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
grounding elbow.
Place the grounding elbow over the bushing, inserting the
white arc follower of the probe into the bushing approxi-
mately 1-1/2” (38 mm) 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 latch-
ing check in previous step above.
Step 7
Repeat process
Repeat Steps 1 through 6 on opposite end of cable.
Step 5
Test
Using an appropriate voltage sensing meter, test through
the load side 600 A loadbreak bushing interface to verify
circuit is de-energized. See Figure 20.
Step 6
Install grounding elbow
If circuit is de-energized, install Cleer 600 A, 15/25 kV
grounding elbow cable to system ground. Install grounding
elbow on load-side 600 A loadbreak interface. See Figure 21.

WARNING
All associated apparatus must be de-energized during
installation or maintenance.
WARNING
Do not ground energized cable.
WARNING
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. Failure to comply could
result in death or serious injury.
WARNING
This procedure must be performed on both ends of the
cable for complete grounding.
