One HP = 753 watts, so the simplest formula to get your answer would be:
kW = HP/0.753
But that assumes 100% efficiency & a 1.0 power factor. Motors on compressors typically have a power factor of .7, but that can vary from .4 to .8 The power factor is the algebraic form of the nonlinear relationship between watts and volt-amps in an AC system. Always assume that a generator's rating is actually volt-amps and not watts, and you won't have a problem with your loads.
You should also add in a safety factor. So, the formula would be:
kW = SF * ( 1 / efficiency ) * ( 1 / PF ) * ( HP / .753 )
Putting in some typical real world values:
kW = 1.25 * ( 1 / 0.8 ) * ( 1 / 0.7 ) * ( HP / 0.753 )
I don't have a calculator handy so I'll let somebody else punch the numbers :-)
What else can I help you with?
Could works a 500 watts of power and 3 phases motor with a wind generator?
Yes, but it would have to be a pretty big and expensive wind generator. You would need an inverter to produce at least 500 watts of 3 phase power. Unless you also had some big batteries, you could only run your motor when the wind is blowing!
If my house has a 200 amp line what size generator would it take to run the house and have the same power?
Your house runs nowhere near 200 amps, so you need to make a list of appliances and fixtures that you use, or that you will need while the generator is running, and add their power consumption together. Add some extra capacity for growth and so the generator is not always at full power. Then talk to dealers about generators with the amount of power you need. To run the house on a generator with the same capacity as the service that you have in your house you would need a 50 Kilowatt generator.
How would you make a patch cord to go from a 220V 30-amp 4-wire generator to run a 220V 20-amp 3-wire portable compressor?
To make a patch cord for this setup, you will need a 4-prong 220V plug that matches the generator's outlet, a length of appropriate wire rated for 30 amps, properly sized for the distance between the generator and compressor, and a 3-prong 220V plug that matches the compressor's inlet. Connect the wires according to color-coded standards (red and black to the hot terminals, white to the neutral terminal, green to the ground terminal). Make sure the wire gauge matches the amperage rating to avoid overheating.
What size generator would power a two bedroom house?
I power my home from a 7000 watt generator. It connects to a 12 circuit transfer panel. Backup power is supplied to the well pump, fridge, freezer, furnace, microwave and toaster ovens, television, computer, and several lights.
Would the electricity needed to heat a house come from a generator or a dry cell?
The electricity needed to heat a house typically comes from the grid or a local power plant, not from a generator or a dry cell. Generators are usually used as backup power sources for temporary or emergency situations, while dry cells, like batteries, are not designed to provide the continuous high power output required for heating a house.
What size of generator do you need to power 30 kW Air compressor?
To power a 30 kW air compressor, you would typically need a generator with a capacity of at least 37.5 kW to account for starting surges and ensure reliable operation. It's advisable to choose a generator with a higher output, such as 40-50 kW, to provide a safety margin and handle any additional loads. Make sure the generator is compatible with the air compressor's voltage requirements as well.
How do I change to a gas power generator?
If you were wanting to change an electric power generator to a gas power generator, I would probably not do it on my own. Instead I suggest you call a professional to change it for you.
Where can I find information that compares a gas generator versus an electric generator?
A gas generator generates electricity and can be used as a backup in a power outage. I am not certain what you mean by an electric generator. If there was a power outage, how would an electric generator work?
Is an electric power generator safer than a natural gas powered generator?
You can purchase an electric power generator, but it won't do you much good if the electric goes out. A kerosene or deisel generator would be a better choice.
Where do you buy power generators?
Power generators are available at Home Depot, Rona and Canadian Tire. Amazon have a generator buying guide that would explain what is a power generator.
What size generator do you need to move a 30 hp electric motor?
A 5 kW generator would turn it over but if the full 30 hp of mechanical power is needed, that would require about 30 kW of electric power from the generator.

What is governor function in the generator?
The governor controls the speed of the power source rotating the generator. This has to be continually adjusted to match the load on the generator. As more load is switched on, the generator becomes harder to turn, this would cause the generator to slow down, unless the power unit is adjusted to increase power and correct the speed.
When would you use a standby generator?
You would use a standby generator as a back up electricity source when there are outages of electric power. Business such as factories and also offices would have a standby generator in place.
Is a gas generator better than electric?
The purpose of a generator is to generate electricity. An electric generator would be redundant. It would need electricity to make electricity and when there is a power outage there is not electricity.
Why is there no power going to the compressor?
Assuming you are asking about the ac compressor, there would be two possibilities, blown fuse or low on freon.
Where can I find a backup power generator?
There are many places you can find a generator if you want to keep it quite low on the price I would check lowes, home depot, craigslist or amazon. A backup power generator is an extra source of power so if someone runs their power off of a generator and it goes out they will have another one to use.
