JUMPER WIRING
Before You Begin
Before running cross-connect jumper wire, craft personnel should become familiar with the numbering
sequence used in the terminal as described in Wire Pair Identification and Feeder Pairs.
Feeder and distribution fields are color-coded. Feeder cables are terminated in the green field and distribution
cables are terminated in the blue field.
Begin by terminating each 22 AWG "G" or 24 AWG "F" cross-connecting jumper wire pair as described in
Terminating Jumper Wires on CQF Blocks or Terminating Jumper Wires on RLS Blocks.
Terminating Jumper Wires on CQF Blocks
Perform the following steps to terminate a jumper wire pair on a CQF terminal block in the feeder field:
1. Pull enough jumper wire from the spool mounted on the housing door to reach the assigned feeder
cable terminal binding post (see
Figure 8 ).
Figure 8:
Pulling Jumper Wire
2. Terminate the jumper wire on the terminal binding post as shown below (see Figure 9 ).
•
Strip approximately
1
/
2
-inch of insulation from the end of the jumper wire. Do not nick the
conductor.
•
Loosen the screw on the binding post until the first washer rides out in front of the terminal silo.
3. Place the wire between the washers on the terminal binding post. Tighten securely, but do not over
tighten (see
Figure 10 ).
