The NEC table 310.16 does not go that small. If there is a code requirement in your location, you must follow it.
Otherwise, a recommendation I found suggests 11A for short in-chassis wiring, and no more than 1.5A for longer power distribution wiring.
With wire this small, your current will probably be limited more by maximum permissible voltage-drop than a safety rating.
The electrical code does not go smaller than a #14 wire which is rated at 15 amps.
....
Reading the ARRL Handbook, 1970 version, page 526, the Copper Wire Table,
indicates that a single conductor of 18AGW wire in open air can handle 16A, but bundled or in conduit 10A should be the maximum.
Remember, safety is YOUR responsibility.
The electrical code book does not supply amperages for wires below a #14 wire. A # 14 wire is protedted by a 15 amp breaker. Smaller size wires need their own protection depending on what the load amperage is.
I cannot find 22 gauge wire on any chart in the NEC. That must be a speaker or signal wire for which ampacity is not usually a consideration.
This is speaker wire and it can carry no more than .92 amps.
20 gauge copper wire can carry 1.46 amps. Insulated copper wire can carry 6.5 amps. This is assuming a short run of 25' or less.
12 gauge
Yes you can as long as it is feed off of a 20 amp circuit in at least #12 gauge wire.
If you have 100 amp wire, you can use it for a 60 amp circuit, or for any circuit of 100 amps or less. But if you have a 60 amp circuit, 60 amp wire is thinner and cheaper than 100 amp wire.
Yes, if properly wired a 20 amp circuit is a great circuit for an 18 amp appliance. Properly wired means you've used 12 gauge wire or larger and the circuit is protected by a 20 amp breaker or fuse and all connections are secure.
Yes. It is abbreviated as AWG. For example, in residential wiring the size wire to use on a 15 Amp circuit would be 14 gauge or 14 AWG.
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).
14 AWG.
Use 8 gauge wire.
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
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.
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
Yes you can as long as it is feed off of a 20 amp circuit in at least #12 gauge wire.

You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
