2.4.3. Installing Wires in Receptacle Contact Springs

between the conductor wire and the receptacle contact spring. Table 2-1 identifies the
correct crimping tool to be used when installing wires in a receptacle contact spring.

1. Strip 3/16 in. (0.187 in. or 0.47 cm.) of insulation from the end of the wire.
2. Place the receptacle contact spring into the jaws of the proper crimping tool.
When using only one terminal, of any wire size, use the shortest terminal.
3. Partially close the crimping tool jaws against the receptacle contact spring to hold
it in place. (Do not crush the receptacle contact spring barrel at this time.)
4. Insert the stripped end of wire all the way into the receptacle contact spring
barrel. Squeeze the tool handles until crimping is completed and the jaws
release. When using both terminals, it is more convenient to attach the first wire
to the longest terminal.
