Physical data (continued)
Traditional indoor and outdoor elbows (Figure 17)
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. See minimum leg lengths listed for each type in
Table 19 and Table 20.
ote:N All dimensions are to the centerline of the Pow-R-Bridge.
Figure 17. Traditional elbows
Corner joint elbows (Figure 18)
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 seismic withstand
capability to worst-case, Zone 4 levels.
ote:N All dimensions are to the centerline of the corner joint connection.
