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.
You will need a 50 kW generator for a single phase 120/240 volt service.
To calculate the power needed for the battery charger, you multiply the voltage (110V) by the amperage (40A) which equals 4400 watts. Therefore, a 110V generator with a capacity of at least 4400 watts or higher would be needed to power a 40 amp 12 volt battery charger.
Using 110 volt service, 5,000/110= 45 amps
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.
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).
