i have a service for a 4 unit apartment bldg. the riser is 400 amps that comes down from weatherhead into 8x8x60 gutter box. out of the gutter box, there are 5 meter sockets that feed (5) 125 amp load centers. i have installed gec on the panels to the ground rod. do i need to to install a #2 thhn from the gutter to ground rod. the 4" riser is mounted in a myers hub and the meters are connected via offset nipples. by the way, the service is 240 volt, single phase. thanks.
