Abstract
A circuit breaker for an electric load includes first and second terminals; a number of first separable contacts each electrically connected between one of the first terminals and one of the second terminals; a first mechanism to open, close or trip open the first contacts; a number of second separable contacts each electrically connected in series with a corresponding one of the first contacts; a second mechanism to open or close the second contacts; a processor to cause the second mechanism to open or close the second contacts, annunciate through one of the second terminals a power circuit electrical parameter for the electric load, receive from a number of the second terminals a confirmation from or on behalf of the electric load to cause the second mechanism to close the second contacts, and determine a fault state operatively associated with current flowing through the second contacts.
