Hello I have a 350 amp service rack one panel on the left 200 amp one panel on the right 150 amp with the meter in the center. I have two separate conduit/feeders going to the structure . At the structure I have 150 amp main breaker 20 space exterior panel and a 200 amp exterior main breaker 20 space Exterior panel. In those panels I have the 220 circuits in there . Is everything to code? Because I believe the new 2020 NEC code allows multiple feeders going to the structure .
