Mains electricity by country

For broader coverage of this topic, see Mains electricity.

Frequency and voltage supplied to most premises 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, a unique split-phase system is used to supply to most premises that works by center tapping a 240 volts transformer. This system is able to concurrently provide 240 volts and 120 volts. Consequently, this allows homeowners to wire up both 240 V and 120 V circuits as they wish (as regulated by local building codes). Most sockets are connected to 120 V for the use of small appliances and electronic devices, while larger appliances such as dryers, electric ovens, ranges and EV chargers use dedicated 240 V sockets. Different sockets are mandated for different voltage or maximum 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 source - IEC World Plugs

[edit]

The International Electrotechnical Commission (IEC) 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.

## Voltages

[edit]

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 {\displaystyle {\sqrt {2}}} , and the peak-to-peak voltage greater by a factor of  2 2 . {\displaystyle 2{\sqrt {2}}.}

## Plugs

Main article: AC power plugs and sockets

Types of power plugs and sockets used by country for portable appliances.
A •  B, A •  C •  D, M •  E, C •  F, C •  G •  H, C •  I •  J, C •  K, C •  L, C •  N, C

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.[2] 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".

### Identification guide

[edit]

* Type A (NEMA 1–15 U.S. 2 pin)
max 125 V AC, max rating 15 A, (GB1002 Chinese 2 pin) max 250 V AC, max rating 6 A or 10 A

* Type B (NEMA 5–15 U.S. 3 pin)
max 125 V AC, max rating 15 A
and IEC standard 60906-2

* Type C (CEE 7/16 Europlug)

* CEE 7/17 2-pin plug

* Type D (BS 546 5 A)

* Type E (French) CEE 7/6 plug & CEE 7/5 socket, 16 A

* Type F ("Schuko") CEE 7/4 plug & CEE 7/3 socket, 16 A

* CEE 7/7 plug, (combines earthing methods of Type E & Type F)

* Type G (BS 1363 UK)

* Type H (SI 32 Israel)

* Type I (Australian AS/NZS 3112); Argentinian version has reversed polarity compared to Chinese and Australian versions

* Type J (SN 441011 Switzerland), 10 A

* Type K (SRAF 1962/DB Denmark)

* Type L (CEI 23-50)

* Type M (15 A BS 546)

* Type N (NBR 14136, Brazil and SANS 164-2, South Africa)

* Thai TIS 166-2549 mains plug, often known as Type O[3]

* So-called "universal socket" which meets no standard[4] but accepts a number of different plug types (criticized as non-compliant and unsafe)[5][6]

(1) It is worth noting that the combination of a Type C, E or F plug with a Type D socket may often be workable; but it is unsafe to use.[36][37] Type C, E & F plugs/sockets are not accepted in the IS 1293 standard. The standard uses Type D sockets for 6 A current and Type M sockets for 16 A current.[38][39][40][41]

(2) From August 2015, the Bureau of Indian Standards (BIS) began clamping down on the sale in the country of imported products with the Type C/E/F plug by pushing manufacturers and importers to comply with the IS 1293 standard.[42] In June 2022, BIS began enforcing the standard through mandatory certification of both imported and domestic products.[43]

## Notes

[edit]

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.
