Pow-R-Way III plug-in busway (Figure 11 and Table 4
and Table 5)
•
225 to 5000 A copper
•
225 to 4000 A aluminum
Straight sections of plug-in busway are made only in 24.00 inch
(609.6 mm) incremental lengths with a maximum length of 10 ft
(3 m). Figure 11 depicts the configuration of plug-in busway and
Pow-R-Bridge for the available ampere ratings. See Table 4 below
for reference to the proper configuration.

Table 5 below illustrates the quantity of plug-in openings per side
that are available per standard section.

Each section will include one, factory-installed Pow-R-Bridge
mounted to the left end of the busway (with the “T” label to the
top, when viewing the bus from the “F” side). Each Pow-R-Bridge
will have a “T” label that must always match the “T” orientation of
the busway.
Plug-in outlet
The plug-in outlet and cover are made from a durable, high-strength,
polycarbonate material, which is rated as Class B, 130 °C, insulation.
The plug-in cover is designed to protect the contact surfaces and to
prevent the entry of dirt, dust, or moisture. The cover has a positive
screw close feature that prohibits the opening of the cover without
the use of a tool. The cover is also Utility “leadlock” sealable.
As a countermeasure to the effects of thermal expansion and
mechanical vibration, the plug-in outlet is secured to the busway
housing with high tensile strength locking hardware.
