An electrical system includes an enclosure for housing an electrical device. The enclosure includes a door with an operating handle connected to a first shaft that turns the electrical device on or off when the door is closed. The operating handle is further operable to simultaneously rotate a cam assembly, which in turn rotates a second shaft which displaces an interlock mechanism for engagement or disengagement to a busway structure.

A power distribution system includes a busway and a bus plug. A mechanical assembly rotatably mounts the bus plug relative to the busway. The system includes a remote racking device including a mechanism having a first mechanical component coupled to the bus plug and a second mechanical component coupled to the busway. The remote racking device rotates the bus plug relative to the busway about a rotation axis defined by the mechanical assembly based on mechanical interaction of the first mechanical component and the second mechanical component. Methods of connecting and disconnecting a bus plug relative to a busway with a remote racking device are also provided.

Power inverter assemblies are provided herein for use with motor vehicles. An inverter assembly may have a symmetrical structure configured to convert DC input power to AC output power. The inverter assembly may include a housing enclosing a symmetrical DC input portion, a symmetrical AC output portion, a DC link capacitor, and a gate drive portion having a pair of power modules. The symmetrical DC input portion can include a DC input bus bar sub-assembly to which the DC link capacitor is coupled, and a second DC bus bar sub-assembly that may electrically couple the DC link capacitor with the power modules. The symmetrical AC output portion may include a three phase output AC bus bar sub-assembly to which the power modules can be electrically coupled. A cooling sub-assembly may be provided for cooling the power modules with fluid transfer using a coolant.
