Any small appliance or other piece of household or industrial electrical equipment which has been designed to take a small current (usually not much more than 5 Amps) from the standard household alternating current electricity supply in the US, Canada and other countries which use the same system, which is 60 Hz, 120 Volts plus or minus 10%.
The actual voltage supplied could therefore vary from 108 Volts to 132 Volts. To get the actual figures for your locality it is best to ask a local licensed electrician or your local electricity supply company.
