Splicing A Three-Conductor Cable

Splicing three-conductor cables together should be avoided whenever possible. However, if an

existing Pro-Read

Pit receptacle is not in an appropriate location for replacement by an MIU, it

may be necessary to splice the cable and extend it to an appropriate location.

Follow these steps to splice a three-conductor cable:

1. Remove the receptacle from the Pit.

2. Remove the wires from the receptacle.

3. Cut away the exposed copper from each wire.

4. On the three-conductor cable to be spliced, strip off at least 1" of the outer jacket. Do not strip

the insulation from the individual wires.

5. Match up one pair of colored wires (Black to Black, Green to Green, and Red to Red) and insert

the matching-colored pair into a Scotchlok (Figure 2.13).

Note: The Pro-Read

encoder

must be programmed for three-wire mode using a Pro-Read

programmer and its ten-digit TDI format. Do this through the Pro-Read

receptacle before

removing the receptacle.

6. Using a Scotchlok crimping tool or a pair of Channel locks, squeeze the “button” on the

Scotchlok until it is completely flat (Figure 2.14).
