Preparation of cables to be spliced
Step 1
Overlap both cables.
Locate the splice centerline as shown in Figure 1.
On cable #2 measure out 24" (610 mm) from the splice
centerline and cut off the cable. (This will ensure there is an
adequate length of concentric neutral wire to reconnect the
neutral after splice installation.)
Cut off cable #1 at the splice centerline with a smooth
square cut.
Remove the outer jacket of cable #2 to 30" (762 mm) and
remove the outer jacket of cable #1 to 12" (305 mm).
Fold back the concentric neutral wires.
Cut off cable #2 at the splice centerline with a smooth square
cut.
Check the jacket strip back dimensions from the splice
centerline to the outer jacket cutoff.
Step 2
Measure from the end of both cables and remove 3-5/8" (92
mm) of the semi-con insulation shield. (See Figure 2).
Step 3
Measure back from the end of both cables and remove
1-1/8" (29 mm) of the cable insulation, exposing the bare
conductor. Remove sharp edge of insulation by beveling at
45° angle for approximately 1/8" (3 mm). (See Figure 3).
Clean the cable insulation with an approved cleaner. Wipe
the cleaner towards the insulation shield only.
