Cable preparation
Step 1
Train cable
•
Position cable vertically so that it is centered between
apparatus bushing and parking pocket, parallel to and 6”
(152 mm) from apparatus frontplate.
•
Provide adequate cable slack for cable movement
between standoff bushing and apparatus bushing.
•
Support cable as needed to maintain position.
•
Cut cable 1.75” (45 mm) from centerline of bushing.
Refer to Figure 14.
Step 2
Remove concentric neutral wires or jacket
ote:N Care should be taken to not cut or score the
neutral conductors when cutting the cable jacket.
•
Measure 12.75” (324 mm) from end of cable. Refer to
Figure 15.
• For jacketed neutral cable, remove jacket to 12.75”
dimension.
• For unjacketed neutral cable, bind neutral wires using
three (3) wraps of tape at 12.75” dimension.
•
Pull back concentric neutral wires. Allow enough extra
concentric neutral wires to connect to ground after installation
and allow movement to insulated standoff bushing.
Step 3
Remove insulation shield
•
Remove insulation shield length 9.75” (248 mm) from
end of cable. Refer to Figure 16.
•
Do not cut or nick insulation.
Step 4
Put tape marker in place
•
Measure 1” (25 mm) from end of insulation shield. Refer
to Figure 16.
•
Wrap two turns of tape to serve as marker for cable
adapter location.
