List of countries with mains power plugs, voltages and frequencies

Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices. (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some countries have more than one voltage available. For example, in North America the supply to most premises is 2 phase plus neutral, with 240 volts between the phases and 120 volts between either of the phases and neutral. Most sockets are attached to the latter 120 V and neutral. By connecting across the phases, 240 V is available for large appliances. Often different sockets are mandated for different voltage or current levels.

Voltage, frequency, and plug type vary, but large regions may use common standards. Physical compatibility of receptacles may not ensure compatibility of voltage, frequency, or connection to earth (ground), including plugs and cords. In some areas, older standards may still exist. Foreign enclaves, extraterritorial government installations, or buildings frequented by tourists may support plugs not otherwise used in a country, for the convenience of travellers.

Main reference sourceIEC World Plugs

The International Electrotechnical Commission (IEC) publishes a web microsite ''World Plugs''World Plugs
International Electrotechnical Commission (IEC). Retrieved on 2018-06-05. which provides the main source for this page, except where other sources are indicated. ''World Plugs'' includes some history, a description of plug types, and a list of countries giving the type(s) used and the mains voltage and frequency.

Although useful for quick reference, especially for travellers, ''IEC World Plugs'' may not be regarded as totally accurate, as illustrated by the examples in the plugs section below, and errors may exist, such as Indonesia being listed as using both 220 V and 110 V when the Indonesian Standard ''SPLN 1'' clearly states the voltage as 230 V, and the official travel website says "electric power supply is 220 volts in all regions."

Voltages

Voltages in this article are the nominal single-phase supply voltages, or split-phase supply voltages. Three-phase and industrial loads may have other voltages.

All voltages are root mean square voltage; the peak AC voltage is greater by a factor of , and the peak-to-peak voltage greater by a factor of .

Plugs

The system of plug types using a single letter (from A to N) used here is from ''World Plugs'', which defines the plug type letters in terms of a general description, without making reference to specific standards. Where a plug does not have a specific letter code assigned to it, then it may be defined by the style sheet number listed in IEC TR 60083. Not all plugs are included in the letter system; for example, there is no designation for the plugs defined by the Thai National Standard ''TIS 116-2549'', though some web sites refer to the three-pin plug described in that standard as "Type O".
