(5) For butt splices with an insulation grip, put the wire in the splice.
Refer to:
• Figure 25 for the position of the wire in the splice with the wire insulation in the insulation
grip
• Figure 26 for the position of the wire in the splice with the wire insulation out of the
insulation grip.
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
• If the wire insulation can go into the insulation grip, the insulation grip makes an overlap with
the wire insulation
• If the wire insulation cannot go into the insulation grip, the end of the wire insulation is a
maximum of 0.13 inch from the end of the insulation grip
• 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.
