J. Insulation of the Splice - AMP 277156-1 Splices with AWG 8 Wire
(1) Make a selection of an insulation tape from Table 7.
(2) Make a selection of a solvent from Table 7.
(3) With a clean wiper and solvent, clean the splice and a minimum of two inches of the wire from
each end of the splice.
(4) Dry the clean area with a clean wiper.
(5) Wind two layers of tape on the splice. Refer to Figure 21.
(a) Start the first layer of tape a minimum of 2 inches from the end of the splice.
(b) Wind the tape on the splice and a minimum of 2 inches farther than the other end of the
splice.
Make sure that each edge of the tape makes a 50 percent overlap with the tape below it.
(c) Start the second layer a tape where the first layer of tape stops.
(d) Wind the tape on the first layer of tape in the direction of the start of the first layer of tape.
Make sure that:
• Each edge of the tape makes a 50 percent overlap with the tape below it
• The second layer of tape is wound in the opposite direction of the first layer of tape
• The second layer of tape stops where the first layer of tape starts.
