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.

What capacity generator do you need to produce 10 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.


If you have a circuit breaker box containing 650 amps of circuit breakers it is 3 phase 480 volts what size kva generator do you need?

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.


What size diesel generator would you need if there was a power outage?

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.


1200 watts is equal to how many amps?

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).


How many amps can a 9000 watt generator produce?

If your generator is rated at 1000 watts continuous......and you are using 120V.....available amps are 1000/120 =8.3 .


How many output amps is a 600kva generator at 240v?

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.


What size generator would you need to power a 200 amp tig welder?

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.


What size generator is needed to run a refrigerator?

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


How many amps does a 18000 watt generator supply at 240 volts?

75 Amps theoretically Need to know if the generator is 3 phase or single phase.


Can you install 60 amps generator and only get 50 amps AC power at 110 - 240 volts?

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.


How many watts does a whole house generator use?

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.
