From the end of each conductor cutback remove 3½" (90 mm) of braid or tape
metallic shielding.
1.11
Remove cable color-coding to ¼" (6 mm) from edge of shielding.
1.12
Remove insulation from ends of conductors for one-half connector length
plus ¼" (6 mm).
1.13

2.0 Connect Phase Conductors
2.1
Join power conductors with proper connectors and appropriate crimping tool.
Make certain conductors butt up to center indents of connector.
Note: Ground wires and ground check will be joined later.
3.0 Apply Primary Insulation
3.1
Apply one half-lapped layer of 3M
™
Temflex
™
Electrical Vinyl Tape 1700P from
edge of taper to edge of taper, making sure to completely cover edges of the
connector
NOTE: 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 to 1/8" (3
mm) from edge of original color coding. Tape should be wrapped to a thickness
equal to or greater than original insulation.
