Installing an End Box
An end box, as shown in Figure 16, is available to
isolate phases and seal the end of a run. The
installation process is as follows:
1. Place the box over the end of the busway.
2. Insert the housing spacer and align it with the
U-type clip and the end box mounting holes.
3. Secure the end box to the busway with the
5/16" x 2" screws provided.

Installing and Removing Busway Plugs
WARNING: HAZARD OF 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 practice 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.
