IEC 60050-826:2022

International Electrotechnical Vocabulary (IEV) - Part 826: Electrical installations

IEC 60050-826:2022 gives the general terminology used for electrical installations such as those of residential, industrial or commercial premises. It does not cover systems for distribution of energy to the public or power generation and transmission for such systems. This new edition reviews and complements the previous one. An important aim of the revision is to achieve compliance with IEC 61140:2016. In addition, some new terms have been added from IEC 60364-8-1:2014 and IEC 60364-8-2:2018. It has the status of a horizontal publication in accordance with IEC Guide 108.
This terminology is consistent with the terminology developed in the other specialized parts of the IEV.
This horizontal publication is primarily intended for use by technical committees in the preparation of IEC publications in accordance with the principles laid down in IEC Guide 108.
One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal publications in the preparation of its publications.

Vocabulaire Electrotechnique International (IEV) - Partie 826: Installations électriques

IEC 60050-826:2022 donne la terminologie générale utilisée pour les installations électriques telles que celles à usage résidentiel, industriel ou commercial. Elle ne couvre pas les réseaux de distribution d'énergie au public ou la production et le transport pour de tels réseaux. Cette nouvelle édition constitue une révision de la précédente et complète cette dernière. Elle a essentiellement pour objet la mise en conformité à l’IEC 61140:2016. En outre, de nouveaux termes ont été ajoutés, repris de l’IEC 60364-8-1:2014 et de l’IEC 60364-8-2:2018. Elle a le statut de publication horizontale conformément au Guide IEC 108.
Cette terminologie est en accord avec la terminologie figurant dans les autres parties spécialisées de l'IEV.
La présente publication horizontale est essentiellement destinée à l'usage des comités d'études dans la préparation des publications de l'IEC, conformément aux principes établis dans le Guide IEC 108.
L'une des responsabilités d'un comité d'études est d'utiliser, autant que possible, les publications horizontales lors de la préparation de ses publications.

INTERNATIONAL ELECTROTECHNICAL VOCABULARY –

Part 826: Electrical installations

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.
International Standard IEC 60050-826 has been prepared by IEC technical committee 64:
Electrical installations and protection against electric shock, under the responsibility of IEC
technical committee 1: Terminology.
This third edition cancels and replaces the second edition published in 2004. It constitutes a
technical revision. An important aim of the revision is to achieve compliance with
IEC 61140:2016. In addition, some new terms have been added from IEC 60364-8-1:2014 and
IEC 60364-8-2:2018, and IEV 826-12-02 has been deleted.
It has the status of a horizontal publication in accordance with IEC Guide 108.
The text of this standard is based on the following documents:
