interferes with a joint cap, it is necessary to
remove the break-off tabs, as shown in the
Figure 40B.
 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.
