This is a comprehensive guide to electrical voltage by country/region, detailing single-phase and three-phase voltages, frequencies, and plug types. The table lists the standard mains voltage for each country, with single-phase voltages typically ranging from 220 to 240 volts (50 or 60 Hz) and three-phase systems at 380 to 415 volts. It also specifies the plug types used in each country.
Looking at the table, you’ll find that most countries adhere to uniform power voltage standards. However, some African, Asian, and South American countries exhibit multiple voltage and plug types, with voltage and plug types varying by region.
To quickly find a country in the table, use CTRL + F.
