Install Coupled Bonding Conductor
Return to Task List
The Figure 165, Coupled Bonding Conductor, on page 446 (CBC) connects to the single-point ground
block and runs adjacent to pairs in an associated telecommunications cable. The mutual coupling between
the bonding conductor and the pairs reduces potential differences in terminating equipment.
1 Cut a 10 AWG (#25) (2.5 mm
2
) wire long enough to reach from the system’s single-point ground
block or DC power cabinet Ground Discharge Bar to the MDF CBC block.
2 Connect one end of the 10 AWG (#25) (2.5 mm
2
) wire to the single-point ground block (or
Ground Discharge Bar).
3 Route the wire next to the 25-pair cables connecting to the trunk/auxiliary (purple) field.
4 Tie wrap the 10 AWG (#25) (2.5 mm
2
) wire to the 25-pair cables.
5 Connect the 10 AWG (#25) (2.5 mm
2
) wire to the MDF CBC ground block.
6 Repeat the above steps for each CBC ground wire installed.
