The standard, titled " IEC Standard Voltages ", is the definitive international reference for nominal electricity supply voltages. Developed by the International Electrotechnical Commission (IEC) , it establishes preferential values for both AC and DC systems to ensure global interoperability and safety. Core Objectives of IEC 60038 The standard serves two primary functions:
: It defines the maximum, nominal, and minimum reference values that equipment and system manufacturers must use during the design and testing phases. Standard Voltage Classifications iec 60038 standard voltages pdf 103
: The primary standard is 230/400 V . This was harmonized from older 220/380 V and 240/415 V systems, a transition completed in most of Europe by 2003. The standard, titled " IEC Standard Voltages ",
