What Exactly is IEC 60038?
IEC 60038: IEC standard voltages is a technical specification published by the International Electrotechnical Commission (IEC). Its primary goal is to harmonize voltage ratings for electrical systems and equipment across the globe. First issued in 1928 (originally as IEC 38), the current version is IEC 60038:2009 (with amendments up to 2017). The IEC 60038 standard defines the standard nominal
