(6) For butt splices without an insulation grip, put the wire in the splice. Refer to Figure 27.
Make sure that:
• The end of the conductor can be seen in the inspection hole
• The end of the conductor does not make an overlap with the wire stop
• The wire insulation is not in the crimp barrel
• For AWG 10 and smaller wire, the end of the wire insulation is a maximum of 0.13 inch from
the end of the crimp barrel
• For AWG 8 and larger wire, the end of the wire insulation is a maximum of 0.25 inch from
the end of the crimp barrel
• The splice insulation makes an overlap with the wire insulation.
NOTE: The wire insulation, the crimp barrel, and the conductor can be seen through the
insulation of the butt splice.
(7) If it is necessary, remove more insulation from the wire to make a correct fit of the wire in the
splice.
(8) Assemble one end of the splice.
(a) Put the splice in the crimp tool.
(b) Hold the splice in position with light pressure.
