Hello Wrenches,
On an upcoming project we are interconnecting (3) Power-One, ahem, ABB PVI 3.6 inverters to a 3Ph 277/480V service. Each inverter output is 16A at 277V, 1Ph. Is it code compliant to run the single phase output of each inverter to a single pole of a 3-pole [utility required] AC disconnect before landing at each 1-pole 20A breaker in the main panel? It would be great to avoid an inverter subpanel and 3-pole breaker in the MDP if possible. Thanks for your thoughts.
