No, you cannot use one in place of the other.

can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.
You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
Yes.
Replacement for American Switch single pole 15 amp circuit breaker
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.

can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.
Remove the 30 amp double pole breaker and install at least one single pole 15 amp breaker. It is best if the other slot is not left open so if you have another single pole breaker of any size install it in the 2nd spot so it isn't open when you replace the cover on the panel. For your 15 amp circuit you need #14 gauge copper wire or larger with a hot, neutral, and ground. Your 30 amp circuit was probably wired with #10 gauge conductors. These will probably work on your 15 amp circuit but it may be difficult to connect #10 conductors to devices.
Answer for USA, Canada and countries running a 60 Hertz supply service.Yes, a 240v 50amp circuit can be changed to a 120v 30amp circuit. The wire for the 50 amp circuit should be a #6. This is more than ample for a 30 amp circuit. Remove the two pole 60 amp breaker and replace it with a single pole 30 and a single pole 15 amp breaker. One of the two #6 wires will be terminated on the neutral bus (if there is a white use it) and the other #6 will be terminated on the new 30 amp breaker. This will give you the required 120 volt 30 amp circuit. The new 15 amp breaker that was installed just to fill the hole from the two pole 60 amp breaker will give you a spare 15 amp circuit. I have no idea what you are trying to do, but there is no way you can change 220v 50 amp to 120v 30 amp. You can take 220 volt input in the top of your circuit breaker box. Then half of one side will be 120v and half of the other side will be 120v. You can install a 30 amp fuse. You should hire an electrician.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Use #12 wire and a 20 amp two-pole circuit breaker.
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
A double pole breaker has one pole attached to one side of your breaker panel's bus or hot leg, and another pole attached to another hot leg or bus, if it is in a residential panel (in the US) each leg of the breaker is 120 volts to ground or neutral and 240 hot leg to hot leg. The 15 amp indicates that the breaker will trip if the circuit exceeds 15 amps across the two outputs of the breaker.
