4. ASSEMBLY WITH MORE THAN ONE WIRE
A. General Conditions for Wire Insulation
These conditions are applicable:
• If it is possible, the end of the insulation of all the wires must be held in the area of insulation grip
that makes an overlap with the insulated area of the terminal or splice; refer to Figure 8
• When the dimensions of the crimp tool adjustment and the termination insulation grip support
area permits, the necessary length of heat shrinkable sleeve must be installed on the wires; refer
to Figure 9 and Figure 10.
As an alternative when the applicable conditions are not possible, the end of the insulation of the wires
can be outside the insulation grip of the terminal or splice, but the wires must be supported and
insulated with:
• The applicable Grade and Class of heat shrinkable sleeve; refer to Subject 20-00-11 and
Subject 20-10-14
• A sleeve that has a loose fit over the wires and terminal or splice, but stays tight after heat is
applied
• A sleeve that has a loose fit over the wires and terminal or splice, but is held in position with ties if
it is not possible to apply heat.
