STEP 1
CABLE TRAINING
1.
Train cable to ensure slack for ease of operation.
2.
An extra length of concentric neutral wires or grounding braid is needed to faciliate hotstick operation and connection of
the neutral to the tank ground. This can be accomplished by either of two methods: 1. Tape mark the bushing centerline
and pull extra cable to 24--26” beyond the bushing centerline; 2. Proceed to Step 1.D., connect the neutral wires to the
tank ground with a jumper or braid.
3.
Unwrap the neutral wire back past the bushing centerline.
4.
Cut excess cable squarely at the centerline of the bushing.
STEP 2A
CABLE PREPARATION CONCENTRIC NEUTRAL WIRES
1.
Wrap one strip of mastic, stretching slightly, around jacket.
2.
Bend all of the neutral wires straight back over the mastic
and along the cable. Press the wires into the mastic.
3.
Wrap the second strip of mastic completely around the
outer jacket, overlapping the neutral wires imbedded into
the first mastic strip. Use the third strip of mastic, if needed,
to build--up the outer diameter in the area of the first mastic
location. Cover all mastic with vinyl tape.
4.
Remove insulation shield and insulation from the cable end.
Cut squarely taking care not to nick conductor.
5.
Wire brush bare aluminum conductors and immediately place
compression lug over bushing. Rotate to spread inhibitor.
Position compression lug so the CONTACT THREADED
HOLE ALIGNS WITH THE BUSHING BORE. (Refer to crimp
chart packaged with compression lug for recommended crimp
tool information.) Start crimp at the crimp line mark. Rotate

each successive crimp. Carefully wipe excess inhibitor
from the outside of the lug and cable.
6.
Remove insulation shield as shown. Bevel insulation end
1/8” max.
7.
Thoroughly clean insulation to remove all traces of dirt or
excess inhibitor.
