| Brazil | IEC 60906-1 | 127 V, 220 V | 60 Hz | Dual-voltage wiring is rather common for high-powered appliances, such as clothes dryers and electric showers which tend to be 220 V even in 127 V areas. Depending on the area, the exact voltage might be 115 V, 127 V, or 220 V. Since Jan 1st 2010, Brazil had converted to the IEC 60906-1 international plug which looks similar to type J but is not compatible. Since then, all devices and new buildings must comply with the new standard. In older buildings, the types A, B, C, I can still be found, but are no longer manufactured or sold in Brazil. |

| China (PRC excluding Hong Kong and Macau) | A, C, I | 220 V | 50 Hz | Most wall outlets simultaneously support Types A and I. Some outlets support Type C as well (the holes in the outlets are flat in the middle and round on the sides) so that either a Type A, a Type C or a Type I (Unearthed) plug can be used. A second outlet only type I (Earthed) is next to the unearthed multi Type A\C\I outlet. Type A outlets only fit plugs with pins of the same width—a polarized Type A plug requires an adapter. NOTE: No matter the type of plug the socket will accept, voltage in China is always 220 volts. See photo at right. |

| Hong Kong | G, M, D | 220 V | 50 Hz | Largely based on UK system. G is used in almost all products, while M is (rarely) used when required current rating is between 13~15A. Occasionally, a 'shaver' socket (similar to Type C) is found in some bathrooms that provides 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. This duo installation is not as common in HK as in the UK. There was a smaller 2 A version of type D, now obsolete. |
| Hungary | C, F | 230 V | 50 Hz | Mains voltage sometimes still popularly referred to as 220 V, although the harmonization to 230 V was completed January 1, 2003. 400 V 3-phase is also sometimes still referred to as 380 V. |

| Ireland | G, D, M, F | 230 V | 50 Hz | G Sockets and plugs standard as defined by NSAI I.S. 401 (Plug) I.S. 411 (Socket outlet). Obsolete or specialist installations may be D and M (as in the UK). Type F ("Side Earth") plugs occasionally seen in old installations probably because much of the early Irish electrical network was heavily influenced by Siemens. Formerly 220 V. ' 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 230 V socket in the same unit, or a switch to select voltage, which are sometimes labelled as 115 V and 230 V. The G type socket often has an on-off switch on the socket. 110 V centre point earthed transformers are often used for industrial portable tools. Type M plugs are permitted for applications where the power draw does not exceed 5 Amps; this power limitation allows type M sockets to be powered from domestic 10 Amp circuits and to be controlled by domestic lighting switches. |
| Isle of Man | G | 240 V | 50 Hz | --- |
| Israel | C, H, M | 230 V | 50 Hz | The standard for H plugs and sockets was recently modified to use round pins, so most modern sockets accept both type C and type H plugs. Type M sockets are used for air conditioners. Identical plugs and sockets also used in the Palestinian National Authority areas. |
| Italy | C, F, L | 230 V | 50 Hz | Common sockets have 8-shaped holes to accept both 16A and 10A version of the L plug, but in hotel rooms 10A sockets are still common. Schuko sockets are unusual, but adaptors rated up to 1500 Watt are widespread. C unearthed sockets are not used in modern installations and are very difficult to find for replacement, so there are some old installations with earthed sockets unconnected to an earthing system. Italian wall-boxes are similar to American ones, but are usually horizontally mounted, in old installation round pattrress are common. Formerly 220 V. |

| Malaysia | C, G | 240 V | 50 Hz | The official mains power voltage is AC 230 V with the tolerance of +10%,-6%. However, the supplied voltage remains at 240 V, as the supplied voltage is within the allowed tolerance. Areas that rely on private power companies, like some parts of Penang and Kedah receive a true 230 V supply. Remote villages which rely on off-grid localized diesel generators (i.e. small villages and/or isolated holiday resorts on islands too far away from the mainland to have viable underwater cabling) may receive unstable power with higher voltages, with some areas recorded to be as high as 260 V. Type C plugs are very common with audio/video equipment. Plugged into Type G outlets using widely available adapters or forced in by pushing down the shutter. The latter is widely practiced, although hazardous. Since the late 90s, dedicated Type C sockets can also be found on some power strips sold in the country for convenience given the wide proliferation of devices with Type C plugs. Type C sockets can also be found on dedicated shaver sockets in bathrooms of many hotels. Said sockets also include a Type A connector that delivers 110v of power for the convenience of tourists. Type M sockets are normally used for air conditioning (especially if the air conditioner requires a magnetic starter), heavy industrial equipment, spotlights, and less commonly, washers and clothes driers. This is because most modern washers sold in the country are also fitted with Type G plugs and are two-in-one compact units which uses the same tub for washing and drying. In the countryside, type A is also used, but rare and considered non-standard. |

