1.0 Cutting And Cable Preparation
1.1 Square cut cable ends to be spliced.
1.2 Split cable approximately 12" (305 mm) between phases.
1.3 If using cable types G or G-GC, pull grounds and ground check conductors out
and tape to cable jacket behind split.
1.4 If using two-conductor cable, cut one lead approximately 6" (150 mm) from end
of cable, leave other conductor approximately 12" (305 mm). Cut corresponding
conductors to match.

1.6 Remove jacket and phase insulation for one-half butt connector length or two
parallel connector lengths from each phase end.
1.7 Taper jacket approximately 1" (25 mm). Taper or bevel ends of insulation to
conductor.
1.8 Scuff and clean 4" (100 mm) of cable jacket beyond each taper or split end.
1.9 Cut ground and ground check conductor to lie in between connections of phases.
2.0 Install Connectors
2.1 Join conductors one at a time using proper connectors (butt, parallel or modified
crow's foot) and crimping tool.
Note: Insulate each conductor in sequence before connecting the next conductor,
ground, or ground check.

3.0 Replace Insulation
3.1 Apply one half-wrapped layer of 3M™Temflex™Vinyl Electrical Tape 1700P
from edge of taper to edge of taper.
Note: Scotch®Glass Cloth Tape 27 or Scotch®Glass Cloth Tape 69, while not
included, may be added and used at this time.

3.2 Apply highly-stretched half-lapped layers of Scotch®Linerless Rubber Splicing
Tape 130C (tacky side DOWN) over 1700P tape and up onto tapers. Build up
half-lapped layers of tape gradually going out on existing insulation ½" (13 mm)
past top of tapers. Tape should be wrapped to a thickness equal to or greater than
the original insulation.

3.4 If cable includes a ground check, the ground check connector should be
wrapped with one half-lapped layer of 3M™Temflex™Electrical Vinyl Tape
1700P extending ¼" (6 mm) onto existing insulation, followed by a half-lapped
layer (tacky side DOWN) of Scotch®Linerless Rubber Splicing Tape 130C
extending ¼" (6 mm) past the 1700P tape, then using the same ¼" (6 mm)
overlap, add a final layer of half-lapped 1700P tape.
3.5 Connect remaining ground wires.

4.0 Replace Jacket
4.1 Start 1" (25 mm) above split or top of taper and apply half-lapped layers of
130C tape (tacky side DOWN) across splice and 1" (25 mm) past end of
opposite split or top of taper. Apply half-lapped layers, filling all voids until
splice area is returned to greater than or equal to original cable profile.

6.0 Prepare Cable
6.1 Position cable ends so that conductor color rotation matches.
6.2 Circle-cut cable jacket approximately 12" (305 mm) from each end. Be sure not
to damage cable conductors.
6.3 Measure approximately 14" (355 mm) from cable end and fully taper cable
jacket down to circle cut.

6.8 Select one conductor and cut conductor approximately 9" (230 mm). Match this
conductor with same color conductor on opposite end.
6.9 Rotate cable so conductor twist will match original cable lay as much as
possible.
6.10 Take next conductor in rotation and cut approximately 6" (150 mm) from end.
6.11 If present, remove color code and/or separator tape for length of phase.
6.12 Remove insulation from ends of conductors for one-half connector length if
using butt splices, or two connector lengths if using parallel splices.
6.13 Pencil insulation for approximately ½" (13 mm), sand smooth and clean with
solvent wipe.
