The C-Bus cable features eight single core conductors (four Unshielded Twisted Pairs or UTP), encased in a pink outer sheath that is rated to 240V AC. Pink has been chosen in order to distinguish the C-Bus cabling in an installation.
A second feature of 5005C305B is that, for short runs, the cable may be routed into a switchboard close to mains cable. The outer sheath insulation resistance is suitable for this application.
The illustration above shows the recommended technique for cable termination giving optimum performance, and immunity from electromagnetic interference (EMI).
Note the mutual twist of solid and dotted conductors of opposing coloured conductors. This ensures a good electrical termination, with favorable common mode noise characteristics.
