Operating instructions
Loadmake operation
•
Area must be clear of obstructions or contaminations
that would interfere with the operation of the loadbreak
elbow.
•
Securely fasten a clampstick to the pulling eye of the
elbow.
•
Place the loadbreak elbow over the bushing, inserting
the white arc follower of the probe into the bushing
approximately 2” until a slight resistance is felt. This will
align and stabilize the elbow.
•
Turn your back to the bushing and grasp the clampstick
securely and obtain good footing. Slam the elbow onto
the bushing with one quick and continuous motion.
•
Turn around and apply a force to the clampstick to push
the elbow onto the bushing. A popping or snapping
sound is often heard when this operation is performed.
•
To check that the elbow is properly latched apply a gentle
pull force to the clampstick. When latched properly the
elbow will not slide back off of the bushing.
•
As a last operation, push on the clampstick to seat the
elbow all the way onto the bushing again. This insures
that the elbow is latched and was not dislodged during
the latching check in previous step above.
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 elbow eye firmly onto clampstick and lock.
•
Twist clampstick clockwise until the elbow rotates slightly
on bushing–about 1/4” (7 mm). This action will break any
surface friction between outer surface of bushing and
inner surface of elbow.
•
Withdraw elbow from bushing with a fast, firm, straight
motion. Minimum amount of travel of elbow to break load
is 9” (229 mm).
•
Use clampstick to place 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 elbow as outlined above under
Loadmake Operation.
CAUTION
The operator should always use personal protective
equipment (insulated gloves, clampstick and eye
protection) whenever operating the elbow. The operator
should always be in the best possible operating
position, providing firm footing and enabling a secure
grasp of the clampstick, while maintaining positive
control of the elbow before, during and immediately
after operation. If there is any question regarding the
operator’s operating position, de-energize the elbow
before operation. The operator should not be looking
directly at the connector during the moment of circuit
interruption or connection.
