12AWG wire allows for the greatest distance between a power source(BDFB) and the
Alcatel-Lucent 1850 TSS-5 shelf.

Note:
GND and +VB and GND. The dc terminal block can accommodate wire sizes from 12
to 20 AWG, however, if jumpering between positions, for grounding, the maximum
wire size that allows 2-wires into same hole is 16AWG.
