Abstract
A method of tripping a circuit interrupter in a back fed configuration is provided, wherein the circuit interrupter has separable contacts and an actuator, such as a solenoid, operatively coupled to the separable contacts. The method includes detecting within the circuit interrupter that a fault condition exists, and subsequent to detecting that the fault condition exists, determining whether a current is flowing within the circuit interrupter between a load side of the circuit interrupter and the separable contacts, and controlling operation of the actuator based on whether the current is flowing within the circuit interrupter.
