摘要： An interlock system for a switchgear cabinet of a drawout switchgear device includes a guide rail in the cabinet to align rollers supporting the drawout switchgear device. A stop plate is spring biased toward a blocking position to block the rollers from rolling off the guide rail. A deflector surface on the stop plate receives a contact force from a fastener hook of a lift truck, to move the stop plate and unblock the rollers. The fastener hook then anchors the lift truck to the cabinet after the stop plate has moved away from the blocking position. A bridging guide rail mounted on the lift truck, aligns with and abuts the guide rail in the cabinet to allow the drawout switchgear device to be safely rolled into or withdrawn from the cabinet by an unassisted service person operating the lift truck.

摘要： A racking assembly for an electrical apparatus is provided. The racking assembly includes a movable carriage assembly and a drive assembly. The movable carriage assembly is sized to fit within a housing assembly and is structured to be moved between a first position and a second position. The carriage assembly is further structured to support at least one electrical component. The drive assembly includes a motor assembly and a positioning assembly. The motor assembly is structured to impart movement to said positioning assembly. The motor assembly is coupled to said positioning assembly. The positioning assembly is structured to impart movement to said carriage assembly and to move said carriage assembly from said first position to said second position. The positioning assembly is coupled to said carriage assembly. In this configuration, the racking assembly is structured to move the carriage assembly, and therefore the electrical apparatus, between the first and second positions.

摘要： A system and method for connecting supply power to motor control components includes use of a motor control center subunit with moveable supply power contacts. After a motor control center subunit is secured into a motor control center compartment, the supply power contacts may be advanced to engage supply power buses. For disconnection, the supply power contacts may be retracted and isolated from the buses before physical removal of the subunit.

摘要： The present inventors have recognized that electrical units for Motor Control Centers (MCC's) can be improved to allow testing in a partially disconnected state while providing ingress protection through the use of sealing members without decreasing the size of the electrical unit. In particular, a full size electrical unit, able to advantageously accommodate a full array of electrical components like most other electrical units, can be partially withdrawn from an MCC for testing while still providing protection from the possibility of shock, gases and/or other hazards by way of sealing members such as gaskets and/or plates. Such sealing members can be mounted to the electrical unit to effectively seal the electrical unit with respect to the MCC when partially withdrawn.
