Operation
STEP 1.
Check for proper resetting of the Loadbuster Tool
by extending the tool about three inches (77 mm) by
hand. Throughout this travel, an increasing spring
resistance should be felt.
STEP 2.
Fasten the Loadbuster Tool to a universal pole not
less than six feet long (eight feet for Catalog Number
5400R3) with the frame of the tool in line with the
pole.
As shown in Figure 20a or 20b (power fuse shown for
illustration), the Loadbuster Tool must be attached so that it
reaches across in front of
the TripSaver Dropout Recloser.
That is, the Loadbuster tool anchor must be hooked to the
attachment hook
on the far side
of the device. The Loadbuster
Tool should never be attached with its anchor hooked on the
closest side of the fuse cutout or other device as shown in
Figure 20c or 20d. Attaching the tool in this manner will not
only obscure the operator’s line of vision, but also result in
bending stress on the tool, causing improper disengagement.
When the Loadbuster Tool is properly attached as shown
in Figure 20a or 20b, a downward pull of the pole to open the
TripSaver Dropout Recloser extends the Loadbuster Tool and
charges an internal spring. At a predetermined point in the
opening stroke, a trigger inside the tool trips, releasing the
charged spring—thus separating the internal contacts and
interrupting the circuit. Successful operation is independent
of the speed with which the TripSaver Dropout Recloser is
opened.
Proper attachment of Loadbuster Tool to a TripSaver
Dropout Recloser is shown in Figure 21 on page 22.
When operating from a bucket truck, stay at least five
feet below the device.
Although many words and illustrations are used here to
describe operation of the Loadbuster Tool, correct techniques
can be mastered quite easily. It is advisable, however, to spend
a reasonable amount of time practicing with the Loadbuster
Tool on a de-energized TripSaver Dropout Recloser.
NOTICE
DO NOT
attempt to use the Loadbuster Tool while climb-
ing a pole . Engagement of the Loadbuster Tool in this
position is difficult and may result in an improper opening
operation .
