This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.
Houses generally run on single phase power. It would not make sense to convert single phase to three phase to run a house. Please restate the question.
Va=volts x amps. The K stands for one thousand. So 1 Kva is one thousand watts. So 415v times 120a= 49,800 what's. You divide that by a thousand and you get 49.8. So it would be 49.8 Kva.
Most 3-phase welders cannot be made to function on single-phase power. If your welder is an inverter type, such as a Miller Dynasty or Lincoln Invertec, then it may have a single-phase mode with reduced current output. You would have to download the manual for your particular welder. If it is an older transformer (big and very heavy), then you're probably out of options here.
If the generator is a 12 lead reconnectable, you can use something called a zig-zag connection.Check the link below. It is an installation manual for a Marathon generator. Zig-zag connections are shown on page 8. For a home, you would use the low zig-zag connection for 120/240V (in the US). One caveat: you can only load a zig-zag single-phase connected generator to a maximum of 66% of its rated load. So, a 15kW 3-phase generator would only provide 10kW single-phase power. If this doesn't quite make sense, hire a pro!IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
noAnswerWhereas most countries have single-phase residential supplies, some countries, such as Cyprus, often have three-phase supplies. The main distribution panel ('consumer unit') must be designed and assembled to accommodate either a single-phase supply or a three-phase supply; you cannot use a single-phase distribution panel with a three-phase supply.
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.

To calculate the amperage, use the formula: Amps = Watts / Volts. For a 3000-watt load on a 220-volt AC single-phase circuit, the amperage would be approximately 13.6 amps.
The winding design of the motor will not economically allow this to work. You would have to drive a 3 phase generator to supply it.

No, a single-phase supply cannot be directly used in a three-phase system. The voltages and phases are different, so additional equipment such as a phase converter or transformer would be needed to convert the single-phase supply to match the requirements of the three-phase system.
500,000 watts/240 volts = 2,083.34 Amps (single phase)
Phase converters are devices that convert single-phase electrical power into three-phase electrical power capabilities.They may be required in Europe, the UK and Australia, to name just some areas.
In a three phase that means there are three lines live. Lets name the first line L1, second one L2 and the last L3. If you would connet it to a three phase motor then you require L1, L2 and L3 to be connected either in star or delta connection. Rating of your motor should be 200V, 3 phase , x HP ( star or delta connected). If you have a single motor of 200V then you only need to connect two lines of the three., namely either L1 to L2 , L1 to L3 or L2 to L3.
No. That would be a single phase motor.
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
To convert 2 kW to kVA in single phase, you need to know the power factor. If we assume a power factor of 0.8 (common for many single-phase loads), the conversion formula is kVA = kW / power factor. Therefore, for 2 kW at a power factor of 0.8, the result would be 2 kVA / 0.8 = 2.5 kVA.
