• The end of each conductor does not make an overlap with the wire stop
• The end of each wire insulation is a maximum of 0.19 inch from the end of the
insulation grip.
(c) If it is necessary, remove more insulation from the end of the wire to make the wire fit
correctly in the splice.
(d) Wind a layer of the insulation tape on each wire. Refer to Figure 103.
Make sure that:
• The edge of the tape is aligned with the end of the wire insulation
• The tape goes around the circumference of the wire a minimum of two times
• The tape makes a 100 percent overlap.
(8) Remove the necessary length of insulation from the end of the wire for the side of the splice
assembly with one wire.
Refer to:
• Figure 102
• Table 84 for the insulation removal length for a wire that can go into the insulation grip
• Table 85 for the insulation removal length for a wire that cannot go into the insulation grip
• Subject 20-00-15 for the insulation removal procedures.

(9) Assemble the end of the butt splice with two wires.
(a) Put the splice in the crimp tool.
(b) Hold the splice in position with light pressure.
(c) Put the wires in the splice. Refer to Figure 103.
