Abstract

An adjustable length busway joint for coupling a first and a second busway section, the first and second busway sections being longitudinally offset, is disclosed. The busway joint includes a first plurality of splice plates and a second plurality of splice plates disposed to overlap to form an electrical joint. The first and said second pluralities of splice plates are arranged for a longitudinal movement with respect each other between a first compressed position and a second extended position. The busway joint further includes a third plurality of splice plates. Each splice plate of the second plurality of splice plates overlaps a portion of a corresponding splice plate of the third plurality of splice plates to form an electrical joint. The third and second pluralities of splice plates are arranged for a longitudinal movement with respect each other between a third compressed position and a fourth extended position.
