1. An electrical switching apparatus including an interrupting rating, said electrical switching apparatus comprising:

  • a number of separable contacts;

    an operating mechanism structured to open and close said separable contacts;

    a number of sensors structured to sense at least current flowing through said separable contacts; and

    a processor structured to cooperate with said operating mechanism to open and close said separable contacts, and to determine a fault from said sensed current flowing through said separable contacts,wherein said processor is further structured to responsively open said separable contacts if the sensed current associated with said fault is less than said interrupting rating, andwherein said processor is further structured to keep said separable contacts closed and wait for another circuit interrupter to interrupt said fault if the sensed current associated with said fault is greater than said interrupting rating.
