430.53 (A) will not help you here because both of your motors are over 1 horsepower. And 430.53 (A)(1) specifically does not allow motors over 6 amps.

1 HP = 746 watts

6.7 amps x 120 volts of alternating current = 804 watts
8.7 amps x 120 volts of alternating current = 1044 watts

Hope that helps you.
