Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13297 was prepared by Technical Committee ISO/TC 188.
This third edition cancels and replaces the second edition (ISO 13297:2000) which has been technically
revised.

4 General requirements
4.1 The protective conductor insulation shall be green or green with yellow stripe. Neither colour shall be
used for current carrying conductors.
NOTE The equipotential bonding conductor of the d.c. electrical system, see ISO 0133, also uses green or green
with yellow stripe insulation and is connected to various exposed conductive parts of direct current electrical devices, other
extraneous conductive parts and the d.c. negative ground/earth.
4.2 The protective conductor shall be connected to the craft's d.c. negative ground/earth as close as
practicable to the battery (d.c.) negative terminal except fully insulated systems. See 4.3.
NOTE If an RCD (whole craft residual current device) or an isolation transformer is installed in the main supply circuit
of the a.c. system (8.2), the negative ground terminal of the d.c. system need not be connected to the the a.c. shore
gound (protective conductor).
4.3 For craft shall have a fully insulated d.c. systems, in accordance with ISO 10133, and the a.c. protective
conductor shall be connected to the hull of a metallic hull craft, the craft external ground/earth or the craft
lightning ground plate, if fitted.

from one power source circuit to another shall be made by a means which opens all current carrying
conductors, live and neutral, before closing the alternate source circuit, prevents arc-over between contacts
and is interlocked by mechanical or electromechanical means. Both current carrying conductors, live and
neutral, shall be broken simultaneously when changing power sources.
EXCEPTION Devices that are installed to synchronize with power sources of different origins shall be
installed in accordance with the manufacturer’s instructions and with consideration for reverse power
protection.

4.7 Energized parts of electrical equipment shall be guarded against accidental contact by the use of
enclosures of at least IEC 60529-IP 2X or other protective means which shall not be used for non-electrical
equipment. Access to energized parts of the electrical system shall require the use of hand tools or be at least
IP 2X, unless otherwise specified. A suitable warning sign shall be displayed (see 5.2).
4.8 The neutral conductor shall be grounded (earthed) only at the source of power, i.e. at the onboard
generator, the secondary of the isolation or polarization transformer, or the shore-power connection. The
shore power neutral shall be grounded through the shore power cable and shall not be grounded on board the
craft.
4.9 A galvanic isolator or other suitable device can be fitted in the protective conductor to resist imported
stray galvanic current flow while permitting the passage of a.c. current, if present. Galvanic isolators shall be
designed to withstand the application of power from a short circuit test from a source capable of delivering

the isolator shall be unchanged.
4.10 Reverse polarity indicating devices providing a continuous visible or audible signal shall be installed in
shore power systems and must respond to the reversal of the ungrounded and the grounded conductors if the
polarity of the system must be maintained for the proper operation of the electrical devices in the system, or a
branch circuit is provided with overcurrent protection in only the ungrounded current carrying conductors.
NOTE 1 Reverse polarity indicating devices respond to the reversal of an ungrounded conductor or grounded
conductor only when there is continuity of the protective grounding conductor to shore.
NOTE 2 Reverse polarity indicating devices might not respond to reversals of an ungrounded conductor and the
protective grounding conductor, the grounded conductor and the protective grounding conductor, or three-phase
conductors.
NOTE 3 Reverse polarity indicating devices are not required in systems employing polarization or isolation
transformers that establish polarity on the craft.
4.11 Craft equipped with both d.c and a.c. electrical systems shall have their distribution from either separate
panel boards or from a common one with a partition or other positive means provided to separate clearly the
a.c. and d.c. sections from each other, and be clearly identified. Wiring diagrams to identify circuits,
components and conductors shall be included with the craft.
5 Marking
5.1 Shore-power inlets shall be marked to indicate voltage, current, shock hazard symbol   and read
owner’s manual symbol      .

5.2 A permanently mounted waterproof warning sign shall be located at the panel board on the craft. The
