Abstract
A circuit breaker racking system and method may include a movable A-frame operable to attach to and release a circuit breaker, and move it forward and rearward along two space-apart arms. Rails associated with each of the arms may be movable upward and downward to lift and release the circuit breaker from a floor or platform. A drive screw assembly on the circuit breaker racking system may be actuated to pull a circuit breaker forward out of a cabinet or to push the circuit breaker back into the cabinet by engaging with a screw mounted to a wall of the cabinet. The circuit breaker racking system may be manually operated and moved about a control room, or may be remotely moved and actuated by an operator outside of the control room.
