I agree with Bob, You need to perform a load calculation to determine the feeder conductor size. FWIW 210.20 (A) requires the breaker to be sized at 125% of the continuous load in addition to the feeder conductors, so if you actually have 100 amps of continuous load you would be required to have a 125 amp breaker.
