  • MCC closed door operation (CDO) push button interlock mechanism
    Patent number: 10672567
    Abstract: A closed door operation racking device is provided for racking a circuit breaker to and from a power bus from outside of a housing of a motor control center unit. The racking device includes a racking operator assembly and a push-button interlock assembly. The racking operator is configured to rack-in the electrical device and connect the stabs to a power bus in a connected position and to rack-out the electrical device and disconnect the stabs from the power bus in a disconnected position. The push-button interlock assembly prevents the operation of the racking operator under certain conditions, and includes a spring-loaded locker assembly and a spring-loaded push-button operator assembly. A push-button operator of the push-button operator assembly is depressed to disengage the locker assembly from the racking operator to allow operation of the racking operator.
