Install Coupled Bonding Conductor Wires

This is a conductor that connects to the single-point ground block and runs adjacent to pairs in
an associated cable. The mutual coupling between the CBC and the pairs reduces potential
differences in terminating equipment. The conductor consists of a 10 AWG (#25) (6 mm
terminated at the CBC ground terminal bar at the Main Distribution Frame (MDF).

Cabinets
NOTE:
The wire in the next step must be sized for a maximum voltage drop of 0.5 VDC in each
leg of the DC distribution. In this example 1 AWG is used.

NOTE:
The wire must be at least as large as the largest distribution wire in the S8700
Multi-Connect configuration (required by UL). In this example 1 AWG is used.

Crimp terminal lugs on each end of the wire. Terminal lugs are furnished as part of
D-181895, Kit of Parts (Comcode 105434559).
At the DC power cabinet, connect the wire to the Ground Discharge Bar.
Route the wire through one of the holes in the side of the cabinets and terminate it on the
Ground Connection Terminal in the DC battery cabinet.
At the DC power cabinet, connect a 1 AWG (#70) (44 mm

Route the ground wire out of the cabinet and terminate it on the approved ground. The
approved ground must be identified with a grounding tag (FORM 15657NR or
equivalent). See Approved
