The receptacle is what you plug your tool/appliance into. Receptacles have specific voltage and amperage ratings. There are 120 volt or 230/240 volt receptacles; some have a GFCI (Ground Fault Circuit Interrupter) built-in, some do not. Generators that have a voltage switch can switch from 120/240 volts, but there are separate outlets for each.
