Repairing Damaged Wire Insulation
If the wire insulation has been chafed, or broken, enough to show the conductive portion of the wire, and the wire is not damaged, determine the length of insulation that needs to be repaired. If the repair is less than 280 mm (11 in), cut the wire within the damaged area. Then slide the appropriate heat shrink tubing (listed below) over the wire, and repair the wire by splicing the wires together. Refer to Splicing Copper Wire Using Splice Sleeves (Splicing Copper Wire Using Splice Sleeves). Once the wire is spliced together slide heat shrink tubing over the damaged area and apply heat to seal the repaired wire.
If the wire is damaged, or the damaged area is larger than 280 mm (11 in), then replace the damaged wire by splicing in a new section of wire. Refer to Splicing Copper Wire Using Splice Sleeves (Splicing Copper Wire Using Splice Sleeves).
