Part 1: General requirements
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 61534-1 has been prepared by subcommittee 23A: Cable
management systems, of IEC technical committee 23: Electrical accessories.
This second edition cancels and replaces the first edition published in 2003 and constitutes a
technical revision. The main changes from the previous edition are as follows:
• updated normative references (Clause 2);
• changes to the number of samples to be tested (Subclause 5.3);
• inclusion of a short circuit test (New Clause 18);
• changes to external influences (Clause 21).

The text of this standard is based on the following documents:
FDIS Report on voting
23A/630/FDIS 23A/631/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.
A list of all the parts in the IEC 61534 series, under the general title Powertrack systems, can
be found on the IEC website.
The following difference exists in the countries indicated below:
– Table 4, first column, first line: the 10 A rated terminal should be capable of clamping 1
mm as a minimum (UK);
– Australia has specific wiring rules covering socket-outlets to be switched. In Australia,
AS/NZS 3000 contains requirements for switching devices to be used in Australian and
New Zealand electrical installations;
– 9.5: in Australia, fuses and fuse-links are not to be used.
The committee has decided that the contents of this publication will remain unchanged until
the stability 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
Particular requirements for specific types of powertrack systems will be specified in the
relevant parts 2 of IEC 61534.
For a specific type of powertrack system the requirements of Part 1 of the standard are to be
considered, together with the particular requirements of the appropriate Part 2, which will
supplement or modify some of the corresponding clauses in Part 1 to provide the complete
requirements for that type of system.
Part 1 shall apply unless supplemented or modified by an appropriate Part 2.

POWERTRACK SYSTEMS –
Part 1: General requirements
1 Scope
1.1 This part of IEC 61534 specifies general requirements and tests for powertrack (PT)
systems with a rated voltage not exceeding 277 V a.c. single phase, or 480 V a.c. two or three
phase 50 Hz/60 Hz with a rated current not exceeding 63 A. These systems are used for
distributing electricity in household, commercial and industrial premises.
1.2 Powertrack systems, according to this standard, are intended for use under the following
conditions:
– an ambient temperature in the range –5 °C to + 40 °C, the average value over a 24 h
period not exceeding 35 °C;
– a situation not subject to a source of heat likely to raise temperatures above the limits
specified above;
– an altitude not exceeding 2000 m above sea level;
– an atmosphere not subject to excessive pollution by smoke, chemical fumes, prolonged
periods of high humidity or other abnormal conditions.
In locations where special conditions prevail, as in ships, vehicles and the like and in
hazardous locations, for instance, where explosions are liable to occur, special constructions
may be necessary.
This standard does not apply to
– cable trunking systems and cable ducting systems covered by IEC 61084 [8] ;
– busbar trunking systems covered by IEC 60439-2 [5];

Part 1: General requirements
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 61534-1 has been prepared by subcommittee 23A: Cable
management systems, of IEC technical committee 23: Electrical accessories.
This second edition cancels and replaces the first edition published in 2003 and constitutes a

systems with a rated voltage not exceeding 277 V a.c. single phase, or 480 V a.c. two or three
phase 50 Hz/60 Hz with a rated current not exceeding 63 A. These systems are used for
distributing electricity in household, commercial and industrial premises.
1.2 Powertrack systems, according to this standard, are intended for use under the following
conditions:
– an ambient temperature in the range –5 °C to + 40 °C, the average value over a 24 h
period not exceeding 35 °C;
– a situation not subject to a source of heat likely to raise temperatures above the limits
specified above;
– an altitude not exceeding 2000 m above sea level;
– an atmosphere not subject to excessive pollution by smoke, chemical fumes, prolonged
periods of high humidity or other abnormal conditions.
In locations where special conditions prevail, as in ships, vehicles and the like and in
hazardous locations, for instance, where explosions are liable to occur, special constructions
may be necessary.
This standard does not apply to
– cable trunking systems and cable ducting systems covered by IEC 61084 [8] ;
– busbar trunking systems covered by IEC 60439-2 [5];
– electrical supply track systems for luminaires covered by IEC 60570 [6].
