ELECTRIC POWER AROUND THE WORLD
The table below summarizes information on the electrical systems in use in most countries of the world.
The voltages listed here are the “nominal” figures reported to be in use at most residential or commercial sites in the country or area named. Most electrical power systems are prone to slight variations in voltage due to demand or other factors. Most appliances are built to tolerate current a certain percentage above or below the rated voltage to accommodate these differences. However, severe variations in current can damage electrical equipment.
The electric power frequency is shown in the number of hertz (cycles per second). Even if voltages are similar, a 60-hertz clock or tape recorder will not function properly on 50 hertz current. All systems described here use alternating current (AC) except in the few instances where direct current (DC) is noted.
The plug types listed indicate all types known to be in use in that country. Not all areas of a country may use all types of plugs listed for that country, since there may be regional differences based on the power system in a certain area.
Finally, I've only included information that is likely to be relevant for travelers. Just about everywhere listed here has higher voltage lines available for heavy duty appliances (not to mention commercial or industrial applications). While this would be relevant for those moving to another country, I'm assuming most travelers will leave their clothes dryers, air conditioners and arc welders at home!
