Mains electricity by country - wikipedia Mains electricity by country For further information on each plug and discussion on the different voltages and frequencies used, see AC power plugs and sockets and Mains electricity. This article needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. ( January 2011 ) 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 appliances, equipment, and lighting typically found in homes and offices. ( For industrial machinery, see Industrial and multiphase power plugs and sockets. ) Some countries have different voltage levels for small vs. large appliances, and sometimes different plugs are mandated for different voltage or current levels. Voltage, frequency, and plug type vary widely, 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. Contents 1 Main reference source -- IEC World Plugs 2 Voltages 3 Plugs 3.1 Identification guide 4 Table of mains voltages, frequencies, and plugs 5 See also 6 References 7 External links Main reference source -- IEC World plugs The International Electrotechnical Commission publishes a web microsite World Plugs 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. 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 √ 2, and the peak - to - peak voltage greater by a factor of 2 √ 2. Plugs Main article : AC power plugs and sockets The lettering system used here is from World Plugs, which defines the letter names and gives a ( not always correct ) list of what plug types are used where. The Type N description is of the two variations of Brazilian plug ( Brazilian national standard NBR 14136 ) ; however, the original plug and socket is defined in IEC 60906 - 1 and has been adopted as a South African national Standard ( SANS 164 - 2 ). The Brazilian version is non-compliant with the IEC standard. Not all plugs are included in the letter system ; for example, there is no designation for the plug defined by the Thai National Standard TIS116 - 2549, though some web sites call this `` Type O ''.
