This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life. The NEC covers branch circuits in Article 310. Your answer is in there.
A #10 copper conductor with a insulation rating of 90 degrees is rated at 30 amps.
The term "double pole" usually means a breaker with 2 handles that attaches in the space as a normal single pole breaker. If this is what you mean, no, you cannot. There is no potential, or voltage, between the wire terminals. If by "double pole" you mean what is usually called a 2-pole breaker, which is a breaker with 2 handles that attaches in the space of 2 single pole breakers, then yes, you can use this breaker and 12/2 wire to produce a 220v circuit.
The minimum size wire a 20 amp breaker needs to be connected to is a #12 wire. The 15 is probably connected to a #14 right now which is only rated for 15 amps. Remember the breaker is sized to the wires ampacity not the load .
well, the easy answer is, black wire to one pole of the breaker, white wire to the neutral bus with all the other white wires, bare wire to the ground bus with all the other bare (or green) wires. BUT the breaker must be 20 amps or less for residential outlets and you much match the wire size to the breaker, #14 for 15 amp breaker, #12 for a 20 amp breaker AND if there is only going to be one outlet, if it is a 20 amp circuit, the outlet has to be rated for 20 amps. Yes, but why would you want to? It is unclear to anybody else what you are doing and therefore a hazard. Do it right. Use a single pole breaker designed for 110V.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
If the 12,000 BTU A/C only requires 20 amps to run then yes you can use the same 12 gauge wire but you cannot change it to a 15 amp breaker. You will need to install a 20 amp double pole breaker. If it requires more than 20 amps you will have to replace the wiring and breaker.
Take out the double pole breaker, place the white wire on the grounding bar along with the ground wire, install singe pole breaker(size needed) attach black wire onto new breaker and you now have 110 line.

can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
10/3 wire with 30 amp double pole breaker from panel box to water heater.
The minimum size wire a 20 amp breaker needs to be connected to is a #12 wire. The 15 is probably connected to a #14 right now which is only rated for 15 amps. Remember the breaker is sized to the wires ampacity not the load .
50 amp breaker wired with AWG # 6 wire.
No, the wire will overheat.
A double pole 30 amp breaker can pass 30 amps per pole, therefore #10 wire should be used.
well, the easy answer is, black wire to one pole of the breaker, white wire to the neutral bus with all the other white wires, bare wire to the ground bus with all the other bare (or green) wires. BUT the breaker must be 20 amps or less for residential outlets and you much match the wire size to the breaker, #14 for 15 amp breaker, #12 for a 20 amp breaker AND if there is only going to be one outlet, if it is a 20 amp circuit, the outlet has to be rated for 20 amps.

Use #12 wire and a 20 amp two-pole circuit breaker.
A single pole circuit breaker can protect one hot wire to a given load where as a two pole circuit breaker can protect two hot wires to a given load. In the North American system this would equate to 120 volts on a single pole circuit breaker and 240 volts on a two pole circuit breaker.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
