Where separate overload devices
are used with a standard part-winding start induction motor, each half of the motor winding shall be individually protected in accordance with 430.32
with a trip current one-half that specified.
Each motor-winding connection shall have branch-circuit short-circuit and ground-fault protection rated at not more than one-half that specified by 430.52.
Exception: A short-circuit and ground-fault protective device shall be permitted for both windings if the device will allow the motor to start. Where time-delay (dual-element) fuses are used, they shall be permitted to have a rating not exceeding 150 percent of the motor full-load current.
