Abstract: A portable motorized racking device and system are disclosed for remotely racking (inserting or removing) drawout circuit breakers. The racking device provides a portable, motorized device that can be hand carried to a work location and affixed to the circuit breaker without the need of any modification to the breaker or its enclosure. In one embodiment, among others, the torque that is required to operate the breaker racking mechanism is provided by an electrically powered gearmotor. Attached to the output shaft of the gearmotor is a socket that engages the circuit breaker racking screw. An anti-rotation plate engages a feature, such as a bolt head, opening, hole, or edge, on the racking screw support frame or the breaker face to prevent the gearmotor from rotating while the socket rotates the racking screw.

Abstract: A mounting device enables detachable mounting of equipment against a face of a motor control center (MCC) unit. The face of the MCC unit has a plurality of protruding ports and an operating switch extending outwardly from the face. The protruding ports are designed to enable installation and removal of the MCC unit from a housing. The operating switch is designed to enable switching of electrical power within the MCC unit. The mounting device has a plate or bracket, a mechanism for attaching and un-attaching the plate or bracket to at least one of the protruding ports, and screw holes or other features to enable mounting of equipment to enable the equipment to engage the protruding ports, the operating switch, or both.

Abstract: Disclosed are various embodiments for racking a draw-out circuit breaker. A portable motorized racking device may be connected or disconnected from an racking assembly of the circuit breaker. The portable racking device includes a gearmotor, a drive socket for engaging with the racking screw of the circuit breaker, and a locking disk for securing the portable racking device to the racking assembly of the circuit breaker. The gearmotor may be remotely controlled to rack the draw-out circuit breaker.

Abstract: A portable actuator system enables the remote operation of electrical disconnect switches with a portable actuator device that is temporarily installed at the disconnect switch location. An embodiment, among others, of the portable actuator device has an electric motor having a drive shaft that can be controlled to rotate about a longitudinal axis. The actuator device also has elongated movable first and second arms that are controlled by the drive shaft. The first arm engages and moves the disconnect handle in a first rotational direction so that the disconnect handle is switched to the open position. The second arm engages and moves the disconnect handle in a second rotational direction so that the disconnect handle is switched to the closed position.

Abstract: A portable actuator assembly for remotely operating the control components on a circuit breaker which self-aligns by engaging a recessed area of the circuit breaker. The portable actuator assembly is easily and accurately aligned with the control components on the circuit breaker by an alignment fixture that engages the recessed area of the circuit breaker. The alignment fixture is moveable along one axis that lies perpendicular to the face of the circuit breaker in order to compensate for variations between the plane of the face of the circuit breaker and the plane of the sheet metal enclosure surrounding the circuit breaker. The alignment fixture is forced toward the face of the breaker by spring action to ensure it remains in constant contact with the circuit breaker. Strong magnets may hold the portable actuator assembly against the circuit breaker by attaching to the sheet metal enclosure surrounding the circuit breaker.
