Electric Current Abroad 3
IntroductionTo assist U.S. manufacturers, exporters and individuals living or trav-
eling abroad, this publication lists the characteristics of electric current avail-able and the type of attachment plugs used in most countries. It is an updateof a similar handbook published in 1991. The tables indicate the type ofcurrent (alternating or direct current), number of phases, frequency (hertz),and voltage, as well as the stability of the frequency and the number ofwires to a commercial or residential installation. This information pertainsto domestic and commercial service only. It does not apply to special com-mercial installations involving relatively high voltage requirements or toindustrial installations.
For most countries listed here, two nominal voltages are given. Thelower voltages are used primarily for lighting and smaller appliances, whilethe higher voltages are used primarily for air conditioners, heating, andother large appliances. Travelers planning to use or ship appliances abroadshould acquaint themselves with the characteristics of the electric supplyavailable in the area in which the appliance is to be used. In some cases, atransformer may be used to correct the voltage. However, if the appliancerequires exact timing or speed and if the frequency of the foreign electricitysupply differs from the one the appliance was designed for, it is advisableto use an appliance designed for the foreign frequency since auxiliary equip-ment to change frequency is bulky and expensive. Some foreign hotelshave circuits providing approximately 120 volts which allow guests to useelectric shavers and other low-wattage U.S. appliances.
The information presented here was compiled over a period of monthsfrom a large number of sources. Consequently, there is some possibility oferrors or omissions for which the Department of Commerce cannot assumeresponsibility. In addition, this information should not be taken as final inthe case of industrial or highly specialized commercial installations. It would
4 Electric Current Abroad
be impossible for the Department to maintain complete data on every for-eign industrial installation. For special equipment for commercial use orheavy equipment for industrial use, the current characteristics for the areaof installation should be obtained from the end user.
The 1998 edition was prepared by the Trade Development unit in theInternational Trade Administration, U.S. Department of Commerce. Theinformation was compiled by John J. Bodson, industry specialist in theOffice of Energy, Infrastructure, and Machinery. Editing, desktop publish-ing, and production were done by Rebecca Krafft, of the Trade InformationDivision of the Office of Trade and Economic Analysis.
The cooperation of various government and private agencies in provid-ing data is gratefully acknowledged. Special thanks go to the U.S. Foreignand Commercial Service of the U.S. Department of Commerce and theForeign Service of the U.S. Department of State.

Key to TermsType of current—a.c. indicates alternating current; d.c. indicates directcurrent.
Frequency—Shown in number of hertz (cycles per second). Note thateven if voltages are similar, a 60-hertz U.S. clock or tape recorder willnot function properly on 50 hertz current.
Number of phases—1 and 3 are the conventional phases that may beavailable.
Nominal voltage—The term nominal voltage is used to denote thereported voltage in use in the majority of residential and commercialestablishments in the country or city. Direct current nominal voltages are110/220 and 120/240. The lower voltage is always 1/2 of the highervoltage. On a direct current installation, the lower voltage requires twowires while the higher voltage requires three wires.
Alternating current is normally distributed either through 3 phasewye (“star”) or delta (“triangle”), 4-wire secondary distribution systems.In the wye or star distribution system the nominal voltage examples are120/208, 127/220, 220/380, and 230/400. The higher voltage is 1.732(the square root of 3) times the lower voltage. In a delta or trianglesystem, 110/220 and 230/460 are examples of nominal voltages. Thehigher voltage is always double the lower voltage. The higher voltage isobtained by using 2 or 3 phase wires and the neutral wire while the lowervoltage is the voltage between the neutral wire and one phase wire. Thehigher voltage may be single or 3 phase while the lower voltage is alwayssingle phase and used primarily for lighting and for small appliances.
Type of attachment plug in use—Attachment plugs used throughout theworld come in various forms, dimensions and configurations too numer-ous to describe in this report. This report does, however, attempt to point
6 Electric Current Abroad
out the basic and most commonly used types of plugs by country. Adapt-ers may be purchased to change from the American plug type to othertypes.
Number of wires to the consumer—The number of wires which may beused by the consumer is shown. Normally, a single phase, 220/380 voltsystem or 127/220 system will have two wires if only the lower voltage isavailable (one phase wire and the neutral). It will have three wires if boththe higher and lower voltages are available (two phase wires and theneutral) and where three phase motors will be used, four wires will beavailable for the higher voltage (the three phase wires and the neutralwire).
Frequency stability—“Yes” indicates that the frequency is stable andthat service interruptions are rare.
