From Wikipedia, the free encyclopedia

Line voltage is often also called mains voltage, power supply voltage, supply voltage, or system voltage. The term “mains” usually refers to the general purpose alternating current (AC) electrical power supply (as in “I've connected the appliance to the mains”). The term is not usually used in the United States and Canada. In the United States, mains power has a variety of names. It is often called household power, household electricity, domestic power, wall power, line power, AC power, or grid power.

This is a list of countries and territories, with the plugs, voltages and frequencies they use for providing electrical power to small appliances and some major appliances. For definitions of terms and further information on each plug, see Domestic AC power plugs and sockets.

Most places on the list are autonomous countries; however some territories that do things very differently from the countries they belong to (such as Hong Kong) are listed separately.

The lettering system, which is believed to have originated from a U.S. government document<ref name=ECA>Electric current abroad, a US government document that defines the letter names and gives a (not always correct) list of what plug types are used where</ref>, although useful for quick reference is a bit ambiguous in some areas. A plug and socket that are classified here under the same letter will usually mate, but there is no guarantee of this.

Note: Most European countries are gradually moving towards a 230 volt standard.

Dual-voltage wiring is rather common in Brazil - high-powered appliances, such as clothes dryers, tend to be 220 V even in 110 V areas. Note also that depending on the area, the exact voltage might be 110 V, 115 V, 127 V, 130 V, 220 V or 240 V. Also note that by 2009, Brazil will be converting to the IEC 60906-1 international plug which is similar to type J.

Many buildings wired for dual voltage but 120 V is the norm in single voltage installations. Type A outlets used for retrofit only, type B now required by code in new construction and renovation.

The A and C types are sometimes together (flat with rounder ends) so that an A or C types can be used. The I type is next to the A C type. It should be noted that C type are plugs are rarely seen in appliance. The A type pictured shows polarized flat pins, one flat pin is larger then the other. The PR China flat pins are the same size. A polarized "A" plug will not fit into a PR China A type outlet without an adapter because of this. Use of G is probably influenced by Hong Kong.

M is still official when required current rating is between 13~15A 220 V 50 Hz Largely based on UK system. A 'shaver' socket (similar to Type C) is sometimes found in bathrooms that will provide low current to some other plug types. These almost always have a 110 V socket and a 220 V socket in the same unit, or a switch to select voltage, which are sometimes labelled as 110 V and 220 V. Not so common in HK as in the UK.

'Shaver socket' sometimes seen (as in the UK); Type F ("Side Earth") plugs occasionally seen in old houses probably because much of the early Irish electrical network was built with assistance from Siemens. Isle of Man C, G 240 V 50 Hz Israel C, H, M 230 V 50 Hz Most modern sockets accept both type C and type H plugs. Type M sockets are used for air conditioners.

Many private power plants are still 60 Hz. Types A & B are used for 110 V; C & F are used for 230/240 V. It is highly recommended to verify the voltage with a tester before plugging appliances in, no matter the outlet! (As of early 2005 there is no centralized power company in Liberia. All electricity is privately generated.) Libya D 127 V 50 Hz Barce, Benghazi, Derna, Sebha & Tobruk 230 V.

Type C plugs are very common with AV equipments and other low-powered equipments. Plugged using widely-available adapters or forced into type G sockets by pushing down the shutter. The latter is widely practised, although hazardous.

Voltage can vary 110 to 135 depending on local transformer. Split phase (often incorrectly termed two phase) is commonly available and local electricians are apt to wire both to a type A/B socket to give 240 V for air conditioning or washing machine/dryers: beware, there is never a warning!
