The numbers of older IEC standards were converted in 1997 by adding; for example IEC 27 became IEC. IEC standards often have multiple subpart documents; only the main title for the standard is listed here. IEC Letter symbols to be used in electrical technology. IEC International standard of resistance for copper. The authors thank the International Electrotechnical Commission (IEC) for permission to reproduce information from its International Standard: IEC ed. 5. 0 (2007) IEC Am2 (2005) IEC ed. 4. 0 (2006) IEC As for IEC, it relates to the a. c. lowvoltage circuit breakers MCBs we find in our homes, schools, shops, and offices electrical distribution switchboards. The standard states that the top rated current is 125A, while the lowest is 6A and maximum value of rated shortcircuit capacity (Icn) is 25kA.
