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 split-phase, with 240 volts between phases and 120 volts between either phase and neutral. Most sockets are connected to 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 source – IEC World Plugs

The International Electrotechnical Commission (IEC) 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.

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

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".

Identification guide

• Type A (NEMA 1–15 U.S. 2 pin)
  max 125 V AC, max rating 15A, (GB1002 Chinese 2 pin) max 250V AC, max rating 6A or 10A
• Type B (NEMA 5–15 U.S. 3 pin)
  max 125 V AC, max rating 15A
  and IEC standard 60906-2

India	C, D, M	IS 1293	230 V	400 V	50 Hz	(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. 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. (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. In June 2022, BIS began enforcing the standard through mandatory certification of both imported and domestic products.
Indonesia	A, C, F, G	SNI 04-3892	230 V	400 V	50 Hz	Types C and F plugs are most used. British Type G sockets are common in Riau Islands due to their close proximity to Singapore. British Type G sockets are also used for air conditioners, because most draw more current than the rating of most sockets in Indonesia. Wall sockets in most homes in North Sumatra (in cities such as in Medan and Pematangsiantar) generally accept both Type A and Type C plugs.

Ireland	G	I.S. 401	230 V	400 V	50 Hz	Type G is the only general purpose outlet type in use in Ireland. Bathrooms may have shaver sockets. These accept 2.5 amp Europlug CEE 7/16 and UK type BS4573 plugs, which used on shavers and toothbrushes. They do not accept larger Type C plugs and general purpose outlets are generally banned in bathrooms / wet areas. Some hotels may also provide a Type F (Schuko) socket as a convenience for European visitors.
Isle of Man	G		230 V	400 V	50 Hz	Self-governing British crown dependency, but generally uses UK technical standards.
Israel	C, H		230 V	400 V	50 Hz
Italy	C F, L	CEI 23-34 CEI 23-50	230 V	400 V	50 Hz	Type L uses two gauges of plug and socket. The 10 Amp version has pin spacing that is compatible with Europlug. The 16 Amp version uses wider pin spacing and larger pins. Hybrid outlets that accept both types are common and some also accept type F. NB: 16 Amp Type C plugs, such as CEE 7/17 commonly found on hairdryers, will not fit Type L outlets and need an adapter, or should be used with a Type F or hybrid Type L/F outlet.

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 regions 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."
