Country overview connector types, line voltages and frequencies

This is a country overview of the types of mains plugs , mains voltages and frequencies that are used for connection to the lowest level of the low-voltage networks (also known as the lighting network ) for electrical devices and lights . Alternating current is used for power supply in all countries .

Power plug types

Plug (see list)

The letters used do not correspond to a standard designation. The types A – L listed below were arbitrarily assigned in a publication by the US Department of Commerce in 1998 and have since been used worldwide in comparisons, including by the IEC , which added the types M and N to the list:

• 

  Connector type A
  ( NEMA  1-15, 2-pin)

• 

  Connector type B
  (NEMA 5-15, 3-pin)

Supply voltage tolerances

Line voltage and frequency

Until the 1960s, tolerances of (−20… + 10)% were common for the supply voltage . In the case of partially contradicting information such as 220 volts with (−20 ... + 10)%, 230 volts with ± 10% and 240 volts with (−10 ... + 5)%, it is therefore the same nominal voltage for which the energy supply companies (EVU) as a supplier guarantee different tolerances.

Distribution system

For most users in the tourist area, this column is purely informative. It indicates the option of being able to offer different voltages through different interconnections. In most cases, the low value is understood to mean the normal mains voltage for small consumers. The abbreviations in the table mean:

1. Y = three-phase system . A mains voltage specification such as 230 V is the single-phase voltage between an outer conductor and the star point for consumers with lower power. For three-phase devices, the voltage between the outer conductors is ≈ 1.73 times. For example 230 V •  ≈ 400 V. ${\displaystyle {\sqrt {3}}}$ ${\displaystyle {\sqrt {3}}}$
2. B = single-phase three-wire system . A mains voltage specification such as 110 V means a single-phase voltage for consumers with lower power. For larger consumers, the voltage, which is also single-phase, is double. For example 110 V • 2 = 220 V.
3. M = single phase system . In this distribution system there is only one mains voltage.

Country list

Most of the entries in the list below concern independent states. However, there are some areas where things are handled differently than in the respective mother countries, e.g. B. Hong Kong , these countries are listed separately.

There are still a few old sockets that have not been converted that are designed so that both type A and type C can be plugged in. Side-by-side cabling of both mains voltages is not uncommon, electricity consumers with higher power requirements such as washing machines are more likely to be connected to 220 V - even in areas where 110 V predominates. It should be noted that, depending on the region, the exact line voltage can also be 110 V, 115 V, 127 V, 130 V, 220 V or 240 V.

Costa Rica	A, B	120	60	B.
Denmark	C, K	230	50	Y
Germany	C, F	230	50	Y	Type F (" Schuko ", short for "protective contact") is the standard. Type C ( Euro plug ) is common for devices with protective insulation and low power consumption. Type C sockets are rarer, they exist in space-saving multiple sockets and in older installations. Especially in the new federal states there are sockets with the protection class “classic zeroing ” in old installations , the neutral conductor also serves as a protective conductor. Plugs available in Germany (on devices) with a protective conductor are usually of type E + F. In parts of the federal state of Berlin there are still grid areas with 3 × 230 V, where single-phase consumers for 230 V are connected between two external conductors . In hotels, electrically isolated razor sockets are also widespread, which can also accept British and American plugs.

Israel	C, H	230	50	Y
Italy San Marino Vatican City	L, C, (F, E)	230	50	Y	The Italian L socket is available in two versions in older buildings: the larger 16 amp socket with wider contact spacing and larger contact diameter (only compatible with 16A L plug), and the smaller 10 amp version, the accepts both earthed 10A-L plugs and Euro plug C. In new buildings, a combination socket for 16A and 10A L plugs is common and allows three sockets (or a light switch and two sockets) in the place of an Italian standard flush-mounted socket or two L sockets in the same place of a Schuko socket. A variant that can accept both 16A and 10A-L plugs (center pin earth) and Euro plugs or alternatively Schuko plugs and (less often also French E) is used in new installations at an additional cost. Pure Schuko sockets (CEE 7/7) are not available as they are not compatible with most earthed Italian household appliances. BTicino “Magic” has almost disappeared due to its incompatibility with all other connectors.
Jamaica	A, B	110	50
Japan	A, B	100	50 and 60	Y, B	East Japan 50 Hz ( Tokyo , Kawasaki , Sapporo , Yokohama , and Sendai ); West Japan 60 Hz ( Osaka , Kyōto , Nagoya , Hiroshima ).

