Circuit Breaker Terminal Temperature rating: 60C or 75C conductor?

[jayzbond007]

Hello,

I am installing a solar load center with a 70A circuit that is running back to main service panel. If the terminal temperature rating of the circuit breakers on both ends (load center and Main panel) are 60/75C, does that mean that I can use either 60 or 75C rated conductors per table 301.15(B)(1)?

I understand that 110.14(C)(1)(a) talks about using the 60C column for circuits under 100A if the terminal rating is not listed, and 75C for circuits that are 100 or more.

Any help is greatly appreciated.

Thanks.
