Abstract
Interlock structure for a circuit breaker is constructed and arranged such that 1) when a control plug is disconnected from a socket, a portion of a linkage structure engages a racking linkage, causing a portion of the racking linkage to engage a racking screw, preventing the racking screw from rotating and thus preventing racking of the circuit breaker, and 2) when the control plug is connected with the socket, the linkage structure is actuated thereby moving the portion of the linkage structure to disengage from the racking linkage such that the portion of the racking linkage disengages from the racking screw, permitting the racking screw to rotate thereby permitting the circuit breaker to be racked to a connected position, where the primary contacts are connected to the main bus.
