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.
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.

A 16-gauge wire typically has an amp rating of around 10-15 amps, depending on the type of insulation and wire composition. It is important to consult the manufacturer's specifications or a professional electrician to ensure safe and proper usage.
If the full load amps rating of the motor on the name plate is exactly 15 amps you need to use # 12 wire. If it is a longer run you may have to go up one more wire size. The breaker size you need is 30 amps.
A 3/0 copper conductor with an insulation rating of 90 degrees C is rated at 225 amps.
The amp rating for 10-3 wire is typically around 30 amps.
The amp rating for 6/3 wire is typically around 55 amps.
The amp rating for a 4/3 wire is typically around 100 amps.
The amp rating for a 6-3 wire is typically around 55 to 60 amps.
The amp rating for a 3 gauge wire is typically around 85-100 amps.
The amp rating for 10 wire is typically around 30 amps.
The amp rating of an 18AWG wire is typically around 16 amps.
The amp rating of 10AWG wire is typically around 30-40 amps.
The amp rating for 10-2 wire is typically around 30 amps.
The amp rating for 10/2 wire is typically around 30 amps.
The amp rating for 18 gauge wire is typically around 16 amps.
The amp rating for an 18 gauge wire is typically around 16 amps.
