IEC TR 62602:2009

Conductors of insulated cables - Data for AWG and KCMIL sizes

IEC/TR 62602:2009, which is a technical report, specifies the nominal cross-sectional areas, in the range 20 AWG to 2 000 kcmil (0,52 mm2 to 1 010 mm2), for conductors in electric power cables and cords for a wide range of types. Requirements for numbers and sizes of wires and resistance values are also included. These conductors include solid and stranded copper, aluminium and aluminium alloy conductors in cables for fixedinstallations and flexible copper conductors. This technical report is not intended to apply to conductors designed for use in cables intended for telecommunication or data transmission, winding wires or similar products. Unless indicated to the contrary in a particular clause, this technical report relates to conductors in finished cables and not to conductors made or supplied for inclusion into a cable. The annexes give supplementary information covering measurement of resistance (Annex A), temperature correction factors for resistance measurement (Annex B) and dimensional limits of circular conductors (Annex C).

Âmes des câbles isolés - Informations relatives aux sections exprimées en AWG et KCMIL

La CEI/TR 62602:2009, qui est un rapport technique, spécifie les sections nominales, dans la plage de 20 AWG à 2 000 kcmil (0,52 mm2 à 1 010 mm2) des âmes des conducteurs et des câbles électriques de puissance, dans une large gamme de spécifications. Des exigences sur le nombre et le diamètre des brins et les valeurs de résistance sont également incluses. Les âmes concernées sont les âmes massives et câblées, en cuivre, en aluminium et en alliage d'aluminium, destinées aux câbles pour installations fixes et les âmes en cuivre pour conducteurs souples. Le présent rapport technique n'a pas vocation à s'appliquer aux âmes destinées aux câbles de télécommunication ou de transmission de données, aux fils de bobinage ou à des produits similaires. Sauf indication contraire dans un article particulier, ce rapport technique porte sur les âmes des câbles terminés, et non sur les âmes seules ou fournies pour la fabrication d'un câble. Des annexes donnent des informations complémentaires sur la mesure de la résistance (Annexe A), les facteurs de correction de température à utiliser dans les mesures de résistance (Annexe B) et les limites dimensionnelles des âmes circulaires (Annexe C).

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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC/TR 62602, which is a technical report, has been prepared by IEC technical committee 20:
Electric cables.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
20/1048/DTR 20/1061/RVC
Full information on the voting for the approval of this technical report 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.

The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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
Conductors described in IEC 60228 [1] are specified in metric sizes. North America and
certain other regions at present use conductor sizes and characteristics according to the
American Wire Gauge (AWG) system, and kcmil for larger sizes. The use of these sizes is
currently prescribed across North America and elsewhere for installations by sub-national
regulations. IEC TC 20 cable product standards do not prescribe cables with AW
