This is the most common range for residential and commercial use. : It provides a specific list of values

: Includes a variety of North American and international standards, such as 120/208 V , 120/240 V (split-phase), and 277/480 V . High Power Industrial : Uses 400/690 V and up to 1,000 V. 2. Traction Systems (AC and DC) : Includes a variety of North American and

: 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

: 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 ", 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:
