Mains electricity by country

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 most sockets are attached to a 120 V supply, but there is a 240 V supply available for large appliances. Often different sockets are mandated for different voltage or current levels.

Nominal frequency and voltage by country, for portable appliances.

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 source – IEC World Plugs

The International Electrotechnical Commission publishes a web microsite World Plugs[1] 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[2] clearly states the voltage as 230 V, and the official travel website says "electric power supply is 220 volts in all regions."[3]

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 √2, and the peak-to-peak voltage greater by a factor of 2√2.

Plugs

Types of power plugs and sockets used by country, for portable appliances.

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.[4] World Plugs 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 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".

1. "C" may indicate that buildings have three-pin sockets compatible with Europlugs, which also work with other plug types or that buildings have some or all two-pin European style sockets, similar to CEE 7/1, or that use of an adaptor is common practice. Not all two-pin European plugs are compatible with all two-pin European sockets; see AC power plugs and sockets § Compatibility.

Until 2003, as a first stage, power supply companies in countries with a 220/380 V network should lead the voltage to The value of 230/400 V (GOST 29322-92 (IEC 38-83) Standard voltage%). Electricity supply companies in countries with 240/415 V network should also bring this voltage to the value 230/400 V (GOST 29322-92 (IEC 38-83) Standard voltage%). After 2003, the range of 230/400 V ± 10% should be reached. Then, the issue of reducing the limits will be considered."
