Nominal utility voltage at the service to a house is 120/240 volts, with three wires. 240 volts is measured across the two "line" conductors, and 120 volts is measured across either line conductor and the neutral. The range of tolerable voltage is within 5% above and below the nominal voltage.

The voltages of 220 - 240 and 110 - 120 volts all fall within the normal voltage range of a utility company's mandate. They are what is known as a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. e.g. Wattage load of 2400. Amps = watts/volts. 2400/220V = 10.9 amps. 2400/240V = 10 amps. Amps = watts/volts. 2400/110V = 21.8 amps. 2400/120V = 20 amps. On a constant resistance as the voltage goes lower, the current goes higher and vise versa as the voltage goes higher, the current goes lower.
In the US a general purpose receptacle outlet would be 120 volts; England 240 volts, France 115 volts, Libya 127 volts, Okinawa 100 volts, Tanzania 230 volts . . .; all depends on where your house is.
Answer for USA, Canada and countries running a 60 Hertz supply service.Need to know the voltage of the outlet plug. On a 120 volts outlet there is one hot terminal and on a 240 volt outlet there are two hot terminals.
A standard two prong outlet in the US carries 110 volts. Actual voltage in your area may vary from below 100 to 140 volts, but these extremes are unusual. Most of the rest of the Americas (North and South) uses the same standard. In Europe, the standard voltage in a "two prong outlet" is 220 to 240 volts. In the US, this voltage is reserved almost exclusively for use by stoves and ovens in the home.
Normal home electrical service in most residential areas is provided at 120/240 volts. A 400 amp service would still typically be delivered at this voltage. The 400 amp rating indicates the maximum current capacity that the service can handle.
Seeing that the question comes from North America the most common duplex receptacle has 110 - 120 volts potential to ground. The second most common potential difference is 220 - 240 volts. These voltages are obtained from a 120/240 volt system common to home connections from the local utility companies.
A duplex outlet is 115vac.

All over Europe we got 230 volts AC and 50 Hz. That is where Germany is situated.
An outlet with too many volts in it or a short.
The standard voltage in Canada is 110 volts, which is the normal amount that runs electrical items like computers and radios. 220 volts is required to operate heavy appliances like stoves and electical washers and dryers. Jim B. Toronto,.

150 or 240 in the UK
240 volts
A dryer outlet typically has a voltage of 240 volts. When working with a dryer outlet, it is important to turn off the power at the circuit breaker, use insulated tools, wear protective gear such as gloves and goggles, and avoid touching any exposed wires to prevent electric shock.
