Deadbreak apparatus connectors
•
By hand, turning clockwise, thread insulating plug in as
far as possible.
•
Using a torque wrench and 1" socket complete threading
clockwise until tight. Torque to 55 ft-lbs. See Figure 28.
Step 15.
Check tightness of termination
•
Check tightness by hand by moving T-body forward and
back (perpendicular to the apparatus frontplate). Do not
move side to side as this may loosen the connection.
•
If tight:
• Re-torque to 55 ft-lbs.
•
If loose:
• Remove insulating plug and T-body from apparatus
bushing.
• Inspect threads of the stud and insulating plug for
damage.
• If damaged, replace damaged component and re-install
per previous installation instructions.
• If no damage is found, re-install per previous
installation instructions.
Step 16.
Cap the insulating plug
•
Clean and lubricate inner surface of insulating plug cap
with lubricant supplied.
•
Attach hotstick onto cap ring.
•
Push cap onto insulating plug until it snaps into place.
Refer to Figure 29.
Step 17.
Ground system
•
Connect one concentric neutral wire to drain wire tab of
the T-body or use a separate uninsulated copper wire
(#14 AWG/1.6 mm). Refer to Figure 30.
•
Twist to bundle all concentric neutral wires and connect
to common ground point. Provide sufficient slack to allow
T-body movement to standoff bushing.
