(6) For butt splices without an insulation grip, put the wires in the splice. Refer to Figure 29.
Make sure that for each wire:
• 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 splice insulation, the splice insulation makes an overlap
with the wire insulation
• If the wire insulation of a AWG 10 and smaller wire cannot go into the splice insulation, the
end of the wire insulation is a maximum of 0.25 inch from the end of the splice insulation
• If the wire insulation of a AWG 8 and larger wire cannot go into the splice insulation, the end
of the wire insulation is a maximum of 0.37 inch from the end of the splice insulation.
NOTE: The wire insulation, the crimp barrel, and the conductor can be seen through the
insulation of the butt splice.
