Application: An industrial control panel has a 400 amp fused main disconnect. A set of #10 tap conductors leave the enclosure through a cable (not in a raceway) and go less than 10 feet to the top of a 30 amp fused disconnect which supplies power to a constant voltage transformer. There is no OCPD at the point where the taps originate (other than the 400 amp fuses in the main disco). I say that 240.21 (B) (1) (3) would require these tap feeders to be enclosed in a raceway (like conduit; not open cable or cable in a tray). If I am right, then am I also right in that if they were in a conduit that this application would satisfy 240.21?
