AWG 12/2 with ground on a dedicated circuit with a 20 amp breaker. That will safely supply 1920 watts of continuous power.
Answer for USA, Canada and countries running a 60 Hz supply service.
Wire size is based on the amperage that the device draws. To find the amperage of any device use the following equation, Amps = Watts/Volts 2000/240 = 8.3 amps.
A #14 copper conductor with an insulation factor of 90 degrees C is rated at 15 amps.
Wire size is based on amperage of the load. I = W/E. Amps = Watts/Volts. As you can see with out a voltage stated an answer can not be given.
1500 watts at 120 volts will pull 12.5 amps. If you are wiring a 120 volt home circuit for this I would use AWG # 12 wire on a 20 amp breaker.
1440
Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80& of maximum. You need 14 AWG gauge wire.
A 12 gauge wire can support a load of approximately 2200 watts.
4800
AWG # 10.
1440
600 watts
Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80& of maximum. You need 14 AWG gauge wire.
To answer this question a voltage has to be stated.
5000 watts
A 12 gauge wire can support a load of approximately 2200 watts.
10 gauge wire will only run up to 30 amps
This is a voltage drop question and a voltage needs to be stated.
4800
AWG # 10.
1500 watts
1000 watts = 1 kilowatt 1500 watts = 1.5 kilowatts
