5 Cables containing insulation materials with different maximum-rated conductor
temperatures should not be bunched together (that is, in a common clip, gland, conduit
or duct). When this is impractical, the cables must be carefully arranged such that the
maximum temperature expected in any cable in the group is within the specifications of
the lowest-rated cable.
6 Cables with protective coverings which may damage other cables should not be
grouped with other cables.
7 Cables having a copper sheath or braiding must be installed in such a way that galvanic
corrosion by contact with other metals is prevented.
8 To allow for future expansion of the system, all cables should be allocated spare
conductor pairs. Also, space within the vessel should be set aside for the installation of
extra cables.

Radio frequency interference
All cables that are to be permanently installed within 9 m (30 ft) of any source of Radio
Frequency (RF) interference such as a transmitter aerial system or radio transmitters, must,
unless shielded by a metal deck or bulkhead, be adequately screened
Suitable screening can be established using sheathing, braiding or other suitable material. In
such a situation flexible cables should be screened wherever possible.
It is important that cables, other than those supplying services to the equipment installed
in a radio room, are not installed through a radio room, high power switch gear or other
potential sources of interference. Cables which must pass through a radio room must be
screened by a continuous metal conduit which must be bonded to the screening of the radio
room at its points of entry and exit.
