Abstract: An adjustable wireway assembly for use in an electrical enclosure includes a panel structured to form a portion of the electrical enclosure, the panel having a first aperture defined therein. The assembly further includes a plate member selectively coupled to the panel about a portion of the first aperture in at least one of a first position and a second position in a manner that blocks at least a portion of the first aperture and thereby defines a second aperture formed from a portion of the first aperture. When coupled in the first position, the second aperture is of a first area and when coupled in the second position, the second aperture is of a second area different than the first area.

Abstract: An arc management system for an electrical enclosure assembly is provided. The electrical enclosure assembly includes a housing assembly and a conductive bus assembly. The arc management system includes a number of conductive bus extension assemblies, a number of first and second arc horn assemblies, and a number of ground conductor assemblies. Each conductive bus extension assembly includes a conductive member coupled to the conductive bus assembly. Each first arc horn assembly includes a conductive arc horn member. Each first arc horn member is in electrical communication with an associated bus extension conductive member. Each second arc horn assembly includes a conductive arc horn member. Each ground conductor assembly includes a ground conductive member. Each second arc horn member in electrical communication with an associated ground conductor assembly ground conductive member. Each first arc horn member is associated with a second arc horn member and disposed an effective distance therefrom.

Abstract: An improved conduit apparatus in accordance with the disclosed and claimed concept includes one or more conduits that each enclose therein an electrical conductor that carries a phase of a multi-phase electrical supply. The conduits are connected to the walls of the electrical enclosures with an attachment apparatus that extends between the conduits and the walls of the electrical enclosures. A clamp apparatus retains the electrical conductors in a state of tension within an interior region of the conduits in a position spaced from the walls of the conduits.

Abstract: An inter-pole drive bar in accordance with the disclosed and claimed concept is usable to extend among a plurality of poles of an improved switch apparatus and to cause the plurality of poles to be together moved between a CLOSED position and an OPEN position. The inter-pole drive bar is elongated and has a plurality of connection points that are connectable with the poles and further includes a number of features that avoid engagement or other interference between the inter-pole drive bar and the various structures of the switch apparatus. The inter-pole drive bar includes an elongated linkage element whose movement between the CLOSED and OPEN positions of the switch apparatus are primarily translation of the linkage element in a direction generally parallel with its longitudinal extent and translation of the linkage element in a direction generally perpendicular to its longitudinal extent.
