will additionally have the same concern with utilizing 4/0 ser to the interior... Depending upon the password cycle and whether or mot you room in insulation 4/0 might not it is in compliant -- We generally pipe indigenous the key discos to the inner panels so we can acquire the 75C rating
