Abstract: 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.

Abstract: 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.

Abstract: 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.
