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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.

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 A 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 parts in the IEC 60364 series, published 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.

• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
For the purpose of this part (IEC 60364-7-708) the requirements of the general Parts 1 to 6 of
IEC 60364 apply.
The IEC 60364-7-7XX parts of IEC 60364 contain particular requirements for special
installations or locations which are based on the requirements of the general parts of
IEC 60364 (IEC 60364-1 to IEC 60364-6). These IEC 60364-7-7XX parts are considered in
conjunction with the requirements of the general parts.
The particular requirements of this part of IEC 60364 supplement, modify or replace certain of
the requirements of the general parts of IEC 60364 being valid at the time of publication of
this part. The absence of reference to the exclusion of a part or a clause of a general part
means that the corresponding clauses of the general part are applicable (undated reference).
Requirements of other 7XX parts being relevant for installations covered by this part also
apply. This part may therefore also supplement, modify or replace certain of these
requirements valid at the time of publication of this part.
The clause numbering of this part follows the pattern and corresponding references of
IEC 60364. The numbers following the particular number of this part are those of the
corresponding parts, or clauses of the other parts of the IEC 60364 series, valid at the time of
publication of this part, as indicated in the normative references of this document (dated
reference).
If requirements or explanations additional to those of the other parts of the IEC 60364 series
are needed, the numbering of such items appears as 708.101, 708.102, 708.103 etc.
In the case where new or amended general parts with modified numbering were published
after this part was issued, the clause numbers referring to a general part in this 701 part may
no longer align with the latest edition of the general part. Dated references should be
observed.

708.521.7.101 Supply for the caravan or tent pitch
The preferred method of supply for feeding the caravan pitch or tent pitch electrical supply
equipment is by means of underground distribution circuits.
708.521.7.102 Underground cables
An underground distribution circuit shall, unless provided with additional mechanical
protection, be buried at a sufficient depth to avoid being damaged, for example by tent pegs
or ground anchors or by the movement of vehicles.
A depth of 0,6 m is generally considered as a minimum depth to fulfill this requirement.
Alternatively the cable may be installed outside the pitch or other area where tent pegs or
ground anchors may be driven.
NOTE For conduit systems buried underground, see IEC 61386-24.
708.521.7.103 Overhead cables or overhead insulated conductors
Every overhead conductor shall be insulated.
Poles and other supports for overhead wiring shall be located or protected so that they are
unlikely to be damaged by any foreseeable movement of vehicles.

708.55.101.1 Every socket-outlet shall comply with IEC 60309-2.
Every socket-outlet shall meet the degree of protection of at least IP44 or such protection
shall be provided by an enclosure.
To prevent the socket contacts being live when accessible, every socket-outlet or connector
shall either comply with IEC 60309-2 and shall be interlocked and classified according to
IEC 60309-1:1999, 6.1.5 or shall be part of an interlocked self-contained product complying
with IEC 60309-4 and classified according to IEC 60309-4:2006, 6.1.101 and 6.1.102.
708.55.101.2 Every socket-outlet shall be located as close as practicable to the caravan
pitch or tent pitch to be supplied.
Socket-outlets shall be installed in the distribution board or in separate enclosures.
708.55.101.3 In order to avoid any hazard due to long connection cables no more than four
socket-outlets shall be grouped together in any one enclosure. To ensure that the degree of
protection is maintained when the socket-outlets are in use, no more than four socket-outlets
shall be mounted within the same enclosure.
Columns (pillars) should be located so as to minimize the need for extension cables to cross
gangways, etc.
708.55.101.4 Every caravan pitch or tent pitch shall be supplied with at least one socket-
outlet.
708.55.101.5 The current rating of socket-outlets shall be not less than 16 A.
708.55.101.6 The lowest part of any socket-outlet shall be placed at a height between 0,5 m
and 1,5 m from the ground. In special cases of extreme environmental conditions, it is
permitted to exceed the stated maximum height of 1,5 m. In such cases, special measures
shall be taken to ensure the safe insertion and removal of plugs.
NOTE This can be necessary if the caravan park or camping park risks being flooded. This can also be necessary
if the caravan park is used during winter after heavy snow falls.
