400a ATS for 2 200a panels

[gooblanzee]

My own personal house has essentially the METER feeding a 400 disconnect and then a Generac HTS (400A ATS). My "main" panel is a 400A subpanel. This feeds a couple of branch circuits and four other subpanels. My house is over 10,000 sf and has 8 panels.

This may be a crap shoot, but can you get me a part number for your 400a Main panel? and for the subsequent breakers feeding the subpanels?
If you look at my last post, you will see that I am in a similar situation as OP.

Typically 400A panels are full panelboards with bolt on breakers. I.E. for Siemens it would be a P1A...... for split phase. I believe Siemens does show some 400A load centers in their catalog. Not as familiar with other brands.
