It depends on the voltage of the compressor. Two horse power (electric) is 1492 watts, but watts are volts times amps, so you need to know the voltage. Since the motor is an inductive load, you will also need to know the power factor, so as to compensate for true vs apparent power.

FLA: Full Load Ampere. Its the current drawn by the motor when the motor is running at full load FLA = kW / (1.732*V*pf*efficiency*100)
The SI convention is that all SI units, when written in full, are written entirely in lower-case letters. For those units named in honour of individuals, only their symbols are capitalised. For example, the SI unit for power is written as watt but, because it is named in honour of James Watt, its symbol is a capital W.So it is incorrect to capitalise ampere (not amp!).
Assuming your power supply is 230 volts, single phase: Full load amp draw = 21, circuit breaker = 50, minimum wire size = 10.

Mabe your compressor is not kicking on for some reason. Check to see if the front of your compressor starts spinning when you turn it on. If it don't check to see if there is power to the wires that go to your compressor. If there is power you have a bad compressor. If there is not check the fuses or relays.
The voltage for the air compressor is needs to come from a double (two) pole breaker. The size of the breaker needs to be 250% of the full load amps of the compressor. The wire size to the compressor has to be 125% of the full load amps of the compressor.
Full load current can be calculated by the formula given below: P=SQUARE ROOT OF 3*V*I*POWER FACTOR P=1.732*V*I*PF suppose 3 kw motor three phase voltage assuming .85 power factor and 415 volt full load current will be 3*1000=1.732*415*I*.85 I=4.9 ampere(full load ampere)
