§2907. Overcurrent Protection.


Motors driving single or multiple d.c. generators supplying a system operating on a cyclic load basis do not require running overcurrent protection, provided that the thermal rating of the a.c. drive motor cannot be exceeded under any operating condition. However, the branch circuit protective device(s), which may be external to the motor, must provide short circuit and locked rotor protection.
