[RE-wrenches] Three Inverters, One Disconnect?

[Garrison Riegel]

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.

 

Garrison