It is highly recommended that you check the line voltage with a tester, no matter what the outlet looks like. (As of 2005 there was no central electricity supplier in Liberia. Electricity was generated privately.)

Type C sockets are still very common in residential buildings, as type F was only required in kitchens, bathrooms and outdoor areas until 1997. Residential houses have been connected in a single phase for a long time, but now a three-phase connection is also becoming more and more common for residential buildings.

Sweden	C, F	230	50	Y
Switzerland	C, J	230	50	Y	Type C only in the version Euro plug (CEE 7/16, not earthed, pin thickness 4 mm). In newer buildings and installations there are only type J sockets (mostly with a recessed socket, mandatory after 2016: SEV 1011 Type 13), which accept the Euro plug and the grounded type J plug, but not the French CEE 7/17. However, there are still relatively often flat, non-recessed sockets of the type J, which also accept the Euro plug, but not the French type E or C, or the German type F plug, because their pins are too thick (4.8 Millimeter). In very old installations, one can find non-recessed type C sockets or those that accept type E plugs. These non-recessed plugs also accept plugs of types E, F, or E&F, but the grounding does not work! Since January 1, 2013, only partially insulated plugs (SEV 1011, type 11 [type C, ungrounded] and type 12 [type J]) may be put into circulation in Switzerland.

Turkmenistan	B, F	220	50	Y
Uganda	G	240	50	Y
Ukraine	C, F	230	50	Y	House connections are usually only single-phase, the electrical installations usually do not have a protective conductor. In older installations in particular, sockets for plugs with a smaller pin diameter ( Gost 7396 system) than with the type C contour plug are used. In some places 110 V sockets can still be found.
Hungary	C, F	230	50	Y
Uruguay	C, F, I, L	220	50		Type F is becoming increasingly common as a result of computer usage. External conductor and neutral conductor exchanged as in Argentina.
Uzbekistan	C, F, I	220	50	Y	No standard in hotels (in newer hotels type F and / or G are found, depending on the hotel)
Vanuatu	I.	220	50		Type E is rarely found in old French installations like in France.
Venezuela	A, B	120	60	Y
United Arab Emirates	C, D, G	220	50
United States	A, B	120	60	Y, B	240 V for air conditioners or electric tumble dryers, plug similar to type I. New 240 V systems officially according to NEMA type 14-50R up to 50 A, and 14-30R up to 30 A. Three -phase power generation and high-voltage network, only small consumers supplied via single-phase three-wire network .
United Kingdom	G (D and M can be found in very old installations and for special devices)	230	50	Y, B	A shaver socket is sometimes found in bathrooms and will accept small consumers of electricity with British BS-4573 plugs and other two-pin plug types. It almost always combines a 110 V and a 220 V connection option in the same socket or a switch with which the mains voltage can be selected. The type G socket often has an on / off switch. A two-pin plug of the BS 4573 standard is common for shavers and chargers for electric toothbrushes, it corresponds to the 5 A version of the type D and looks very similar to the Euro plug. Therefore, adapters from type G to type D are widespread and easily available, which also accept the euro plug. Tourists should not confuse this with an adapter for a Schuko plug, as this would not contact the protective conductor, which could be life-threatening.
Vietnam	A, C, G	127 and 220	50	Y	Should be standardized to 220 V. Type G is found in newer hotels, especially those built by Hong Kong and Singapore firms.
