"If you had a 60 degree wire, the result of using the 60 degree column would be a larger wire, not a smaller one." That would not be true for sizes 14,12 and 10. True for larger sizes.

"So I just happen to have a 20a breaker made by American Circuit Breaker Corporation and it plainly say "Use only in Listed enclosures" and "Use 75 degree conductors only" 120/240v."
George I believe you but I do not understand
the reason. Under the 60C and 75C col, #12 conductor is rated for 20 amps. If you use
the 60C conductor at 20 amps continuous load the temp will rise to 60C. Should be no problem for the breaker.
Actually the conductor is rated at 25 amps. The NEC limits the load to 20 amps.
