Adjustable electrical busway joint

1. A busway system, comprising:

a first electrical busway section;

a second electrical busway section, said first and said second busway sections being configured to be electrically coupled and disposed longitudinally offset from each other;

a busway joint disposed between and operative to couple said first and said second electrical busway sections, the busway joint comprising

a first plurality of electrically conductive splice plates 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 disposed in spaced apart substantially parallel relationship, each splice plate of said second plurality of splice plates disposed to overlap a portion of a corresponding splice plate of said first plurality of splice plates to form an electrical joint, 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 and operably disposed to overlap a portion of a corresponding said first splice plate first retaining portion;

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 being arranged for a longitudinal movement with respect each other between a first compressed position and a second extended position.

2. The busway system of claim 1 wherein said busway joint further comprises:

at least one first clamping member;

each splice plate of said first plurality of splice plates further defines a first splice plate second retaining portion; and

said at least one first clamping member is configured to be operably disposed in said first splice plate second retaining portion.

3. The busway system of claim 1 , wherein said busway joint further comprises:

at least one second clamping member;

each said splice plate of the second plurality of splice plates further defines a second splice plate second retaining portion; and

said at least one second clamping member is configured to be operably disposed in said second splice plate second retaining portion.

4. The busway system of claim 1 , wherein said busway joint further comprises:

a third plurality of electrically conductive splice plates, disposed in spaced apart substantially parallel relationship, each splice plate of the said third plurality of splice plates defining a third splice plate first retaining portion;

each said splice plate of said second plurality of electrically conductive splice plates further disposed to overlap a portion of a corresponding splice plate of said third plurality of splice plates to form an electrical joint, each splice plate of said second plurality of splice plates defining a splice plate second adjustment portion substantially longitudinally aligned with said third plurality of splice plates and operably disposed to overlap a portion of a corresponding said third splice plate first retaining portion; and

at least one second positioning member configured to be operably disposed in said splice plate second adjustment portion and said third splice plate first retaining portion;

said third and said second pluralities of splice plates being arranged for a longitudinal movement with respect each other between a third compressed position and a fourth extended position.

5. The busway system of claim 2 , wherein said busway joint further comprises:

a first plurality of insulators, at least one insulator of said plurality of insulators disposed therebetween each splice plate of said first plurality of splice plates to insulate each splice plate of said first plurality of splice plates from each other.

6. The busway system of claim 2 , wherein said busway joint further comprises:

a second plurality of insulators, at least one insulator of said plurality of insulators disposed therebetween each splice plate of said second plurality of splice plates to insulate each splice plate of said second plurality of splice plates from each other.

7. The busway system of claim 4 , wherein said busway joint further comprises:

a third plurality of insulators, at least one insulator of said third plurality of insulators disposed therebetween at least one splice plate of said third plurality of splice plates to insulate said at least one splice plate of said third plurality of splice plates from each other.

8. The busway system of claim 1 , wherein each splice plate of said first plurality of splice plates, and each said corresponding splice plate of said second plurality of splice plates, and each said corresponding splice plate of said third plurality of splice plates is associated with one of a distinct electrical phase, ground, or neutral.

9. The busway system of claim 1 , wherein said busway joint further comprises:

a housing comprising a first housing; portion, and a second housing portion, at least one of said first and said second housing portions configured and arranged for a longitudinal movement with respect each other, between a first compressed position and a second extended position;

said first, and said second plurality of electrically conductive splice plates being at least partially disposed within said housing.

10. The busway system of claim 9 , wherein a portion of said first housing portion is arranged and disposed to overlap at least a portion of said second housing portion.
