Abstract: A jumper assembly that includes a plurality of modules structured to be coupled together in a nesting configuration. Each module has a housing assembly, a bus assembly, and a coupling means. The modules may include a three separate bus assemblies. Thus, the modular jumper assembly may be coupled to a three phase circuit breaker.

Abstract: A knockout access assembly on a cover assembly for a jumper assembly. The cover assembly has a planar member. The jumper assembly has one or more bus assemblies, each the bus assembly having one or more collar assemblies, and each the collar assembly having a top surface with a fastening device on the top surface. The jumper assembly further has a housing assembly, the knockout access assembly includes a portion of the cover assembly planar member having an opening, a removable member, and frangible tabs. The removable member is disposed within the cover assembly planar member opening. The removable member is coupled to the cover assembly planar member by one or more of the frangible tabs.

Abstract: A jumper assembly that includes a housing assembly and at least two bus assemblies. The housing assembly has a planar member and a plurality of upper and lower side walls extending generally perpendicular from opposite sides of the planar member. The housing assembly planar member has an upper side and a lower side with one or more openings passing therethrough. The at least two or more bus assemblies each have a planar bus member and one or more collar assemblies coupled to each planar bus members. The upper side walls form two or more separate upper raceways. The lower side walls form two or more lower raceways. The bus planar members are disposed in the lower raceways. The collars disposed in the upper raceways and coupled to the bus planar members through the housing assembly planar member openings.

Abstract: A removable quick connect terminal for an electric power switch has a molded housing with an open cavity and an electrically conductive terminal member with a plurality of male terminations that project through slots in a cavity wall in the housing into the open cavity. The terminal member has a tang projecting outward from the housing that is clamped by a conventional collar terminal to a power conductor of the switch projecting into an external terminal recess in the molded switch casing. The terminal member is secured to the molded housing by a pair of oppositely facing chamfered catches engaging an opening in the flat center section of the terminal member. The molded housing of the quick connect terminal has hooks which engage abutment surfaces on the switch casing and a pair of integral compliant latches which engage latch ledges in the external terminal recess to removably secure the housing to the switch casing.

Abstract: A monolithic finger barrier for blocking insertion of a human finger into the open end of a terminal recess in the molded casing of an electric power switch such as a circuit breaker includes a planar member that slides into mountings slots in the switch casing traverse to the open end of the terminal recess and has integral resilient fingers extending along one face adjacent side edges of the planar member. Laterally, outwardly extending catches on the resilient fingers, which engage catch surfaces in the casing, can only be released to remove the barrier when the planar member is installed with the one face facing away from the terminal recess so that integral grips on the fingers are accessible.

Abstract: A jumper assembly that includes a housing assembly and a plurality of bus assemblies. Each bus assembly has a planar member and one or more collar assemblies. The housing assembly has a plurality of upper raceways and one or more raceways provide access to each bus assembly collar. The raceways associated with different bus assemblies are separate from each other. The upper raceways having openings on the left and right sides of the housing assembly. The housing assembly has a connector structure on at least one of the left and right sides. The connector structure may be coupled to another jumper assembly.

Abstract: A miniature circuit breaker incorporating ground fault protection and arc fault protection has a common rocker button for selectively actuating a ground fault test switch and an arc fault test switch. A leaf spring seated in a groove in the rocker button has converging legs which bias the common rocker button from the ground fault test position, and in the opposite direction from the arc fault test position, respectively, toward a central, neutral position.

Abstract: A miniature circuit breaker providing arc fault protection and ground fault protection has a common rocker button that selectively deflects orthogonally oriented flat electrically conductive test switch spring contacts of an arc fault test circuit and a ground fault test circuit into engagement with a common contact to test each of these protection functions independently. The pivot axis of the rocker button is parallel to the planes of each of the test switch spring contacts and the button has opposed fingers which preload both of the spring contacts to bias the rocker button to a neutral position.

Abstract: A terminal connector connects wire with a range of diameters to the conductor of an electrical power switch. The connector includes a collar with a laterally extending slot sized and shaped to receive the switch conductor. An aperture adjacent the slot is sized to accommodate the full range of wire diameters. A screw is threaded into a longitudinal tapped bore in the collar to clamp the wire to the conductor. The collar is reversible on the conductor for access to the screw for panel and DIN rail mounting of the power switch. A telescoping screw extends the range of wire sizes accommodated. The aperture is shaped to funnel wire diameters in the lower end of the range of diameters under an inner screw of the telescoping screw and into engagement with the switch conductor.
