IEC 60949 is an international standard for electrical cables, specifically for "Polyvinyl chloride insulated cables of rated voltages up to and including 450/750 V". This standard outlines the requirements for the design, construction, and testing of PVC-insulated cables used in a wide range of applications, including power distribution, industrial, and commercial installations. This standard outlines the requirements for the design,

The standard calculates the permissible short-circuit current ( ) or the required conductor cross-sectional area ( ) using a specific thermodynamic formula. The fundamental equation is expressed as:
