Busway joint

A busway joint for connecting at least two busbars having a predefined thickness and a common longitudinal axis, the joint comprising:

• at least two substantially rectangular insulators each defining at least a first opening;
• at least two conductive connector plates each defining at least a second opening and a tab press formed from a portion of the material removed to form the second opening, where the tabs extend at substantially 90 degrees from the plates adjacent the second openings for a distance less than the predefined thickness and greater than 50 percent of the thickness;
• and
• at least one fastener disposed within the first and second openings, where the connector plates are located between the insulators and oriented such that the tabs are positioned along the longitudinal axis and one tab is positioned on each side of the fastener, the fastener being configured to force the insulators into contact with the connector plates such that the connector plates are forced into electrical contact with the busbars.

A busway joint for connecting at least two busbars having a predefined thickness, the joint comprising:

• at least two substantially rectangular insulators each defining at least a first opening and fabricated from a section of pultruded insulating material, where the section has an elongated rectangular cross-section including arrowhead shaped end portions;
• at least one conductive connector plate having material press formed to define at least a second opening and a portion of the material from the second opening being press formed into a tab extending at substantially 90 degrees from the plate adjacent the opening for a distance less than the predefined thickness and greater than 50 percent of the thickness;
• and
• at least one fastener disposed within the first and second openings, where the connector plate is located between the insulators and the fastener is configured to force the insulators into contact with the connector plate and the busbars.

A busway joint for connecting at least two phase busbars having a predefined thickness and a common longitudinal axis, and two ground busbars, the joint comprising:

• at least two substantially rectangular insulators each defining at least a first opening and fabricated from a section of pultruded insulating material, where the section has an elongated rectangular cross-section including arrowhead shaped end portions;
• at least two conductive connector plate each defining at least a second opening and a tab press formed from a portion of the material removed to form the second opening, where the tabs extend at substantially 90 degrees from the plates adjacent the second openings for a distance less than the predefined thickness and greater than 50 percent of the thickness;
• conductive top and bottom caps each defining an end cap opening;
• at least one fastener disposed within the first, second and end cap openings, where insulators are located between the top and bottom caps, the connector plates are located between the insulators and oriented such that the tabs are positioned along the longitudinal axis and one tab is positioned on each side of the fastener, the fastener being configured to force one of the caps into contact with the ground busbars, the ground busbars and the other of the caps into contact with the insulators, and the insulators into contact with the connector plates such that the connector plates are forced into electrical contact with the phase busbars;
• and
• an insulating sleeve disposed about the fastener to electrically insulate the fastener from the connector plates.
