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.
your house has 220 you must use a 2 pole breaker. your wiring will change ,not a do it your selfer call someone
Phone an electrician urgently
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.
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
Mine was 220 and I suppose they all are.
Most residential service in USA has both. In the USA 110 to 120 volts is a given and it would be very unusual not to have 220 to 240 volts. It can be easily tested at main panel with a volt meter. Or as an alternative call your power company.
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.
the 220 volt bulp in 220 volt ac current
a 220 volt, 3200 watt oven will draw under 15 amps, so yes a 2o amp breaker will work.
There is no standard Amperage for a 220 volt outlet. It all depends on the wires/conductors used to supply the outlet and the breaker that protects it. You can have an outlet with: 15 amp, 220 volt 20 amp, 220 volt And so on.....
220 volt will increase your available current capacity. for Air Conditioning window units, it allows for smaller breaker sizes.
