Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
Yes the voltage rating of devices is the maximum amount of voltage that it can handle. You could not use a 480 volt breaker on a 600 volt service and like wise you could not use a 208 volt rated breaker on a 480 volt service.
The outlet is connected to and protected by a breaker or fuse in a main electric panel. The outlet should be sized to the protection. Usually utility outlets in a residence are either 15 A or 20 A. If there are multiple outlets on a circuit then the total current cannot exceed the protection value of the breaker or fuse.
Answer for USA, Canada and countries running a 60 Hz supply service.Breakers are rated in amperage and by the amount of poles that they have. Your classification of a 220 breaker is described in electrical terminology as a two pole breaker.Choosing the amperage of the two pole breaker depends upon the 220 volt load that it feeds.Two pole breakers for 220 volt loads.Single pole breakers for 120 volt loads.If the service is only 120 volt then every other bus bar in the panel will be energized. If the panel is a 120/240, then every bus bar in the panel will be energized.This is how and why a 240 volt load requires a two pole breaker.To the answer, yes you an use a two pole breaker in a 120 volt service but only one side of the breaker will have voltage on it depending on where it is situated in the panel board.
Toaster, refrigerator, microwave, washing machine, mostly everything in your house.
15,000 watts at 240 volts will use 62.5 amps. Therefore you will need to use AWG #3 wire on a 100 amp breaker.
Yes the 115 volts you read is just the maximum it will handle.
You will need a multimeter to check a 220 volt breaker. You should unplug appliances that go to that particular breaker. Use the multimeter at the breaker to check the voltage. If it shows 220, then the breaker is okay. If it doesn't, then the breaker is no good.
Yes the voltage rating of devices is the maximum amount of voltage that it can handle. You could not use a 480 volt breaker on a 600 volt service and like wise you could not use a 208 volt rated breaker on a 480 volt service.
With 115 volt alternating current

your house has 220 you must use a 2 pole breaker. your wiring will change ,not a do it your selfer call someone
AWG #10 copper on a 30 amp breaker.
In North America a two pole breaker will be used in the distribution panel for a supply of 240 volts for a 240 volt load.
Toaster, refrigerator, microwave, washing machine, mostly everything in your house.
15,000 watts at 240 volts will use 62.5 amps. Therefore you will need to use AWG #3 wire on a 100 amp breaker.
Before energizing a breaker for a circuit, the circuit has to be clear of any short circuits or grounds. This can be accomplished by the use of a megger on the correct voltage setting.
