Cable ampacity in raceway leaving a cable tray
Cable ampacity in raceway leaving a cable tray
(OP)
If I use 392.80 to determine the ampacity of the conductors in a cable tray, how do I rate the ampacity if the conductors leave the tray in a raceway for approximately 6' and terminate at a switchboard? Do I need to follow 310.15 for raceway? Is there a maximum distance I can run them in raceway before changing the overall rating?

Check your code under Conductor Ampacity.
