Low Voltage BuswayPow-R-Way III A Space-Saving Innovation— The Corner Joint Elbow The Pow-R-Way III corner joint combines the features of the Pow-R-Bridge with reduced elbow leg lengths. Due to its compact design, the corner joint allows for layouts that provide optimum use of space and increases available plug-in openings. Enhanced Bus Plug Design Facilitates Installation and Improves Safety Pow-R-Way III plug-in protective devices are available in circuit breaker and fusible switch designs. Standard features include: oversized enclosures, extended ground and neutral bars, line side...

Low Voltage BuswayPow-R-Way III General Information • Determine the total footage, all fittings and accessories for entire busway run. Price the total footage by type and system requirements. Round footage up to the nearest foot. Add the fabrication charge for the fittings. Add any additional accessories required for the total price of the busway run • See NEC 364.11 for Reducer Application • Fusible reducers are 600 V maximum; fuses are not included Transformer Connections • Transformer tap bus extensions do not include drilling or lugs • Transformer throats include flexible connectors...

Pow-R-Way III Traditional Indoor and Outdoor Elbows Elbows are used to make 90° changes in the direction of busway runs. The four types that are available are forward, rearward, upward and downward. Corner Joint Elbows The Pow-R-Way III corner joint elbow can be installed in areas where a traditional 90° turn could never have been accomplished before. Pow-R-Way III corner joint elbows can solve any serious pathway problem and contribute to successful layouts with minimal space requirements. The corner joint elbow is UL listed for indoor applications only and is also certified for...

Low Voltage BuswayPow-R-Way III Crosses A cross is a busway fitting suitable for connection in four directions. It is applied when a bus run must branch off in three directions, all in the same plane. End Cable Tap Box End cable tap boxes are used to feed a run of busway with cable and conduit or where loads served by busway are connected without the need for overcurrent protection. Center Cable Tap Box Center cable tap boxes are used to center feed a run of busway with cable and conduit or where loads served by the busway are connected without the need for overcurrent protection....
