Answer:
Hello Tim, the stairwell is most likely a fire-rated egress enclosure stairwell. Section 300.25 limits electrical wiring serving equipment in the stairwell enclosure and permitted by the AHJ. The a general feeder as described in the question is not serving the stairwell enclosure, as such it would not be permitted.
