In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameterbecause the cross section is directly proportional to its strength and weight, and inversely proportional to its resistance.

Almost all characteristics of conductors, resistance, current carrying capacity etc. You can help Wikipedia by expanding it.
This is a key distinction as it makes a standardized definition of conductors based solely on their electrical characteristics. This document and its precursors were created due to a need for a standard definition of cable conductor size. The current version is Third Edition [1] Among other things, it defines a set of standard wire cross-sectional areas:. This engineering-related article is a stub. List ied International Electrotechnical Commission standards.
This page was last edited on 25 Mayat Retrieved from " https: IEC is the International Electrotechnical Commission 's 06288 standard on conductors of insulated cables.
The main problem being that not all copper has the same resistivity value, so, for example, a 4mm 2 conductor from two different suppliers may have different resistance values. 600288 using this site, you agree to the Terms of Use and Privacy Policy. The cross-sectional area is also related to the maximum current that a wire can carry safely.

This article needs additional citations for verification. However this document allows an easy reference whereby the standard lec sizes and reference to physical dimensions are maintained but given an exact meaning in terms of the electrical characteristics of a conductor. Unsourced material may be challenged and removed.
Instead this document describes conductors by their nominal size, determined by resistance rather than physical dimensions. Please help improve this article by adding citations to reliable sources. From Wikipedia, the free encyclopedia.
