A busway joint for coupling a first and a second busway section, the first and second busway sections (111,112) each having a plurality of bus bars (116A-116C, 126A-126C) and being longitudinally aligned, the busway joint comprising: a first plurality of electrically conductive splice plates (146A-146C) disposed in spaced apart substantially parallel relationship, each splice plate of said first plurality of splice plates defining a first splice plate first retaining portion; a second plurality of electrically conductive splice plates (136A-136C) disposed in spaced apart substantially parallel relationship, each splice plate of said second plurality of splice plates defining a splice plate first adjustment portion substantially longitudinally aligned with said first plurality of splice plates; a first end of each of the first plurality of splice plates (146A-146C) interleaving with a corresponding one of the bus bars (116A-116C) of the first busway section to form a corresponding electrically coupled fixed joint, a second end of each of the first plurality of splice plates (146A-146C) interleaving with a first end of a corresponding one of the second plurality of splice plates (136A-136C) to form a corresponding electrically coupled slidable joint and a second end of each of the second plurality of splice plates (136A-136C) arranged to interleave with a corresponding one of the bus bars (126A-126C) of the second busway section to form a corresponding electrically coupled fixed joint; and at least one first positioning member sized and configured to be operably disposed in said first splice plate first retaining portion and said second splice plate first adjustment portion; said first and said second pluralities of splice plates (146A-146C, 136A-136C) being arranged for a longitudinal movement with respect each other between a first compressed position and a second extended position. a first plurality of electrically conductive splice plates (146A-146C) disposed in spaced apart substantially parallel relationship, each splice plate of said first plurality of splice plates defining a first splice plate first retaining portion; a second plurality of electrically conductive splice plates (136A-136C) disposed in spaced apart substantially parallel relationship, each splice plate of said second plurality of splice plates defining a splice plate first adjustment portion substantially longitudinally aligned with said first plurality of splice plates; a first end of each of the first plurality of splice plates (146A-146C) interleaving with a corresponding one of the bus bars (116A-116C) of the first busway section to form a corresponding electrically coupled fixed joint, a second end of each of the first plurality of splice plates (146A-146C) interleaving with a first end of a corresponding one of the second plurality of splice plates (136A-136C) to form a corresponding electrically coupled slidable joint and a second end of each of the second plurality of splice plates (136A-136C) arranged to interleave with a corresponding one of the bus bars (126A-126C) of the second busway section to form a corresponding electrically coupled fixed joint; and at least one first positioning member sized and configured to be operably disposed in said first splice plate first retaining portion and said second splice plate first adjustment portion; said first and said second pluralities of splice plates (146A-146C, 136A-136C) being arranged for a longitudinal movement with respect each other between a first compressed position and a second extended position.
