INTERNATIONAL ELECTROTECHNICAL COMMISSION

POWERTRACK SYSTEMS –
Part 1: General requirements
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61534-1 has been prepared by IEC technical committee 23:
Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23/332/FDIS 23/336/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.
This standard constitutes Part 1 of the IEC 61534 series, published under the general title
Powertrack systems. The series consists of this Part 1, devoted to general requirements, and
various Parts 2, devoted to particular requirements, which are still under consideration.
---------------------- Page: 10 ----------------------
61534-1 IEC:2003 – 9 –
The committee has decided that the contents of this publication will remain unchanged until
2006-12. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
The following difference exists in the country indicated below.

INTRODUCTION
Particular requirements for specific types of powertrack systems will be specified in the
relevant Parts 2 of IEC 61534, which are still under consideration.
For a specific type of powertrack system, Part 1 is to be considered, together with
the appropriate particular requirements, which will supplement or modify some of the
corresponding clauses in Part 1 to provide the complete requirements for each type of
system. Where no such Part 2 exists, then Part 1 applies.

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.
NOTE The extension of the scope to cover d.c. and communication systems is under consideration.
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 2 000 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:
)
1
– 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]
