Cable bus conductor ampacity

[mash1234]

Cable bus is normally engineered based on NEC 370. The ampacity of the conductors are normally sized by manufacturers based on 310.15.(B).17, free air rating. For low voltage cable bus applications, will the cable bus conductor ampacity needs to meet the terminals 75C temperature rating per NEC 110.14.C.

You will to transition from the cable bus to your breaker with conductor ampacity based on 75 degree.

Thanks for the reply, will the cable ampacity be based on 310.15.(B).16 or (B).17.

Thanks for the reply, will the cable ampacity be based on 310.15.(B).16 or (B).17.

Because of NEC 110.14.C, I use Table 310.15(B)16 from manufacturer's documentation. Top of page 6 of the link below brings it home for me
