Abstract: A terminal assembly may be provided which utilizes an electrically insulating cover to electrically isolate upper portions of screw terminals. The electrically insulating cover could be made from plastic, rubber or some other electrical insulator, and could be mounted on a frame configured to engage with a frame supporting the screw terminals. While lower portions of the screw terminals may continue to electrically connect with electrical connectors for receiving load stab conductors (from a unit), upper portions of the screw terminals may be electrically isolated to protect from short-circuit, and/or shock, such as while a door or access panel of a wire-way is removed. The electrically insulating covers may also include cable glands for circumferentially surrounding wires leading to the screw terminals. A retainer clip may also be used to securely hold the electrically insulating covers to the frame supporting the screw terminals.

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.
