I-Line Construction

Plug-In Busway 225–600 A

Example of 225–600 A Plug-In Busway

1	Integral Ground Bus (IGB)—furnished as an optional feature for I-Line busway and rated at 50% capacity of the nameplate amperage rating of the busway. The conductor is aluminum and is the top part of the housing itself.
2	Visi-Tite bolt—a double-headed bolt furnished for all joint connectors to ensure proper torque for each connection. A cupped conical washer is also included to ensure equal distribution of pressure across the full joint surface area.
3	Plug-in openings—furnished standard with plug-in openings on 2 ft (61 cm) centers on both sides of I-Line busway. The openings include a hinged door that covers the opening when it is not in use. A 600 A maximum capability is at each plug-in opening. Hangers for the busway fit without blocking access to the plug-in opening.
4	Enclosure—a three-piece formed housing with plug-in openings supported by molded rigid insulators.

NOTE: Insulation for I-Line busway meets UL 857 requirements.

Plug-In Busway 800–5000 A

Example of 800–5000 A Plug-In Busway

1	Molded plug-in opening insulator—adds insulation and support at plug-in contact area.
2	EZ Joint Pak connector assembly—includes like-phase connector on higher ampere ratings with more than one conductor per phase (plug-in bus only).
3	Ground jaw for plug-in unit—has a “blow-on” design similar to phase jaw connection.
4	Fittings—includes elbows, tees, and flanged ends that are easily removed and refitted with the use of our EZ Joint Pak assembly without disturbing adjacent lengths.

NOTE:

Internal barriers are standard on both feeder and plug-in busway. All interior spaces are barriered to stop hot gases.
Hangers fit both feeder and plug-in busway without blocking access to openings.
I-Lineplug-in units (15–1600 A) fit both original and ILine II busway.
I-Line II plug-in busway with sandwich construction also includes the feeder-style features shown in Indoor Feeder Busway 800–5000 A.

Indoor Feeder Busway 800–5000 A

Example of 800–5000 A Indoor Feeder Busway

1	Steel housing channels—provides mechanical strength.
2	Molded extra-strength glass fiber interphase barriers.
3	EZ Joint Pak connector assembly—removable for isolation or maintenance. Includes Visi-Titebolt.EZ Joint Pak connector assembly—removable for isolation or maintenance. Includes Visi-Titebolt.
4	Steel/aluminum housing—reduces hysteresis and eddy current losses on feeder and plug-in busway.
5	Plated aluminum or copper bus bars.
6	Surge clamps for added short circuit strength.
7	Integral Ground Bus (IGB)—two, 1/16-inch thick aluminum bus bar. Also serves as top and bottom housing.

NOTE:

Polyester powder paint process—provides lasting uniform performance.
Housing sizes—the same for I-Line II feeder and plug-in busway. Same accessories fit both.
Insulation for I-Line busway meets UL 857 requirements.

Outdoor Feeder Busway 800–5000 A

Example of 800–5000 A Outdoor Feeder Busway

1	Joint covers—two-piece joint cover with quick-fasten nut for speedy installation of the busway.
2	EZ Joint Pak—same joint pack used on our indoor I-Line II busway is continued in our outdoor feeder design.
3	Flanged collar—simple installation of the joint covers is assisted by a smooth flange surface with a factory-installed joint sealant strip. Removing the sealant’s protective paper covering and installing the joint covers with the quick fasten nut, seal the joint from water contamination.
4	Removable drain plug—outdoor feeder design includes removable drain plugs to allow condensation to escape from the joints. These drain plugs should be removed only as described in the installation instructions for outdoor feeder busway. Outdoor feeder busway can be installed to achieve an IP66 environmental rating with drain plugs and sealing strips located per the I-Line II Outdoor Feeder Busway instruction bulletin no. 45123-922-01.
5	Completed joint—assembled joint with all installation activities complete.

NOTE: Supports are required on 5 ft (152 cm) centers for vertical mounting or 10 ft (305 cm) for horizontal mounting.
