3)
Route two 8-6AWG conductors (black/red) through the BAT-
Expansion conduit.

6)
Route one CAT5/6 cable through the COM-Expansion conduit.
b.
Use a crimping tool to crimp an RJ-45 connector on each end of the cable. CAT5/6
cables have 8 wires (four twisted pairs). Two wiring standards exist: T-568B and T-
568A, as shown below. Either standard may be used, as long as both ends of the
cable use the same wiring standard.
