LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES –

Part 7: Assemblies for specific applications such as marinas, camping
sites, market squares, electric vehicles charging stations

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.
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.
The main task of IEC technical committees is to prepare International Standards. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification.
This document is being issued in the technical specification series of publications (according
to the ISO/IEC Directives, Part 1, 3.1.1.1) as a “prospective standard for provisional
application” in the field of SC 17D because there is an urgent need for guidance on how
standards in this field should be used to meet an identified need.
This document is not to be regarded as an “International Standard”. It is proposed for
provisional application so that information and experience of its use in practice may be
gathered. Comments on the content of this document should be sent to the IEC Central
Office.

A review of this technical specification will be carried out not later than 2 years after its
publication with the options of: extension for another 3 years; conversion into an International
Standard; or withdrawal.
IEC/TS 61439-7, which is a technical specification, has been prepared by subcommittee 17D:
Low-voltage switchgear and controlgear assemblies, of IEC technical committee 17:
Switchgear and controlgear.
The text of this technical specification is based on the following documents:
FDIS Report on voting
17D/478/FDIS 17D/482/RVD

Following the result of the vote on the FDIS, a questionnaire was circulated, leading to the
decision to publish the project as a Technical Specification.
Questionnaire Result of voting
17D/487/Q 17D/494/RQ

Full information on the voting for the approval of this technical specification can be found in
the report on voting indicated in the above table.
This technical specification is to be read in conjunction with IEC 61439-1. The provisions of
the general rules dealt with in IEC 61439-1 (hereinafter referred to as Part 1) are applicable to
this technical specification where they are specifically cited. When this technical specification
states “addition” “modification” or “replacement”, the relevant text in Part 1 is to be adapted
accordingly.
Subclauses that are numbered with a 101 (102, 103, etc.) suffix are additional to the same
subclause in Part 1.
Tables and figures in this Part 7 that are new are numbered starting with 101.
New annexes in this Part 7 are lettered AA, BB, etc.
In this standard, terms written in small capitals are defined in Clause 3.
The reader’s attention is drawn to the fact that Annex CC lists all of the “in-some-country”
clauses on differing practices of a less permanent nature relating to the subject of this
technical specification .
A list of all parts of the IEC 61439 series, under the general title Low-voltage switchgear and
controlgear assemblies can be found on the IEC website.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

contained components, such as circuit breakers, fuse switches, electronic equipment, etc.
which comply with the relevant product standards.
NOTE 3 Where electrical equipment is directly connected to public low voltage supply system and equipped with
a meter for billing of the legal provider of the low voltage supply, particular requirements based on national
regulations apply, if any.
