A 220 VAC breaker can be single pole or double pole depending on the application. For standard 220 VAC circuits like most household appliances, a double pole breaker is typically used. However, in certain situations where only one hot wire is needed, a single pole breaker can be used for 220 VAC circuits.
I assume you have a 30 amp two pole 220 volts breaker. Check the voltage source. If the source voltage is 220V, but out let voltage is 120 then the breaker must be faulty, a high resistance or partial open circuit could have caused the reduced voltage at the breaker outlet.
The equation that you are looking for is I = W/E. Amps = Watts / Volts.
Yes, a double pole 20 amp breaker can be used with 12-2 wire for a 240V circuit. However, make sure the device you are connecting requires 240V and not 120V. Also, consult local electrical codes and regulations to ensure compliance with safety standards.
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.

No, A double pole breaker is going to give you 220 volts. 220 Volts is too much voltage for a 110 Volt outlet to handle. == Answer== Better to pull the duplex 30a and install to single-pole 20a breakers...if one kicks out, you will know which side the problem's on. And there's no problem with running a 20a circuit over 10awg wire.

Two single-pole 30 amp breakers tied together make a two-pole 30 amp breaker. From this you can power a device that requires 220-240 volts, typically.
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.
No. If your AC is currently running on a 30 amp 2 pole breaker, then it is a 220 volt unit. You cannot substitute one 60 amp single pole breaker as you'll only be supplying 110 volts and the AC unit won't work. In fact you could damage it.
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.
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.

If the load is rated 220 or 230 or 240 volts (all the same thing), and specifies a wattage rating, that wattage rating is at the double pole voltage. You wouldn't make any adjustments to it. The load should also indicate the input current in Amps, which is used for sizing your breaker. If not, watts=amps x volts, so amps=watts/volts. For example, a 3800 Watt heater at 240v would require 15.83 amps. The breaker for this circuit would be 125 percent of that (safety factor), or 20 amps, 2 pole.
A sauna heating element is a resistive load. The equation that you are looking for is Amps = Watts/Volts = 8000/220 = 36 amps. A #8 copper conductor with an insulation rating of 90 degrees C is rated at 55 amps. This will be fed with 40 amp two pole breaker.
