The National Electric Code specifies allowed wire sizes for a wide variety of situations. Local jurisdictions adopt various editions of the NEC to apply to local permits. The rules are designed to keep you and your family safe as possible and create uniform standards that all electricians are required to follow.
Section 240.4(D) of the National Electric Code is where you will find the requirements for protection of small conductors.
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.
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 .
A 20 amp circuit with #12 gauge wire will work in any event but if the nameplate recommends a 15 amp circuit then #14 gauge wire on a 15 amp circuit is sufficient. In either case you will have a double pole breaker and your equipment may not require a neutral. Always run a grounding conductor.
Use only AWG # 10 copper.
I don't understand the question, but if you want to make the line into a 20amp instead of 15amp, you just install a 20amp breaker, but remember,the wire must be 12ga wire to be connected to a 20amp breaker.

you will need 1-15 amp circuit 120 volts with 14 guage romex wire for lights / you will need 1- 20 amp circuit with 12/2 romex going to receptacle that microwave will plug into in Virginia this has to be a dedicated circuit meaning nothing else but microwave can be plugged into this receptacle. the same rules apply also to the washer and the refrigerator as the microwave. the t.v. also should have 1-20amp receptacle to plug in to but this doesn't have to be a dedicated circuit and other items can be plugged into this receptacle such as vcr's lamps etc. you did not say whether you were planning on having a 120 volt air conditioner or a 230 volt a/c but either way you will need a dedicated circuit with either 1-20amp receptacle using 12/3 romex wire or 1-30amp receptacle using 10/2 romex wire. be sure to match your breaker size to your wire size 14/2 wire size = 15amp breaker 12/2 wire size = 20amp breaker and 10/2 wire size = 30amp breaker. so if this is a new install you will need a total of 6 new breakers i can not give you the wattage or power consumption for anything but the lights which will pull about 500 watts if all on at the same time pulling about 4.3amps
No. A 20 amp breaker needs 12 gauge wire.
10 AWG.
