Abstract
A power busway distribution section length which may be adjusted before, during, or after installation to better facilitate proper busway location and reduce installation and modification costs. The section length comprises two busway stubs which slide independently between a center busway splice-plate joint. Overlapping sheet metal enclosures are used to provide protection from inadvertent contact with live bus bars and allow the busway section length to be adjusted to a discrete length.
Claims8
An adjustable length bus section comprising:
- a center housing section and first and second side housing sections respectively in axial alignment with, telescoping over and slidably connected to said center housing section;
- first and second sets of electrically insulated bus bar conductors disposed within said first and second side housing sections, respectively, said first and second sets of bus bar conductors being at a 180 degree opposing angle with respect to one another, said first and second sets of bus bar conductors having overlapping slidable contact portions;
- clamping means for connecting the contact portions of said bus bar conductors and exerting clamping pressure on said contact portions to urge them in firm electrical contact engagement;
- means for joining said first and second sets of bus bar conductors to said first and second side housing sections, respectively, allowing said bus bar conductors to move along with said first and second side housing sections while said first and second side housing sections are slidably moved;
- and
- connecting means for connecting said center housing section to said first and second side housing sections, said connecting means being in axial alignment allowing said first and second side housing sections to slidably move along said center housing section in longitudinal movement.
