Operating Procedures
Loadmake Operation
●
●
Area must be clear of obstructions or contaminants that
would interfere with the operation of the fused loadbreak
elbow.
●
●
Securely fasten a clampstick to the pulling eye of the
fused loadbreak elbow.
●
●
Place the fused loadbreak elbow over the bushing,
inserting the white arc follower of the probe into the
bushing approximately 2 1/2
"
(65 mm) until a slight
resistance is felt. This will align and stabilize the fused
loadbreak elbow.
●
●
Turn your back to the bushing and grasp the clampstick
securely and obtain good footing. Slam the fused
loadbreak elbow onto the bushing with one quick and
continuous motion.
●
●
Turn around and apply a force to the clampstick to push
the fused loadbreak elbow onto the bushing. A popping
or snapping sound is often heard when this operation is
performed.
●
●
To check that the fused loadbreak elbow is properly
latched apply a gentle pull force to the clampstick. When
latched properly the fused loadbreak elbow will not slide
back off of the bushing.
●
●
As a last operation, push on the clampstick to seat the
fused loadbreak elbow all the way onto the bushing
again. This insures that the fused loadbreak elbow is
latched and was not dislodged during the latching check
in previous step above.
Fault Close
1. It is not recommended that operations be made on
known faults.
2. If a fault is experienced, the fused loadbreak elbow
connector, probe, and the bushing must be replaced.
Loadbreak Operation
●
●
Area must be clear of obstructions or contaminants that
would interfere with this operation.
●
●
Use clampstick to secure standoff insulator or portable
feedthru in bracket. Ground devices to system ground
per appropriate Installation Instructions. All associated
apparatus must also be grounded.
●
●
Secure fused loadbreak elbow eye firmly onto clampstick
and lock.
●
●
Twist clampstick clockwise until the fused loadbreak
elbow rotates slightly on bushing — about 1/4
"
(6 mm).
This action will break any surface friction between outer
surface of bushing and inner surface of fused loadbreak
elbow.
●
●
Withdraw fused loadbreak elbow from bushing with a
fast, firm, straight motion. Minimum amount of travel of
fused loadbreak elbow to break load is 9
"
(230 mm).
●
●
Use clampstick to place fused loadbreak elbow on
lubricated standoff insulator or portable feedthru. (Follow
loadmake instructions.)
●
●
Place an insulated protective cap with ground wire
attached to system ground on any exposed energized
bushing using clampstick. Follow the same operating
procedures as for the fused loadbreak elbow as outlined
above under Loadmake Operation.
