(6) Crimp the terminal lug.
Make sure that:
• All of the strands of the conductor are in the crimp barrel
• The end of the conductor extends farther than the end of the crimp barrel
• If the terminal lug has an insulation grip, the end of the wire insulation is in the insulation
grip of the terminal lug
• If the terminal lug has an insulation grip, the crimp tool is adjusted to give the correct
insulation support. Refer to Paragraph 2.B.
• If the terminal lug does not have an insulation grip, the maximum distance from the end of
the wire insulation of a single wire to the end of the crimp barrel is 0.12 inch for AWG 10 and
smaller, and 0.25 inch for AWG 8 and larger
• The clearance from the end of the conductor is sufficent for the installation of the washer
and the nut.
