not nessicarily true. You can gear the motors to match their performance curves, and in some situations (low torque, High speed) it may be better to gear them to have a max torque at 30 amps. There are no rules against using smaller breakers, because the only side effect for a mistake is a tripped breaker. If I recall correctly in years past pre-2004 there were no 40 amp breakers, cims were run on 30's and didn't have a problem.
