Abstract: A motor control center system is provided. The system includes an electrical enclosure having buses for routing electrical power to component units. The system also includes a component unit disposed in a compartment of the electrical enclosure. The component unit contains a component for managing a power supply to a load disposed outside of the enclosure. In addition, the system includes a ground element disposed along a support wall of the compartment, wherein the ground element provides a fused ground connection with a load terminal of the electrical enclosure when the component unit is withdrawn from the electrical enclosure.

Abstract: A stab for use in a plug-in assembly includes a stab piece and a lug. The stab piece includes one or more contact arms configured to engage a bus bar, and a base portion coupled to the one or more contact arms. The base portion is configured to be coupled to a stab shaft for rotating the stab about a rotational axis to transition the stab from a retracted position to an extended position. The lug is coupled to the stab piece and configured to receive wire for transmitting power from the bus bar to an electrical component. The lug is configured to be deformed around the wire to hold the wire when a crimping force is applied to the lug. The lug is configured to hold the wire at a position approximately centered on a rotational axis of the stab shaft when the lug is deformed by the crimping force.

Abstract: A system for adjusting the position of a circuit breaker is provided. The system allows for translation of the circuit breaker with respect to a support base and interfacing mechanisms, such as those that serve to switch the circuit breaker between its operative states. Adjustment is afforded by an adjustment plate fitted to the support base and that moves with the circuit breaker. Slots through the support base allow for movement of the plate and circuit breaker. A threaded member allows for continuous movement of the plate and circuit breaker for accurate positioning.

Abstract: An operating system for a circuit breaker includes a bail and a base that supports the circuit breaker and the bail. The bail extends around the circuit breaker and is pivotally attached to the base, such as by snap engagement. The bail and the base are made of an insulative plastic material such that the circuit breaker may vent hot gases, charged particles, plasma and the like without transferring charge to the operating system components. Additional features may be molded into the parts, such as supports and operators for auxiliary switches.

Abstract: A gas directing system for a circuit breaker is disclosed. The system includes an insulative housing that fits over vents that convey hot gases upon operation of the circuit breaker. The housing has phase partitions that separate phase sections from one another, and transverse partitions that separate a venting sections for each phase from terminal sections. Gas diverting structures are provided in the venting sections that redirect hot gases towards apertures through which the gases vent. The overall structure may be much lower profile than previous design spacing requirements.

Abstract: Present embodiments include a system and method for providing a bus bar boot or cover for a bus bar feature formed from a material with an integral or non-integral pest repellent. The bus bar boot or cover may include a polymer formed with geometric features configured for formfitting about a bus bar component. The pest repellent may be integrated with the polymer or applied to the polymer.
