List of Voltages & Frequencies (Hz) Around the WorldThis chart includes information on voltages and frequencies found across the globe. Eachcountry is listed with the volts and frequency (also referred as Hertz or Hz and is referring tocycles per second) commonly found in each geographic area. There are approximately 40countries that use 60 Hz while the rest typically run on 50 Hz current. Single-phase power isprimarily for residential use (such as homeowners and what you would find in a hotel) while 3phase electric power provides more stable, heavy-duty power for most industrial applicationslike manufacturing plants, commercial facilities, data centers, telecom towers, hospitals, foodprocessing centers and utility power plants.Some applications use specialized high voltages (such as 4160 V or 13,400 V) but these are ona more unique basis and typically involve transformers so those are not included. Whenconsidering a backup power generator, keep in mind that the frequency can often be changedby an accomplished power generation technician or electrical contractor but you do typically seea performance loss on most generator sets when you convert from 60 hertz to 50 hertz. This ismainly because you have to slow the engine RPM down and make adjustments so the overallkW or kVA output will be lower. The opposite is also true - you can sometimes gain kW whenyou convert from 50 Hz to 60 Hz because you speed the engine RPM up.The number of wires and plugs used varies greatly by region since each country is developingand evolving their electrical grids at a different rate and over time so these are only provided asa good starting point and general guide.Single-PhaseVoltage(Volts)Frequency(Hertz)# of wires(not includingground wire)Three-PhaseVoltage (Volts)Plug TypeAbu Dhabi230 V400 V50 Hz3, 4GAfghanistan220 V380 V50 Hz4C/FAlbania230 V400 V50 Hz4C/FAlgeria230 V400 V50 Hz4C/FAmerican Samoa120 V208 V60 Hz3, 4A/B/F/IAndorra230 V400 V50 Hz3, 4C/FAngola220 V380 V50 Hz4C/FCountry
