NOTE
The use of high-quality splice connectors is essential to ensure optimum electrical
integrity. Use the type and size connector best suited to the application.
1. Inspect each end of wire (Figure 11, Item 1). Trim insulation and metal strands (Figure 11, Item 2) of wire back,
as necessary, to ensure integrity of wire.
2. Using wire stripping tool, strip each end of wire (Figure 11, Item 1) to expose length of metal strands
(Figure 11, Item 2) suitable for size of splice connector (Figure 11, Item 3).
3. Insert electrical insulating sleeve onto wire and out of the way. Refer to Heat-Shrinkable Tubing (Electrical
Insulating Sleeving) in this work package.
4. Insert metal strands (Figure 11, Item 2) of each wire (Figure 11, Item 1) fully into splice connector
(Figure 11, Item 3).
5. Securely crimp splice connector (Figure 11, Item 3) to metal strands (Figure 11, Item 2) and to insulation of
wire (Figure 11, Item 1).
6. Secure electrical insulating sleeve onto wire. Refer to Heat-Shrinkable Tubing (Electrical Insulating Sleeving)
in this work package.

HEAT-SHRINKABLE TUBING (ELECTRICAL INSULATING SLEEVING)
0370
Use heat-shrinkable tubing to insulate soldered and crimped electrical connections.
1. Cut length of new tubing twice as long as connection to be covered.
2. Slide tubing onto wire and out of the way before making electrical connection.
3. After making electrical connection, slide tubing into place over electrical connection.
WARNING
DO NOT touch heat-shrinkable tubing for at least 30 seconds after heating. Heat-
shrinkable tubing is hot and will cause burns. Failure to follow this warning may result in
injury to personnel.
4. Using a heat source, apply heat to tubing for approximately 30 seconds, until tubing snugly conforms to shape
of electrical connection.
