Abrégé

A system and apparatus for maintaining the desired synchronous and asynchronous A and B auxiliary electrical circuits, respectively, by use of connector block halves, one connector block half being connected to wiring out for auxiliary circuitry and being secured to the movable circuit breaker and the other auxiliary connector block half also being connecting to wiring out for auxiliary circuitry and secured to the relatively stationary wall or surface of the cubicle, where the connector block halves have some portion of its contacts of the “make before break” type so that the A and B auxiliary circuits operate as intended when the connector halves are connected and the A and B auxiliary circuits still reflect the proper condition, synchronous or asynchronous, of the A and B circuits, respectively, even when the auxiliary connector block halves are physically and/or electrically separated from one another.

Abrégé

A racked in and out circuit breaker for a cubical housing of electrical switchgear has a back to front, threaded rod mechanism and, at the rear of the cubical a stationary and interior threaded bolt is provided so that when the rod is turned the circuit breaker is mechanically pulled into the cubical and, if turned oppositely, causes the circuit breaker to move out of the cubical housing. A non-threaded section of the rod cooperates with the same bolt so that when it is within the threads of the bolt, further effort at rotating the rod prevents further rearward movement of the circuit breaker.
