INSTALLATION COUPLERS INTENDED FOR PERMANENT
CONNECTION IN FIXED 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 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 61535 has been prepared by technical committee 23: Electrical
accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23/466/FDIS 23/471/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.

INSTALLATION COUPLERS INTENDED FOR PERMANENT
CONNECTION IN FIXED INSTALLATIONS
1 Scope
This standard applies to two up to five wire installation couplers including earth, if provided,
with a rated voltage up to and including 500 V a.c. and a rated connecting capacity up to and
²
including 10 mm for permanent connection in indoor electrical installations. Installation
couplers with additional contacts for voltages other than mains voltages are outside the scope
of this standard.
NOTE 1 Installation couplers according to this standard are used e.g. in prefabricated buildings, installation
cavities, such as suspended floors and ceilings, or cable tray systems, cable ladder systems, cable ducting
systems and cable trunking systems or in commercial show rooms, in partition walls and in any similar application
or in furniture complying with IEC 60364-7-713.
NOTE 2 This standard may be used as a guide for installation couplers with additional contacts for voltages other
than mains voltages.
NOTE 3 In the UK, where installation couplers have more than 5 wires, they shall meet the requirements of
IEC 61535 as though they were included in the scope and shall be tested in such a way that all of the mains
voltage pins are subjected to the same level of testing.
NOTE 4 In the USA, these installation couplers are not permitted to be used where they will not be visible after
installation.
An installation coupler consists of an installation female connector and an installation male
connector for permanent connection not intended to be engaged or disengaged under load
nor to be engaged or disengaged other than during first installation or during reconfiguration
or maintenance of the wiring system in which installation couplers have been installed. This
means that installation couplers are only intended for infrequent use.
Installation couplers are not suitable for use in place of socket-outlet systems. Installation
couplers are not suitable for use in place of devices for connecting luminaires (DCLs)
according to IEC 61995 or luminaire supporting couplers (LSCs).
NOTE 5 For lower limits of in-service temperatures the necessary information is given in the manufacturer’s
installation instructions.
In locations where special conditions prevail, as in ships, vehicles and the like and in
hazardous locations, for example where explosions are liable to occur, special constructions
may be required.
NOTE 6 Particular requirements for installation couplers e.g. for. use at higher ambient temperatures, with higher
mechanical durability (e.g. metal housings), with higher fire resistance and for use in control circuits (e.g. SELV),
are under consideration.
NOTE 7 National rules may have requirements concerning the accessibility of installation couplers.
NOTE 8 Installation couplers are intended to be installed by instructed or skilled persons.
NOTE 9 National rules may specify who is allowed to carry out the connection and disconnection of installation
couplers.
