Abstract: A multi-latch compatible system is disclosed for electrical enclosures. The system accommodates latches of different types and configurations. A rail structure may be formed to interface with pin-type latches and with plate-type latches. The rail structure may be configured as a pre-assembled insert that can be placed within an electrical enclosure. The system permits the same general structure to be used regardless of the type of latching mechanism selected and installed in the enclosure.

Abstract: A packaged electrical system includes an enclosure and a main interior volume for component supports. The component supports may support electrical, electronic, power electronic and similar components, as well as switchgear and the like. A main power wireway is provided adjacent to the main interior volume of the enclosure for accommodating three phase power conductors. A network and control power wireway is formed separately from the main power wireway. The network and control power wireway may be formed toward the rear of the main interior volume, and may accommodate plug-in connections between component supports and network conductors and control power conductors. The network and control power wireway is thus accessible through a separate door from the main power wireway.

Abstract: A bus support system is disclosed that accommodates three-wire three-phase circuitry and four-wire three-phase circuitry. A main bus support element is designed to receive horizontal bus bars and vertical bus bars for installation in an electrical enclosure. The main support element is supplemented by an add-on bus support element where a neutral bus is required for four-wire three-phase operation.

Abstract: A connector arrangement for packaged electrical systems, such as motor control centers includes a component connector assembly mounted to component supports for providing network signals and control power to components on the support. A mating prewired connector assembly in the enclosure is forced to mate with the component connector assembly when the component support is fully engaged within the enclosure. Thereafter, the component support may be partially withdrawn from the enclosure to disconnect main power from the component support, while leaving network connections and control power connections by virtue of the mated connectors. The connectors engage by non-sliding contact both when fully engaged and when the components are partially withdrawn from the enclosure.

Abstract: A reduced form factor component support is provided for motor control centers and similar packaged electrical systems. The reduced form factor component support may be used with smaller components, such as small motor starters, motor drives, and so forth. Electrical connections with standard bus bars in the enclosure are made through special connectors mounted on subplates in the rear of the enclosure, or by an invertible stab housing that can allow the reduced form factor component support to share conventional slots in a bus cover, thereby providing access to the supply power in the enclosure.
