with a rm, steady pull until it is extended to its
maximum length. See Figure 5. Avoid jerking
and hesitating. The resetting latch will keep it
open. Generally, there will be no indica tion of
circuit interruption but minor arcing may be
noted at the pull-ring hook and at the anchor,
particu larly when interrupting load currents

will be that of the Loadbuster tool tripping.

interruption, rst raise it slightly and disengage
the anchor from the attachment hook.
When the Loadbuster tool is raised, the
open gap distance is reduced. Careless
manipulation could decrease the open gap
to the point where flashover will occur.
Next, bring the power fuse toward its fully Open posi-
tion, as illustrated in Figure 6. (S&C recommends this
procedure as uniform practice because disconnects will
not necessarily open fully by gravity.)
Remove the Loadbuster tool from the pull-ring
by turning the pole. This will def lect the pull-ring
latch to release the pull-ring. On fuse cutouts, fuse
limiters or power fuses on which the fuse tube or
power fuse will drop fully open by gravity, it may be
preferred to remove the Loadbuster tool by "rolling" it
off both the attachment hook and pull-ring at the same
time merely by twisting the pole after the Loadbuster
tool has been tripped and fully extended. To perform this
operation easily and smoothly, always roll the Loadbuster
tool so it rotates in an upward direction.
