yes we can use as a single phase circuit because at practise directly the 3-phase circuit is made by combining the three single phase circuits

Can you use a 2 pole breaker for a 120 volt single phase circuit?
A single phase circuit uses a 2 pole breaker if the circuit is 120/240 split phase and the load is connected 240. Both legs are hot, so both need to be protected. This is the normal US/Canada configuration.
Can you use 240 volt 3 phase to run a machine that is 240 volt single phase?
Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
What are advantages of three phase ac and a single phase ac?
In a typical 3 phase system you have multiple voltages and configurations that can be used in either single phase or 3 phase, depending on how the circuit is designed. A single phase system is just single phase. You can have multiple voltages but it is always single phase.For example, in a typical 277/480v 3 phase system you can power 277v single phase lighting or equipment, 480v single phase lighting or equipment (which uses 2 legs of the 3 phase system but operates like any other single phase circuit), or 480v 3 phase motors.When comparing motors, a 3 phase motor will be substantially smaller than a single phase motor of the same horsepower. You can also reverse a 3 phase motor by switching any 2 leads. A single phase AC motor runs in one direction regardless of how the leads are connected.AnswerFor a given load, a three-phase transmission system requires less volume of copper in terms of conductor size, compared to single phase, so it is more economical to use three-phase.
What will happen if you use phase to phase voltage for a single phase device?
Phase to phase, two wire is classed as single phase. If the voltage from the phase to phase match the device's operating voltage, then connecting the device will allow it to operate.
Use of single phase and three phase variac in electrical engineering?
single phase variac can give 0-270 voltage in ac forms. So it is used to know the voltage in any circuit.
How many amount of current flow in spark use 230 volt single phase supply?
It is limited by the size of the fuse in the circuit.

How do you connected 3 phase motor to single phase power?
Use VFD to make 3 phase from single phase source.
Can you get 220 VAC single phase by using the ground and one of the hot wires in a 440VAC three phase circuit?
Use a transformer. A 208-240v single phase line has 2 power leads. Consult your local electrician for help! 440v systems are not for toying with when questions like this are asked.
Do televisions use single-phase or 3-phase power?
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
How do you converter single phase to three phase?
you can use a rotophase
How can you use a 3 phase capacitor as a single phase capacitor?
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
How do you convert a three phase power supply into single phase power supply?
You can take three separate single-phase circuits from a 3-ph generator. Just use one of the live wires plus the neutral to make a single-phase supply. <<>> A three phase generator does not have to be converted to single phase. In electrical terminology any two legs from a three phase system are classed as single phase. No matter what voltage the generator is producing, L1 - L2, L2 - L3, L3 - L1 are classed as single phase legs along with L1 - N, L2 - N, L3 - N. If the generator output voltage is not the voltage that you are looking for use any two legs of the generators output voltage and use a transformer to obtain the voltage that you need.
Why to use 3 phase instead of single phase in industry?
Two phase and three phase electrical circuit have more energy in them, in a given time (cycle) that single phase. I believe two phase had twice the energy as a single phase circuit, and 3 phase has 3 time the energy.You can get the same energy (H.P., work) done with a single phase circuit (motor), but you'd need to draw more current (twice the current compared to a 2 phase circuit.) If you examin a motor that can be wired either 110, or 220 VAC, you'll note that the current for the 110 VAC is twice the current for the 220 VAC wiring.Two and 3 phase circuits allow motors or other high power industrial devices to pack more horsepower into the device, without drawing excessive amount of current. Larger current would demand larger wiring, breakers, etc. driving up costs.AnswerFor a given load, a three-phase supply requires around 75% of the volume of copper compared to a single phase supply and, therefore, is more economical. Also, three-phase motors are more compact, and are self-starting. Two-phase supplies are archaic and unlikely to be seen these days.
