Bus mounted surge protection devices are provided that are configured to be positioned in a panelboard alongside one or more similarly sized circuit breaker devices. The bus mounted surge protection device is configured to be received by a same provisional bus as the one or more circuit breaker devices and the bus mounted surge protection device is configured to protect all of the one or more circuit breaker devices in the panelboard.

On embodiment of the disclosed invention provides an electrical equipment cubicle having at least one removable side panel. The removable side panel is not fixed to the electrical equipment cubicle. Instead, the removable side panel is removably coupled to the frame assembly by an easily separable coupling device such as, but not limited to, a tab-and-receptacle device and/or easily accessible fasteners.

A maintenance-free electrical bus assembly is provided for a switchgear cabinet. The maintenance-free electrical bus assembly is coupled to a switchgear device in the cabinet, and includes electrical bus members, at least one bus joint comprising an electrical connection of two or more electrical bus members, and a fastener assembly fastening the bus joint and maintaining the electrical connection between the electrical bus members thereof. The fastener assembly includes at least one first fastening element having a plurality of first threads, and at least one second fastening element having a plurality of second threads. The second threads threadably engage the first threads of a corresponding first fastening element, in order to perpetually secure the first threads and the corresponding first fastening element, and to resist undesirable loosening of the bus joint once the fastener assembly has been fastened. Thus, inaccessible bus joints within the cabinet do not need to be inspected.

A grounding device for a roll-out electrical component is provided. The grounding device includes an actuation assembly, a static grounding contact assembly, and a biasing device. The actuation assembly structured to be engaged/disengaged by a roll-out electrical component. The static grounding contact assembly has at least one static grounding contact member that is structured to move between a first position, wherein the static grounding contact member does not contact a roll-out electrical component at least one contact, and a second position, wherein the static grounding contact member contacts, and is in electrical communication with, the roll-out electrical component at least one contact. The static grounding contact assembly is coupled to the actuation assembly and responsive to the position of the roll-out electrical component. The biasing device is structured to bias the actuation assembly and the static grounding contact member to their respective first positions.

An electrical bus member mounting system is provided for an electrical enclosure including a housing having a front, a back and a plurality of sides, a plurality of sections disposed between the sides, at least one electrical apparatus disposed within a first one of the sections, and an electrical bus assembly electrically connected to the electrical apparatus. The electrical bus member mounting system includes a mounting assembly having a first portion and a second portion. A plurality of electrical bus members are coupled to the first portion and the second portion is coupled at or about at least one of the sides of the housing within a second one of the sections thereof. Accordingly, the electrical bus member mounting system consolidates a substantial portion of the electrical bus assembly at a single location within the second one of the sections of the housing, in order to facilitate access thereto.

A stop device for an electrical device cell includes a generally flat, rectangular stop member and a generally flat, elongated permissive member. The stop member is, preferably, part of a stop member assembly that includes a biasing device. The cell includes a pair of rails upon which a drawout electrical device is movably disposed. The stop member is disposed adjacent to at least one housing assembly rail and is structured to move between a first, extended position, wherein the stop member engages the drawout electrical device and prevents the drawout electrical device from moving from the first, installed position to the second, drawn out position, and a second, withdrawn position, wherein the stop member does not engage the drawout electrical device and the drawout electrical device may move from the first, installed position to the second, drawn out position.

The movable conductors of a three phase isolation switch are incorporated into the electrically insulative molded shaft, thereby mechanically supporting them and isolating them from the metal axle of the shaft. Movable contacts on the ends of each movable conductor are angularly spaced by &#x3b1; degrees, where &#x3b1; is less than 180&#xb0; and is 90&#xb0; in the exemplary embodiment. A common fixed load contact is located angularly between, and spaced &#x3b1; degrees from, both the fixed line and ground contacts so that the shaft is rotated only &#x3b1; degrees between a first, closed position, in which the movable conductors connect the fixed load contact for each phase to the corresponding fixed line contact, and a second, grounded position, where the fixed load contact of each phase is connected by the movable conductor to the corresponding fixed ground contact.

An improved frame for a switchgear cabinet includes a plurality of rails that are connected together with a plurality of connectors. The rails are generally of two different cross-sectional configurations, both of which are cooperable with a single type of connector to enable the rails and connectors to be configured into numerous different types of cabinet frames to which panels can be mounted to form switchgear cabinets. The rails and connectors are modular in nature and are specifically configured to be easily connected with one another. During assembly of the connectors and the rails, portions of a coating on the rails become ruptured, thereby electrically conductively connecting together the rails and the connectors.

An electrical busway plug-in brick for mounting on a busway housing includes openings which allow access to bus bars running along the length of the housing. Barrier members are preferably positioned across the openings to restrict access of fingers or other similarly sized objects through the openings, while allowing electrical contacts to be made therethrough. The plug-in brick preferably includes a lockable cover which deters unauthorized access to the openings of the plug-in brick. The openings may extend unequal distances through the plug-in brick in order to provide increased creep and strike distance which prevents electrical arcing. The plug-in brick may be mounted on the busway housing by release pockets which prevent destruction of the plug-in brick upon a short circuit by allowing the plug-in brick to be detached from the housing.

Busway plug in brick and cover

A busway system having several parallel bus bars arranged in a housing with a plug-in opening in a front wall of the housing employs a cover assembly with a plug-in unit over the plug-in opening. The cover assembly has a brick mounted onto the front wall of the housing, and a shutter attached to the brick. The brick has a plurality of cavities each of which receive a stab of one of the bus bars, and has a guide opening along its bottom wall on opposed ends. The shutter extends across the front of the brick, is positionable over the several cavities of the brick, and has a configuration corresponding to the arrangement of the cavities. A cam-linkage assembly located on opposed sidewalls of the brick is spring biased and allows the shutter to be moved along tracks of the brick for opening and closing the cavities. The plug-in unit has guide probes which enter the guide openings along the bottom of the brick as the plug-in unit is being installed onto the busway system. The guide probes contact cams of the cam-linkage assemblies, causing the cams to rotate to move the links and, therefore, the shutter in an open positioning for the cavities. Removal of the plug-in unit from the busway system removes the guide probes from the guide openings of the brick, thereby allowing the springs to move the shutter to its previous positioning to close the cavities in the brick.
