Have a small 550va inverter being installed in an area that has handful of office 2x4 fixtures being fed from output/source side of the inverter to provide egress illumination. I under stand per Art 700 input and output/source circuits need to be separate (including keeping only EM source circuiting in raceways that house these circuits), but what about the branch circuit feeding the inverter? Can that be ran in a conduit with other standard branch circuits? Or does the feeder circuit to the inverter need to be treated the same. The inverter is calling out it’s own dedicated circuit. I’m getting conflicted info from reading over 700.17 (2).

First I would like to offer kudos that you looked in the code first. What Ron said, but

700.17 starts out branch circuits that supply emergency lighting. An emergency inverter is a separately derived system,([edit] when in battery mode) so the branch circuit feeding it isn't the same branch circuit as the one feeding the emergency lighting. The emergency lighting branch circuit starts at the inverter and ends at the emergency lights. 700.17(2) isn't applicable to this installation unless the lights are switched AFTER the inverter. When you have power feeding an inverter and the inverter feeding lights that are powered 24/7 (or switched at the inverter) the wiring on the load side shall be compliant with 700.17(1). not 2
