8.0 Operating Instructions

8.1 Before Loadmake or Loadbreak Operation:

Area must be clear of obstructions or contaminants that would interfere with the operation of the connector. This position
should allow you to establish firm footing and enable you to grasp the shotgun stick securely, maintaining positive control
over the movement of the loadbreak connector before, during and directly after the operating sequence. Because of the
control, speed and force required to engage or disengage the elbow, certain operating positions are more advantageous than
others. If there is some question as to proper operating position, it is recommended that the connectors be operated de-
energized. Do not connect two different phases of a multiple-phase system. Before closing a single-phase loop, make certain
both ends of the loop are the same phase.

8.2 Loadmake Operation

• Area must be clear of obstructions or contaminants that would interfere with the operation of the loadbreak elbow.

• Securely fasten a shotgun stick to the pulling eye.

• Place the loadbreak elbow over the bushing, inserting the loadbreak probe into the bushing until the first slight resistance is

felt. Resistance is felt when the arc follower portion of the loadbreak probe first meets the female contact of the bushing.

• Immediately thrust the elbow onto the bushing with a fast, firm, straight motion, with sufficient force to latch the elbow

to the bushing.

8.3 Fault Close

• It is not recommended that operations be made on known faults.

• If a fault is experienced, both the elbow connector and the bushing must be replaced.

8.4 Loadbreak Operation

• Securely fasten a shotgun stick to the pulling eye.

• Without exerting any pulling force, slightly rotate the connector clockwise in order to break surface friction between the

elbow and bushing.

• Withdraw the connector from the bushing with a fast, firm, straight motion, being careful not to place the connector near

a ground plane.

• Place connector on appropriate accessory device, following the operating instructions for that accessory.
