Troubleshooting
WARNING
Stay at least 5 feet (152 cm) below the VacuFuse II
interrupter when operating the Loadbuster tool from
a bucket truck . Operating the Loadbuster tool from
less than 5 feet away is difficult and may result in an
improper opening operation, leading to arcing, faults,
equipment damage, serious injury, or death .
Follow these steps when using S&C’s Loadbuster tool:
STEP 1.
Check for proper resetting of the Loadbuster
tool by extending the tool about 3 inches
(76 mm) by hand. Throughout this travel, an
increasing spring resistance should be felt.
STEP 2.
Fasten the Loadbuster tool to an S&C Universal
Pole not less than 6 feet (183 cm) long (8 feet
[244 cm] for catalog number 5400R3) with the
frame of the tool in line with the pole. As shown
in Figures 14 and 15, the Loadbuster tool must be
attached so it reaches across the front of the
VacuFuse II Self-Resetting Interrupter, and the
Loadbuster tool’s anchor must be hooked to the
attachment hook on the far side of the
VacuFuse II interrupter.
The Loadbuster tool should never be attached
with its anchor hooked on the closest side
of the VacuFuse II interrupter, as shown in
Figures 16 and 17 on page 22. Attaching the
tool in this manner will not only obscure the
operator’s line of vision, but it could also result
in bending stress on the tool, causing improper
disengagement.
