Bill,
The diagram that Steve suggested in the 2007 Patriot Thunder Wiring Diagram is identical to the AC wiring diagram in the 2006 hard copy set that came with our coach. In fact, with few exceptions most of the 2007 Patriot Thunder Wiring Diagram is the same as my 2006 hard copy set.
If you look at the AC breaker panels (above the toilet for our floorplan), the panel on the right with the 50-amp dual breaker is the main AC panel. Nothing in this panel is powered by the invertor. The sub-panel on the left is the invertor panel and everything in this panel is powered by the invertor.
On our coach, the only interior AC receptacle that I have discovered that is not powered by the invertor is the washer/dryer. According to the diagram, if you have the optional Insta-hot and/or dishwasher, they are also not powered by the invertor.
