Busway Plugs Installation Instructions

Figure 1. Plug mounting.

WARNING: HAZARD AND ELECTRICAL SHOCK
OR BURN! The plug must be turned OFF before
installing on or removing from the busway.
Failure to do so may cause serious injury or
death! It is a good safety to de-energize the
busway before inserting or removing bus plugs.
In the United States, it is necessary to comply
with all Federal and local safety procedures,
including NFPA 70E 2-1.3 directing the use of
appropriate PPE (Personal Protective Equipment)
such as face shield, insulating gloves, and flame
resistant clothing. In Canada, be sure to comply
with the appropriate requirements of the
Canadian Electrical Code. Only properly trained
personnel may install bus plugs on or remove
them from energized busway. In addition, all bus
plug installation instructions must be followed
completely.

Figure 2. Break-Off Tabs

Note the following points concerning busway
plugs:

• Inspect the plug before installing on the
busway.

• Stab fingers have been lubricated with
grease, which should not be removed.

• Dripproof plug-in busway has a dripproof
cover over the outlet. Unscrew the cover and
reattach the cover to the left side of the outlet,
using the screw on the right side of the cover.
This relocates the cover so it is out of the way
for plug insertion.

• The actuator bar polarizes and locates the
plug in the correct position only.

• Plugs are interlocked, permitting engagement
and disengagement with the busway only
when in the OFF position.

• Place the operating handle at the desired
position on the plug and secure it with the
screw provided. The NEC requires the ON

handle position to be up and the OFF handle
position to be down.

• If plug-assist has been furnished on the plug,
the operating handle may be used as a
wrench to operate the mechanism.

• To install a plug where the rear plug hanger
interferes with a joint cap, it is necessary to
remove the break-off tabs, as shown in the
Figure 2.

• On large plugs, drop rod brackets are
provided for auxiliary support of the plug on
the horizontal runs.

CAUTION: Make certain that the bus plug is level
in all orientations with the busway after all
connections are completed. Failure to level the
plug could result in overheating of the plug
connection.

Installing a Plug Not Equipped with Plug-Assist

1. Make sure the device is in the OFF position.

2. Loosen the four bolts on the hanger hooks.

3. Align the actuator bar of the bus plug with the
vertical actuator bar slot on the shutter and
push firmly, the shutter will open and the bus
plug stabs fingers will engage the bus bars.

4. Push the stabs into the full contact with the
busway.

5. Engage the four hanger hooks with the
busway rails and tighten the bolts.

Installing a Plug Equipped with the Plug-Assist

1. Make sure the device is in the OFF position
and the plug-assist indicator is rotated fully
toward the stabs-OUT position.

2. Loosen the four bolts on the hanger hooks.

3. Align the actuator bar of the bus plug with the
vertical actuator bar slot on the shutter and
attach the line end hanger hooks to the bus
rail and tighten.

4. Recheck alignment of actuator and vertical
slot and attach load end hanger hooks to bus
rail and tighten.

5. Engage bus plug by rotating the plug assist
mechanism, the shutter should open and the
bus stab fingers will engage the bus bars. The
pointer should indicate “Stabs-IN”.

NOTE: On the vertically mounted plugs, push up
on the plug to remove the weight of the plug
from the alignment pin before tightening the
bolts in step 4.

WARNING: Be sure that the plug-assist pointer is
lined up with the IN position before turning the
plug on. Failure to do so may result in serious
injury or death.

Removing a Plug

First turn the device OFF. Then follow the
appropriate procedure above in reverse order.

These instructions do not cover all details or variations in equipment nor do they provide for every possible contingency that
may be met in connection with installation, operation, or maintenance. Should further information be desired or should
particular problems arise that are not covered sufficiently for the purchaser’s purposes, the matter should be referred to the GE
