Communications Bus Wire Specifications: T h e 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 m ust be at least 20
AWG, stranded, and tinned copper. Individual conductors
must be insulated with PVC, PVC/nylon, vinyl, Teflon*,
or polyethylene. An aluminum/pol yester 100% foil shield
and an outer jacket of PVC, PVC/nylon, chrome vinyl, or
Teflon with a minimum operating temperature range of
-- 2 0 _Cto60_C is required. Do not run communication
wire in the same conduit as or next to any AC vol tage
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
ente rs another building, the shields must be connected to
the grounds at a lightning suppressor i n each building (one
point only).

Connecting CCN bus:
NOTE: When connect ing the c ommunication bus cable,
a color code system for the entire network is
recom mended to simplify installation and checkout. See
Table 7 for the recommended color code.
