CAUTION
THE O.D. OF THE WIRE INSULATION IS VERY IMPORTANT. MAKE SURE
THAT FOR THE SPECIFIED SPLICE IN TABLE 1 OR TABLE 2, THE O.D OF
THE WIRE INSULATION IS NOT MORE THAN THE MAXIMUM O.D.
SPECIFIED.
CAUTION
IF THE O.D. OF THE WIRE IS LESS THAN THE MINIMUM O.D SPECIFIED,
THE O.D. OF THE INSULATION MUST BE INCREASED TO MAKE A SEAL
IN THE SPLICE.
(3) Remove the necessary length of the insulation from the end of each wire.
Refer to:
• Table 10
• Subject 20-00-15 for the insulation removal procedures.
Make sure that the end of each wire has not been crimped before.
(4) If the O.D. of the wire insulation is less than the minimum O.D. specified in Table 1 or Table 2,
increase the O.D. of the wire.
For the procedure to increase the O.D. of the wire insulation with:
• Layers of tape, refer to Paragraph 4.F.
• Heat shrinkable sleeves, refer to Paragraph 4.G..
