Conductors in a cable tray are installed per 392.80(A)(2)(d) and both ends of the conductors emerge from the cable tray and terminate in equipment with 75C rating. Since the conductors are installed per 392.80(A)(2)(d), with proper spacing then, Table 310.15.(B)(20) can be applied, but when the conductors exit the cable tray to terminate in equipment Table 310.15(B)(16) shall be applied.
Can I use Table 310.15(B)(16) to determine the minimum size conductor with no adjustment factors then, apply all the correction factors for the same cable size to conductor ampacities in Table 310.15.(B)(20)?
