The formula you are looking for is W = I x E. I = W/E. A = W/V.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
Typically 75 amps on natural gas, 85 amps using propane. Peak amps(for less than a second) to start a big appliance, like an A/C condenser, are 130.
amps*volts=watts 40 amps *12 volts= 480watts watts/volts=amps 480watts/110volts=4.36363636amps So you need a 110 volt generator that can produce about 5 amps as a bare minimum. To take into account system heat loses that occur when converting power consider doubling it to be safe. (this is over kill but the advantage is that your generator is not working at full capacity at all times)
At 240 volts, and 7 amp current, you will have a load of 1680 watts (volts x amps = watts). A 2000 watt generator will sufice, however a 3500 watt generator, if within your budget, will power a few other necessities if required.
62.5 amps
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
If your generator is rated at 1000 watts continuous......and you are using 120V.....available amps are 1000/120 =8.3 .

It depends upon the Generator system voltage. For 3 Phase, 600 Volt system, it will be 73 Amps For 3 Phase, 480 Volt system, it will be 90 Amps For 3 Phase, 208 Volt system, it will be 208 Amps

Current (amps)=Watts/Volts =2000/120 =16.75 =16.75 amps
A 3000W 110V generator can provide up to 27A.
Generators are rated in volt-amps (va) and may also have a wattage rating. In most practical applications volt-amps and watts are the same. At 240v single phase, 400 amps is 96000 volt-amps, or 96kva. I would be looking for a 100 kva generator. This is a large generator if you are considering it for your home. In most situations you identify critical circuits and place only these on the generator through a transfer switch. This allows for a much smaller generator.
