A molded case, cassette type circuit breaker for a multi-pole electrical distribution circuit includes a number of cassettes equal to the number of poles in the multi-pole electrical distribution circuit and a pin disposed through each cassette. The rack is preferably one piece and uses the depth out away from the wall to hold multiple items. The rotation is controlled by the controller. The lower surface is capable of being removably affixed to a floor. When the difference is greater than or equal to the vibration determination threshold, the antiskid control system determines that a driveline vibration is generated and executes a control for converging the driveline vibration.
