Communications Bus Wire Specifications: The CCN
Communication Bus wiring is field- - supplied and
field- - installed. It consists of shielded 3- - conductor cable
with drain (ground) wire. The cable selected must be
identical to the CCN Communication Bus wire used for
the entire network.
See Table 6 for recommended cable.

NOTE: Conductors and drain wire must be at least 20
AWG, stranded, and tinned copper. Individual conductors
must be insulated with PVC, PVC/nylon, vinyl, Teflon, or
polyethylene. An aluminum/polyester 100% foil shield and
an outer jacket of PVC, PVC/nylon, chrome vinyl, or Teflon
with a minimum operating temperature range of - - 20_C to
60_C is required. Do not run communication wire in the
same conduit as or next to any AC voltage wiring.
The communication bus shields must be tied together at
each system element. If the communication bus is entirely
within one building, the resulting continuous shield must
be connected to ground at only one single point. If the
communication bus cable exits from one building and
enters another building, the shields must be connected to
the grounds at a lightning suppressor in each building (one
point only).
