Would anyone mind trying to explain this language in 310.15(B) to me? Specifically the part in bold below. Is it just trying to say the same thing as 110.14(C)? The way it is actually written would mean if your adjusted and corrected ampacity is still above your 75c ampacity then you can't use the 90c rating for adjustment and correction, which isn't what I believe they are trying to say. Also, wouldn't it make since to not have the language in this section since this is covered in 110.14(C) and in my opinion more clearly.
Thanks

The temperature correction and adjustment factors shall be permitted to be applied to the ampacity for the temperature rating of the conductor, if the corrected and adjusted ampacity does not exceed the ampacity for the temperature rating of the termination in accordance with the provisions of 110.14(C).
110.14(C)
Conductors with temperature ratings higher than specified for terminations shall be permitted to be used for ampacity adjustment, correction, or both.
