Had an interesting question come to me today. We found another solution to avoid a pass through but would like to know all the info about doing the following:

Large residential single family job..200 amp sub panel in basement that feeds a 100 amp panel in completely separate workshop room in basement and a 40 amp lighting panel also in the workshop. Desire is to make the 100 amp in workshop a shunt trip panel, but there is one circuit for a general purpose outlet in the shunt trip panel. We want to maintain power to this outlet even when shunt trip activates. our initial plan was to use shunt panel as a pass-through and pull general purpose outlet circuit to the 200 amp sub panel and feed from there.

I have read 330.3(c) The way I read it we are allowed to do that. is there a code article indicating another wire color to identify foreign circuit? and what code stated the requirement for labeling..power from other sources..

thanks for the info.

I think you meant 300.3(C), and no there is no other code section for labeling a branch circuit that junctions in a panel that it does not originate in, I would tag it or get your hands on a decent label maker.
