Abstract
The outer surfaces of adjoining electrical busway side frames are shaped to define a protruding rail extending along the vertical axis thereof. A pair of recessed channels formed within the inner surfaces of the side frames of an intervening busway joint receive the busway rails at opposing ends thereof. Clearance arranged within the respective busway joint channels allows lateral movement of the busway side frames relative to the busway joint. Slots are provided on the busway joint side frames for visual indication of the position of the busway rails.
Claims30
An electric busway joint comprising:
- a plurality of apertured metal splice plates and a plurality of apertured insulating non-metallic plates arranged within a pair of metallic side frames, said side frames each including a first channel therein and defining a first recess within an interior surface thereof;
- a first electric busway section adjacent one end of said metallic side frames;
- said splice plates being arranged for receiving bus bar conductors extending from a first end of said first adjacent electric busway section, said first adjacent electric busway section including a pair of first opposing side frames each of which includes first rails extending from an exterior surface thereof;
- whereby said first channels capture said first rails to allow relative motion between said first electric busway sections and said metallic side frames.
An electric busway joint comprising:
- a plurality of apertured metal splice plates and a plurality of apertured insulating non-metallic plates arranged within a pair of metallic side frames, said side frames each including a first slot extending through a first end thereof;
- a first electric busway section adjacent one end of said metallic side frames;
- said splice plates being arranged for receiving bus bar conductors extending from said first adjacent electric busway section at a first end thereof, said first adjacent electric busway section including a pair of first opposing side frames each of which includes first tabs extending from an exterior surface thereof;
- whereby said first slots capture said first tabs to allow relative motion between said first electric busway sections and said metallic side frames.
