Fittings—Elbows, Tees, and OffsetsSpectra Series™ LowAmp busway has acomplete family of standard catalog fittingsto meet virtually all layout requirementsusing the compact minimum sizes shown.Nomenclature for completely defining theturn is accomplished by looking into thejoint end with phase 0 side facing down onthe busway. Using this guideline, a rightelbow turns right, an up elbow turns up, etc.Every piece of busway is labeled to maintainproper phasing. Unless otherwise noted, allturn dimensions are defined from thecenterline of the joint end to the centerlineof the busway. Figures show dimensionsfor elbow, tee, and offset fittings.
