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.
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.
AWG # 10.
4800

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.
AWG # 10.
4800
1500 watts
1000 watts = 1 kilowatt 1500 watts = 1.5 kilowatts
Wire gauge is determined by the capacity in amps. At 120 volts it requires 8.33 amps to provide 1000 watts. The typical residential application would require 18 AWG wire 1.024 mm in diameter.
