An electrician is routing emergency feeder conductors for a high-rise building's exit lighting and fire pump system. The normal power feeders run through a common shaft. Per NEC, how must the emergency feeders be installed relative to the normal power feeders?
They can be installed in the same raceway if separated by a barrier.
They must be installed in a separate raceway, shaft, or trench from all other wiring.
They can be installed in the same raceway as the normal power feeders if rated for the highest voltage present.
They must be installed in a separate raceway, but can share the same shaft as normal power feeders.
