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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 188, Small craft.
This fourth edition cancels and replaces the third edition (ISO 13297:2012), of which it constitutes a
minor revision. The main changes are:
— deletion of Annex E;
— replacement of Annex D;
— correction of references in 14.1 indent e) by replacing 4.8 with 4.7 and in 14.3 by replacing 4.6 with 4.7;
— update of reference to ISO 10133.

or green with a yellow stripe insulation and is connected to various exposed conductive parts of d.c. electrical
devices, other extraneous conductive parts and the d.c. negative ground/earth.
4.2 For crafts having a fully insulated d.c. system in accordance with ISO 10133, the a.c. protective
conductor shall be connected to:
a) the hull of a metallic hulled craft;
b) the craft’s external ground/earth or ground plate for non-conductive hulls.

---------------------- Page: 14 ----------------------
SIST EN ISO 13297:2015
ISO 13297:2014(E)
4.3 The hull of a metallic hull craft shall not be used as a circuit conductor.
4.4 The a.c. protective conductor(s) shall be provided with a final (single) connection to the hull of a
metallic hull craft, or if the craft has a non-metallic hull, to the main grounding/earthing point of the craft.
4.5 On metallic hulls, the point of connection of the protective conductor shall be located above any
anticipated water accumulation.
4.6 Metallic housings or enclosures of permanently installed a.c. electrical appliances shall be connected
to the protective conductor system in the craft.
4.7 Individual circuits shall not be capable of being energized by more than one source of electrical
power at a time. Each shore power inlet, generator or inverter is a separate source of electrical power.
The transfer from one power source circuit to another shall be made by a means which opens all live
conductors, active (phase) and neutral, before closing the alternate source circuit, to prevent arc-over
between contacts, and should be interlocked by mechanical or electromechanical means. The conductors
of both circuits-carrying conductors, active (phase) and neutral, shall be broken simultaneously when
changing power sources.
The requirements for overcurrent protection and sizing of the switch are found in Clause 7. A combination
of power sources may be used provided that:
— the device is constructed and tested to an applicable recognized standard;
— the device includes anti-islanding protection;
— the device includes personnel protection against backfeeding; and
— the installation is performed according to the manufacturer’s instructions.
4.8 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).
4.9 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, the shore power connection or
inverter. The shore power neutral shall be grounded (earthed) through the shore power cable and shall
not be grounded (earthed) on board the craft or:
a) for systems using an isolation transformer or polarization transformer, both the generator or
inverter neutral and the transformer secondary neutrals may be grounded at the a.c. main grounding
bus instead of at the generator, inverter, or transformer secondaries;
b) for systems using an isolation transformer or polarization transformer, or no shore power provision,
both the generator or inverter neutral and the transformer secondary neutrals may be ungrounded
provided double-pole protection and switching is installed.
4.10 When an optional galvanic isolator is fitted in the protective conductor to resist imported stray
galvanic current flow while permitting the passage of a.c. current, failure of the isolator shall not result in
an open circuit.
4.11 Reverse polarity indicating devices providing a continuous visible or audible signal shall be installed
in shore power systems and shall respond to the reversal of the active (phase) and the neutral conductors,
if the polarity of the system has to be maintained for the proper operation of the electrical devices in

the system. Otherwise, a branch circuit shall be provided with overcurrent protection in only the active
(phase) conductors. This does not apply for the systems indicated below in a) and b).
Reverse polarity indicating devices are not required on craft employing:
a) unpolarized systems using double-pole branch circuit protection;
b) polarization or isolation transformers that establish polarity on the craft.
NOTE 1 Reverse polarity indicating devices might not respond to reversals of a live conductor and the
protective conductor.
NOTE 2 Reverse polarity indicating devices respond to the reversal of an active (phase) conductor or grounded
conductor only when there is continuity of the protective conductor to shore.
4.12 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 shall be clearly identified. Wiring diagrams
to identify circuits, components and conductors shall be included with the craft.
NOTE After completing an a.c. installation it is recommended to perform a system test according to Annex C.

the electricity warning symbol (ISO
