Operation with Loadbuster®—The S&C
Loadbreak Tool
S&C’s Loadbuster tool provides low-cost, positive,
and convenient live-switching capability for overhead
distribution switching and protection devices such as
the TripSaver II recloser. Following an opening operation
using a Loadbuster tool, the TripSaverII recloser can be
lifted out of the mounting using an insulated hotstick or an
S&C Universal Pole equipped with a suitable fuse-handling
tting, such as a Talon Handling Tool or a distribution
prong.
WARNING
DO NOT attempt to open a TripSaver II recloser
without using a loadbreak tool such as S&C’s
Loadbuster tool. An arc started by opening a
TripSaver II recloser under load without a loadbreak
tool can cause equipment damage, serious injury, or
death.
Operation
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 27 or 28 on page 22, the Loadbuster
tool must be attached so it reaches across in
front of the TripSaverII recloser. That is, the
Loadbuster anchor must be hooked to the
attachment hook on the far side of the recloser.
The Loadbuster tool should never be attached
with its anchor hooked on the closest side of the
recloser, as shown in Figures 29 or 30 on page
22. 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.
Swing the Loadbuster tool toward the
TripSaverII recloser and pass the Loadbuster
pull-ring hook through the pull-ring on the
TripSaver II recloser. The pull-ring latch will
deflect and, upon complete entry of the pull-
ring, will spring back, locking the Loadbuster
tool to the pull-ring. The Loadbuster tool is
now connected across the upper contacts of the
TripSaverII recloser.
Proper attachment of the Loadbuster tool
to a TripSaverII recloser is shown in Figure 31
on page 23.
