IEC 60364-7-709:2007

Low-voltage electrical installations - Part 7-709: Requirements for special installations or locations - Marinas and similar locations

The particular requirements specified in this part of IEC 60364 apply only to circuits intended to supply pleasure craft or houseboats in marinas and similar locations. The particular requirements do not apply to the supply of house boats if they are directly supplied from the public network. The particular requirements do not apply to the internal electrical installations of pleasure craft or house boats. For the remainder of the electrical installation of marinas and similar locations the general requirements of IEC 60364 together with the relevant particular requirements of IEC 60364-7 apply. This second edition of IEC 60364-7-709 cancels and replaces the first edition, published in 1994. It constitutes a technical revision. The major changes with regard to the previous edition concern: - the removal of the requirements for the electrical installation in pleasure craft as these are now covered by IEC 60092-507; - the requirements of this part have been aligned with those in other parts of IEC 60364.

Installations électriques à basse tension - Partie 7-709: Exigences pour les installations ou emplacements spéciaux - Marinas et emplacements analogues

Les exigences particulières spécifiées dans la présente partie de la CEI 60364 s'appliquent seulement à l'alimentation des navires de plaisance ou fluviaux dans les marinas et emplacements analogues. Les exigences particulières ne s'appliquent pas à l'alimentation des navires de plaisance ou fluviaux si ils sont directement alimentés depuis le réseau public. Elles ne s'appliquent pas aux installations électriques intérieures des navires de plaisance ou fluviaux. Les installations électriques autres que celles concernant les circuits terminaux des marinas font l'objet des exigences générales de la CEI 60364, ainsi que des exigences particulières de la CEI 60364-7. Cette deuxième édition de la CEI 60364-7-709 annule et remplace la première édition, parue en 1994. Elle constitue une révision technique. Les modifications principales par rapport à l'édition précédente sont les suivantes: - la suppression des exigences pour les installations électriques des navires de plaisance car elles sont maintenant traitées dans la CEI 60092-507; - les exigences de cette partie ont été alignées avec celles des autres parties de la série CEI 60364.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60364-7-709 has been prepared by IEC technical committee 64:
Electrical installations and protection against electric shock.
This second edition of IEC 60364-7-709 cancels and replaces the first edition, published in
1994. It constitutes a technical revision.
The major changes with regard to the previous edition concern:
− the removal of the requirements for the electrical installation in pleasure craft as these
are now covered by IEC 60092-507;
− the requirements of this part have been aligned with those in other parts of IEC 60364.

– 4 – 60364-7-709 © IEC:2007
The text of this standard is based on the following documents:
FDIS Report on voting
64/1573/FDIS 64/1588/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The reader’s attention is drawn to the fact that Annex C lists all of the “in-some-country”
clauses on differing practices of a less permanent nature relating to the subject of this
standard.
A list of all the parts in the IEC 60364 series, under the general title Low-voltage electrical
installations, can be found on the IEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
The requirements of this part of IEC 60364 supplement, modify or replace certain of the
general requirements contained in Parts 1 to 6 of IEC 60364.
The clause numbering appearing after 709 refers to the corresponding parts or clauses of
IEC 60364, Parts 1 to 6. Numbering of clauses does not, therefore, necessarily follow
sequentially. Numbering of figures and tables takes the number of this part followed by a
sequential number.
The absence of reference to a part or a clause means that the general requirements
contained in Parts 1 to 6 of IEC 60364 are applicable.

International Standard IEC 60364-7-709 has been prepared by IEC technical committee 64:
Electrical installations and protection against electric shock.
The major changes with regard to the previous edition concern:
– the removal of the requirements for the electrical installation in pleasure craft as these are
now covered by IEC 60092-507;
– the requirements of this part have been aligned with those in other parts of IEC 60364.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The reader’s attention is drawn to the fact that Annex C lists all of the “in-some-country”
clauses on differing practices of a less permanent nature relating to the subject of this
standard.
A list of all the parts in the IEC 60364 series, under the general title Low-voltage electrical
installations, can be found on the IEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the stability date indicated on the IEC web site under