| South Africa | C, M, IEC 60906-1 | 230 V | 50 Hz | Type C used for some appliances. Adapters are widely available. |
| South Korea | C, F | 220 V | 60 Hz | This is special case. Normal line voltage is 110V 60 Hz for 3 phase wiring. They make 220V by using 2 phases. In some parts of the country you will find 110V 60 Hz although most will be 220V 60 Hz. Type F is normally found in offices, airports, hotels and homes. Type C (type CEE 7/17) sockets are obsolete and manufacture was discontinued as of 2008, but examples are still found in a lot of places. In cases where a Type C socket was replaced with a Type F, the ground contact is often not connected to anything. 220 volt power is distributed by using one live pole of a three-phase 380 volt system. 110 V/60 Hz power with plugs A & B were previously used but has already been phased out. Some residents install their own step-down transformers and dedicated circuits, so that they can use 110 V appliances imported from Japan or North America. Most hotels only have 220 V outlets, but some hotels offer both 110 V (Type A or B) and 220 V (Type C or F) outlets. Switches and outlets fit American-sized boxes. |

| Sweden | C, F | 230 V | 50 Hz | Non-grounded sockets are prohibited in new installations. 400 V for some washing machines and other fixed installations. In bathroom etc. 110–115 socket can be found and used for shavers and other "bathroom tools". Formerly 220 V. |
| Switzerland | C, J | 230 V | 50 Hz | C only in the form CEE 7/16. In some very old installations, type E sockets or sockets that are compatible with type J and type E plugs are found. |
| Syria | C, E, L | 220 V | 50 Hz | --- |
| Taiwan | A, B | 110 V | 60 Hz | All outlets are Type A or Type B. When an outlet is Type B, the ground (earth) holes of the outlets are usually not connected to anything. Most appliances have Type A plugs, but computers and high-power appliances have Type B plugs. The ground prongs on Type B plugs are often cut off to make the plugs fit into Type A sockets. Different outlets (which can not accept Type A or Type B plugs) provide 220 V for air conditioners. |

| Tanzania | D, G | 230 V | 50 Hz | --- |
| Thailand | A, B, C | 220 V | 50 Hz | Although Thailand uses 220 V, type A- and type B-compatible plugs and sockets were originally adopted in Thai Industrial Standards (TIS) 166-2519 and 166-2535 in 1976 and 1992. However, type C plugs are also widely used, and a hybrid socket is almost universally found. Usually the socket is a combination of types B and C, although ungrounded type A/C hybrids are still commonly found in rural areas and older installations. Appliances with type F Schuko plugs are also common, although corresponding grounded outlets are not usually found. In 2004, TIS 166-2547 (and later, its subsequent version 166-2549) was adopted, stipulating a type C-compatible standard plug based onIEC-60906-1but with the position of the ground pin following that of NEMA 5–15 (type B). the hybrid socket is accepted as standard, with plans to phase out support for type A and type B flat pins in the future. |

| United Kingdom | G, D, M | 230 V | 50 Hz | Voltage tolerance of 230 V +10%/−6% (216.2 V to 253 V), due to be widened to 230 V ±10% (207 V to 253 V) at a date yet to be specified. Formerly 240 V in mainland Britain and 220 V in Northern Ireland. Generally Type G everywhere. A "shaver socket" (similar to Type C) is sometimes found in bathrooms that will provide low current to some other plug types. These sometimes have a ~110 V socket and a ~240 V socket in the same unit, or a switch to select voltage for a single socket. The G type socket usually has an on-off switch. IEC 60309 plugs and connectors are used in industrial and construction locations as well as for outdoor use in domestic and other business premises. Plug types D and M were used until the early 1960s but were phased out due to lack of internal fuse. They are still found in specialist applications such as theatre and TV stage lighting. |
| United States of America | A, B (IEC 60906-2) | 120 V | 60 Hz | Standardized at 120 V. Electricity suppliers aim to keep most customers supplied between 114 and 126 V most of the time. 240 V/60 Hz used for large appliances. Large residential buildings frequently have 120/208V 3-phase power, with large appliances being connected between two of the phases, giving a voltage of 208 volts. Since 1962, Type B outlets are required by code in new construction and renovation. A T-slot Type B is rated for 20 amperes for use in kitchens or other areas using large 120 V appliances. |
| Uruguay | C, F, L I | 230 V | 50 Hz | Type L is the most common in modern homes and type F is the second as a result of computer use. Neutral and live wires are reversed, as in Argentina. Type I is only found in very old installs Formerly 220 V. |
