This web page lists the nominal voltages and frequencies, power plugs, and languages used in residences and commercial sites in some 200 countries worldwide. It includes drawings of the plugs with their official designations, and with the letter designation(s) used in Electric Current Abroad-- the basic source of many similar lists found in catalogs and on the Internet. This web page summarizes over 28,100 pieces of information gleaned from 60 governmental and commercial documents. The list of sources and the authors' full database is available at internat.htm, which covers close to 300 countries.

To be used worldwide, a power supply should operate on 90-265V 47-63Hz power and have either an IEC 320 Sheet C14 (takes plug 15) or an IEC 320 Sheet C8 (takes plug 50) appliance inlet.

To be used in low-voltage countries, a power supply should operate on 90-140V 47-63Hz power, be of double-insulated construction, and have/take a plug 1 linecord.
