Abstract: A surge clamp for use on sectionalized electrical busway distribution system housings. The surge clamp is cut to length from an extruded rawstock. The extruded rawstock is provided with at least one generally flat longitudinal surface for engaging a generally flat surface of the busway housing duct top and duct bottom. The extruded rawstock also defines a passage extending along its longitudinal axis. The passage receives a fastening device such a screw at each end for attaching the surge clamp to the busway housing.

Abstract: A method of making a surge protection system for use on sectionalized electrical busway distribution system housings. The surge protection system includes a number of surge clamps; each cut to a particular length from an extruded rawstock. The extruded rawstock is of a length easily manipulated by one person. The extruded rawstock defines at least one generally flat longitudinal surface and a passage extending along its longitudinal axis. When each surge clamp is installed the generally flat longitudinal surface engages a generally flat surface of a top or bottom of the busway housing. Each end of the surge clamp engages one of two generally parallel sides of the busway housing. Apertures are defined in the sides at the point of engagement with the surge clamp ends. Fastening devices such a screw pass through the apertures and into the passage defined by the surge clamps thus providing a means for attaching the surge clamp to the busway housing.

Abstract: An elbow for changing the run direction of a pre-bussed rigid conduit electrical distribution system. The elbow has a number of individually insulated electrical conductors each of which is formed to a predetermined angle. The conductors are enclosed within a hollow housing which is formed to the same predetermined angle such that it will enclose the electrical conductors. A uniform and continuous support is provided for that portion of each electrical conductor which is enclosed within the housing.

Abstract: An device for changing the run direction of a pre-bussed rigid conduit electrical distribution system. The device has a number of electrical conductor assemblies which are substantially enclosed within a hollow housing. The housing has three legs which are integrally joined at a common point. Each leg has an associated end from which an equal length of each electrical conductor assembly extends. A uniform and continuous support is provided for that portion of each electrical conductor assembly which is enclosed within the housing.
