Adjustable electrical busway joint

An adjustable busway joint for coupling two longitudinally aligned busway sections is disclosed. The adjustable joint has a first plurality of electrically conductive splice plates defining a splice plate adjustment slot, and a second plurality of electrically conductive splice plates defining an aperture, wherein each splice plate of the second plurality of splice plates is disposed to overlap a portion of a corresponding splice plate of the first plurality of splice plates to form an electrical joint, and wherein the aperture is sized and disposed to overlap at least a portion of the first splice plate adjustment slot. The joint additionally has a first clamping member disposed through the splice plate adjustment slot and the aperture such that the first and said second pluralities of splice plates are operably movable with respect to each other between a first compressed position and a second extended position.
