Voltage and frequency by country

World map depicting common frequencies for each country.

Most countries use different voltages for different electrical service types (residential, commercial, industrial). Some countries also have voltages and frequencies that vary based upon location as the grid has not been standardized. The wiring configuration - two-wire single phase (L1, N), three-wire single phase (L1, L2, N), three phase (L1, L2, L3) - can vary for the same voltage from country-to-country as well. This list is not definitive - the voltage, frequency and wiring configuration for any location should be confirmed.
