An electrical system includes an enclosure for housing an electrical device. The enclosure includes a door with an operating handle connected to a shaft when the door is closed, which can then be used to turn the electrical device on or off. The shaft rotation is further operable to simultaneously displace an interlock mechanism for engagement or disengagement to a busway structure.
