probably about 50 hp
depending on how reliable the efficiency ratings of the various manufacturers are
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.
As example, at 380V the generator produces 685A per phase. Therefore you will require 2 x 120mm2 cables per phase. (1 x 120mm2 cable will support 365A per phase). In total you will require approximately 1/2km of cable to cover the 50m run between the generator and the ATS panel/Load. i.e. 5 phases in total - 2 x 50m cables per phase.
if your talking about a generator its not the hp of the engine its the size, rpm, and gearing of the generator motor
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.
This is a voltage drop to establish wire size question. For a correct answer to this question two values are needed. One value needed is the voltage and the other is whether it is three phase or a single phase installation.
The generator should be about ¾ hp.
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.
you need around 60000 watts on a dc current
You need a 5.5kw generator to run a 5.5kw motor.
You should get a 3 phase generator that has 8-12 KW. If you had to you could use a 3 phase 5.5-6 kw but it may wear out faster because you are using 100% power. The 3 phase gen will allow you to select 480 volt which can be converted to 380 for the mixer. The rpm of the motor in irrelevant because the generator is the power source in this situation, once the gen powers the motor it will produce 1140 to power the mixer.
To answer this question the full load amperage of the motor and what phase the motor is, should have been given. This answer uses the motor amperage give in the electrical code book and will be close for your purpose. A 6 HP is not a common size motor. 7.5 HP motor is 25.3 amps. Using a power factor of 90%. W = I x E x 1.73 x pf, W = 25.3 x 220 x 1.73 x .9 = 8666 watts. A 10kW three phase generator will probably start the motor if it is not under load when it starts. A 15 kw generator would be better. A single phase 7.5 HP motor draws 40 amps. W = I x E x pf = 40 x 220 x .9 = 7920. Again A 10kW single phase generator will probably start the motor if it is not under load when it starts. A 15 kw generator would be better.
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.
Yes, a 2800 watt generator should be able to run a 550 watt electric cement mixer motor. The generator's wattage is more than enough to power the motor with some extra capacity for other devices. Be sure to check the starting wattage of the motor as well to ensure the generator can handle the initial surge of power needed.
The size of diesel generator varies greatly. The size that is needed would depend on the size of the house.
To answer this question a voltage must be given to find the current output. Also whether the generator is three phase or single phase.
As example, at 380V the generator produces 685A per phase. Therefore you will require 2 x 120mm2 cables per phase. (1 x 120mm2 cable will support 365A per phase). In total you will require approximately 1/2km of cable to cover the 50m run between the generator and the ATS panel/Load. i.e. 5 phases in total - 2 x 50m cables per phase.
The electrical code book states that a single phase 3 HP motor at 230 volts draws 17 amps. This equates to 3910 watts. Allowing for starting inrush current a 5000 watt generator will run the motor but the generator will labor a bit until the motor gets up to speed. Generators with a higher wattage rating would have less trouble with the starting of the 3 horse power motor. <<>> One hp is 746 watts. 3*746=2238. It takes 3 to 6 times as much energy to start as it does to run.
