For your typical residential application American Wire Gauge 12, or 12 AWG is rated for 20 amps.
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
The amperage rating of any wire or conductor is determined by its size or gauge. It has nothing to do with whether it is a two, three or four conductor wire. For example, in basic residential wiring, a 14 gauge wire is rated at 15 amps, a 12 gauge wire is rated at 20 amps, a # 10 is rated for 30A and so forth.
A. It's 240 volts & B. Wire size is a function of amperage. 12-gauge wire is used with 20 amperes or less. So, 12-gauge wire can be used with 120V/20A or 240V/20A. Keep in mind though that 240V in the U.S. has 2 live 120V lines so if you encounter a white wire, it's probably an unmarked live & should be repainted as black or better yet, red (to indicate the 2nd live wire).
The minimum amperage for a 220-volt outlet is typically 15 amps for residential settings, but it can vary depending on the specific electrical needs of the equipment or appliances that will be connected to the outlet. It is important to consult with a qualified electrician to determine the appropriate amperage for your specific setup.
12-2 (#12-2 conductor) wire doesn't "pull" 20 amps. However, it's ampacity rating is that of 20 amps. #12 copper wire is rated for a total load of 20 amps. So, always use a 20 amp breaker with it.
An 18 gauge wire can handle a maximum amperage of approximately 16.5 amps at 12 volts.

The recommended gauge of wire to use for a 12 or 14 gauge wire is typically 10 gauge wire.

You need to know the amperage to size the wire. For 220 V at 20 A you would need 12 AWG. At 220 V at 30 A 10 AWG.
The main difference between 14 gauge and 12 gauge wire is their thickness. 12 gauge wire is thicker than 14 gauge wire, meaning it can carry more electrical current without overheating. This makes 12 gauge wire suitable for higher power applications compared to 14 gauge wire.
The maximum distance a 12 gauge electrical wire can run depends on the voltage and amperage of the circuit it is serving. In a typical residential circuit with 120 volts and 20 amperes, a 12 gauge wire can run up to 60 feet before voltage drop and overheating become concerns. It is always best to consult local electrical codes and standards for specific guidance on wire length limitations.
wire gauge is used to determine the size of the wire to be installed based on the amperage draw of whatever is being hooked up on the receiving end. ie 14 gauge is for a 15 amp circuit, 12 gauge is for a 20 amp circuit, 10 gauge 30 amp etc. to get specific amp draw ratings on a particular gauge of wire look at a current National Electric code book or ugly book.
Yes, the smaller gauge number, the larger the wire is.
