no, load will brake at 30 not 15 as needed
Check the MFG for the amps it uses, if it is suppose to be on a regular 20amp line, then replace the breaker with a 20amp breaker. With the 30amp breaker,it will work, but if there is a surge, you could send too much power to the appliance and fry it. Most refrigerators, are just on a regular 120v household outlet. Besides a 30amp breaker must have 10ga wire, if the wire is 12ga,it can not be attached to a 30amp breaker.
Can feed two separate 15 A circuits.
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.
On a 15 amp household breaker there is no terminal on the in feed of the breaker. The breaker either plugs into the distribution panel's bus bar or it bolts to the distribution's bus bars. The feed conductor connects to the load side of the breaker at its terminal lug.
no, because it is depend on its current carrying capacity. eg-if 25amp current flowing in the ckt then 30amp breaker don't protect the ckt but if it is cross the rated capacity then breaker works.

You have a double pole breaker for 240Volt supply. The maximum current is 15 amp.

A circuit breaker of 30 amps will protect a 30 amp load . you may have a 1000 amps service it does not matter because the 30 amps breaker will open up at 30 amps therefore safe. OF COURSE THE OTHER WAY AROUND WILL NEVER WORK. Just check to make sure that the wire from the 30 amp breaker is a #10 or larger. If it was a 50 amp plug originally more that likely the wire will be a #6. As the answer above states it is safe.
The appliance works perfectly. If you did it the other way around (50amps on a 30amp breaker, you would be tripping the breaker. Think of it as a mercury thermometer. The circuit breaker is the maximum temperature and the load on that breaker is the mercury. If the load is lower than the max, everything works beautifully. If the load becomes greater than the maximum rating, then things starting popping.
50 amp breaker wired with AWG # 6 wire.
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.
Yes the wire size is larger for that size breaker but will not effect the 30 amp breaker protection of that circuit.
A 30 amp breaker is usually used for a dedicated 30 amp device. Ordinary 15 amp receptacles can not be connected to a breaker of higher trip capacity than the rating of the receptacle. The wire size for a 30 amp breaker is #10 AWG.
