| 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. |

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 | 220 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.[19] |

| Malaysia | C, G, M | 240 V | 50 Hz | The official mains power voltage is AC 230 V with the tolerance of +10%,-6%.[23] 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 practised, although hazardous. Since the late 1990s, 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. |

220 V | 60 Hz | Saudi Arabia is one of the few countries in the world that still uses a dual-voltage system in different parts of the country. In an attempt to unify the low voltage system in the Kingdom, a decision was made by the Council of Ministers of Saudi Arabia in August 2010 to standardize the low voltage system as 230/400V. The decision took immediate effect for new subscribers and will be implemented in existing facilities in two phases over 25 years (10-year preparatory phase and 15-year executive phase).[31][32] |

| South Africa | C, F, M, N | 220-250 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. |
| Spain | C, F | 230 V | 50 Hz | Formerly 220 V. Also E and L in the Canary Islands. |

400 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 | In newer buildings and installation you will find only type J sockets (almost always recessed, mandatory after 2016: SEV 1011 Type 13[35]), which accept type C plugs. Relatively often, you will still find non-recessed sockets that are compatible with type J, which also accept the Europlug, but not plugs of type E, F, or E&F, since their pins are too thick (4.8mm). In some very old installations, sockets that are compatible with type E plugs are found. These non-recessed sockets will sometimes physically also accept plugs of type E, F, and E&F, but grounding will not be effective. Since 1 January 2013, it is only allowed to import or sell electronic devices with plugs with partly insulated pins, such as type C (CEE 7/16, SEV 1011 type 11) and type J (SEV 1011 type 12).[36] |
| 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. |
| Tajikistan | C, F, I | 220 V | 50 Hz | |
| Tanzania | D, G | 230 V | 50 Hz | |
| Thailand | A, B, C, TIS166-2549 | 220 V | 50 Hz | In newer buildings and installation you will find only TIS116-2549 sockets, which accept type A and B and C plugs. Relatively often, you will still find type A/C hybrid sockets that are compatible with TIS116-2549, which also accept the Europlug, but not plugs of type E, F, or E&F, since their pins are too thick (4.8mm). In some very old installations, sockets that are compatible with type A/C hybrid plugs are found. These non-grounded sockets will sometimes physically also accept plugs of type E, F, and E&F, but grounding will not be effective. Since 2008, it is only allowed to import or sell electronic devices with plugs type C (CEE 7/16) and A, B (IEC 60906-2/TIS166-2519/TIS166-2535) and TIS116-2549. |

| United Kingdom | G | 230 V | 50 Hz | Generally Type G everywhere, usually with an on-off switch for each socket. A "shaver unit" with isolation transformer accepting the UK shaver plug (BS 4573) and Europlug (and sometimes an Australian plug) is often found in bathrooms for the connection of shavers and toothbrushes only. The shaver unit may also have a type A 115 V socket. IEC 60309 plugs and connectors are used in industrial and construction locations as well as for outdoor use. Plug types D and M were phased out of general use following the introduction of BS 1363 in 1947, they are still found in specialist applications but are unlikely to be encountered by visitors. |
| United States | 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. |
