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.

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:
– 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]
