First you need to specify what voltage you require the generator to supply...Lets Assume its 240 Volts AC. Watts=Volts x Amps so 240x1200= 28.8 Kw.
Then you have to take the efficiency of the generator into account. Mechanical power in is usually quite a bit more than the electrical power you get out...The difference is mostly the mechanical and thermal losses added together. If we say the generator is 70% efficient then you will need a generator 30% more powerful to supply a constant 1200 Amps...Thats a generator of about 38-40 Kw.
The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
If your generator is rated at 1000 watts continuous......and you are using 120V.....available amps are 1000/120 =8.3 .
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.
To answer this question the voltage of the generator must be given.
Cross section area =60x10=600Sqmm For copper we can utilised 2 amps per sqmm hence we can load upto 1200 amps easily.
What is the generator amps
Small generators are sized in watts. Watts is the product of amps times volts. To properly answer this question a voltage for your 10 amps must be stated. That said small generator outputs are usually 120/240 volts in North America. So 10 amps at 120 volts equal 1200 watts. 10 amps at 240 volts equal 2400 watts. A 3000 watt generator will be amply for your 10 amp load.

The size of the generator is based on the size of the load you want to supply. Size up the load in watts or amps along with what phase (single or three) and voltage that the load requires. These are needed to give a complete answer.
To calculate amps, you need to know the voltage of the circuit. The formula to convert watts to amps is Amps = Watts / Volts. If the voltage is 120V, then 1200 watts would be equal to 10 amps (1200 watts / 120 volts = 10 amps).
If your generator is rated at 1000 watts continuous......and you are using 120V.....available amps are 1000/120 =8.3 .
To calculate the output amps of a 600kVA generator at 240V, you would use the formula Amps = kVA / Volts. In this case, it would be 600kVA / 240V = 2500 amps.
Generators are rated in watts or kilowatts. The formula for watts is W = Amps x Volts. To size a generator for the welder the voltage of the machine must be stated.
Depending on size of Fridge. But AVERAGE is 12 volts for fridge, circuit necessity 15 amps 15 amps X 120 Volts=1800 watts minimum...I'm LEARNING myself
75 Amps theoretically Need to know if the generator is 3 phase or single phase.
If you need 50 amps you can use a 60 amp generator or any other generator rated to supply more amps. The voltage, 110 v or 240 v, must be the right voltage for the load used.
The size of a generator is based on what the connected load will be. Add up all of the connected wattages that will be connected to the generator at one time and add ten percent, this will be the size of the generator you will need. Some equipment does not show the wattage on its nameplate. To find the wattage use the following formula Watts = Amps x Volts.
