ABSTRACT:
Disclosed is a racking mechanism for a drawout circuit breaker including a cross shaft movably positioned in an enclosure and at least one input link in operable communication with the cross shaft via at least one connecting link. At least one racking cam is movably positioned in the enclosure and is in operable communication with the input link. Each racking cam has at least one cam slot receptive of a portion of the circuit breaker. Movement of the cross shaft about an axis of the cross shaft is capable of moving the at least one racking cam from an open position toward a closed position with the portion of the circuit breaker disposed in the at least one cam slot, thereby securing the circuit breaker in the enclosure and the at least one racking cam is in the closed position. A method for securing a circuit breaker in an enclosure and a circuit breaker assembly are also disclosed.
