is the primary international standard for electrical supply voltages, providing a universal framework to harmonize power systems and equipment design globally. The current edition (2009, with 2021 amendments) defines standard nominal voltages for AC and DC systems from low to ultra-high voltage. Core Voltage Classifications

230/400 V

This is the most common range for residential and light industrial use. A significant focus of the standard was the harmonization of European voltages to the standard, a transition that was largely completed by 2003. System Type Nominal Voltage (50 Hz) Nominal Voltage (60 Hz) Three-phase, four-wire 230/400 V, 400/690 V 120/208 V, 277/480 V, 347/600 V Single-phase, three-wire Single-phase, two-wire 2. Medium and High Voltage AC Systems
