with two screws, Figure 4.22 show a typical example. After
the front rail shipping splice plate(s) have been installed,
remove and retain the two screws holding the rear runner
splice plate. Remove the two screws that are on the rear
runner on the other side of the shipping split. Place the rear
runner shipping splice plate over both sections and on top of
the rear runner. Align the four mounting holes and install the
four screws that were previously retained.
After the splice plates have been installed, run the breaker
lifting device over the assembled shipping splits to check the
alignment of the front rail and rear runner. If necessary,

of the rollers on the breaker lifting device.
On seismic rated equipment, it is necessary to remove the
bracket locking the dolly on the breaker lifting device before
the breaker lifting device can be used, refer to Figure 4.24.
Replace the bracket after breaker installation or removal is
