Answer for UK, Europe and countries running a 50 Hz supply service.
There are quite a few appliances that use a 240V line. Air conditioners, fridges, washers and dryers all use the 240V line.
Answer for Canada, USA and countries running a 60 Hz supply service.
In North America only the larger appliances use 240 volts. The hot water tank, stove, range top, baseboard heating and clothes dryer are the main appliances that use the higher voltage.
Any appliances that draw over 1500 watts should be on a 20 amp circuit.
The number of 20 amp branch circuits required for appliances depends on the total electrical load of the appliances. A general rule is to have one 20 amp circuit for every 600-700 square feet of living space. It is best to consult with an electrician to determine the specific requirements for your appliances.
Typically, a kitchen requires two 20 amp small appliance circuits. These circuits are designated for powering countertop electrical outlets in the kitchen and help prevent overloading when multiple appliances are used simultaneously.
In the United States, there isn't a hard limit on how many 20 amp circuits that can be run on a 50 amp supply. This is because in most cases, especially in homes, we don't load most circuits with more than an amp or 2, even when they are protected by a 20 amp breaker. From a practical perspective you probably have a limited number of slots for breakers in your service or supply panel.
The choice between a 20 amp GFCI and a 15 amp GFCI depends on the ampacity of the circuit you are protecting. A 20 amp GFCI can handle up to 20 amps of current and is typically used for circuits rated at 20 amps or less. A 15 amp GFCI is suitable for circuits rated up to 15 amps. It is important to match the GFCI to the ampacity of the circuit to ensure proper protection.

The main difference between a 20 amp and a 15 amp GFCI outlet is the amount of electrical current they can handle. A 20 amp outlet is designed to handle higher electrical loads than a 15 amp outlet, making it suitable for appliances and devices that require more power.

The main difference between a 15 amp and a 20 amp GFCI is the amount of electrical current they can handle. A 15 amp GFCI is designed for circuits with a maximum capacity of 15 amps, while a 20 amp GFCI is designed for circuits with a maximum capacity of 20 amps. This means that a 20 amp GFCI can handle higher power loads than a 15 amp GFCI.
AWG 12/2 wire on a 20 amp breaker. There must be 2 kitchen outlet circuits and each circuit must be protected with a GFCI outlet. Each of these items must be on it's own dedicated 20 amp circuit. Garbage disposal, dishwasher, microwave, refrigerator. This will require 6 dedicated 120 volt 20 amp circuits plus a 240 volt 60 amp circuit for the range.
For outlets, it is recommended to use 12-gauge wire for 20-amp circuits and 14-gauge wire for 15-amp circuits.
In a 20 amp wire size chart, you can find information about the appropriate wire gauge or size to use for circuits that require a 20 amp electrical current. This chart will provide guidance on the recommended wire size based on the distance the wire needs to run and the type of material it is made of.

It is important to match the outlet amperage with the circuit capacity to ensure safe and proper functioning.
Household circuits come in two flavors, 15 amp and 20 amp. Check the circuit breaker or fuse in your panel to see which one your outlet is wired to. If the outlet is on a 15 amp circuit, you could only run one, but if you have a 20 amp circuit, you could get away with two, assuming there are no other appliances plugged into the same circuit. The electrical code says circuits should be loaded to no more than 80% of the breaker's rating. for a 20 amp breaker, that works out to 16 amps. Your two lamps would draw 16.6 amps, so you would be right at the limit.
