• The selection of the correct sealed splice configuration, refer to Paragraph 1.C.
Refer to Figure 114.
(1) Make a selection of a butt splice from Table 15.
Make sure that the splice has the smallest CAU range that can accept the total CAU of the
conductors. Refer to Paragraph 1.D. for the procedure to calculate the CAU of the conductor.
(2) Find the crimp barrel size of the splice from Table 15.
(3) Make a selection of a crimp tool from Table 46.
(4) Make a selection of a Temperature Grade D insulation tape from Table 52.
Make sure that the tape has a width of 0.5 inch minimum to 1.0 inch maximum.
(5) Make a selection of a Temperature Grade D heat shrinkable sleeve from Table 51.
Make sure that the sleeve has the smallest diameter that can be put on the splice assembly.
NOTE: For alternative heat shrinkable sleeves, refer to Subject 20-00-11.
(6) Cut the necessary length of the sleeve.
Make sure that the sleeve extends a minimum of 1.5 inches farther than each end of the splice.
