Is single phase 240 v could support 5 unit air conditioner 1 HP each?

1 HP is 746 watts therefore 5 HP is 3730 watts. Allow 90% efficiency that means 4144 watts are required from the supply, allow a power factor of 0.8 which means that 5180 VA are required. Dividing by the voltage gives a load current of 21.6 amps, so a 30-amp supply should be all right.

Is Europe ac power single phase?
In Europe they have both single phase and three phase.
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 cannot be considered a single phase?
Any load that needs three legs from a three phase system can not be considered single phase. Single phase from a three phase system only needs a connection to two legs.
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.
Does single phase power damage air conditioners?
If the air conditioner is designed for three phase, then it will not run, and could be damaged, by single phase power. Otherwise, no.
Is air conditioner works on 1 phase and how it works on 3 phase also?
If an air condition is single phase, then it can only be connected to a single phase source. Since any two legs of a three phase source are considered single phase, there is no conflict, except to note that the individual phases of the three phase source match the voltage requirement of the air conditioner.
What phase are residential air conditioner units?
Most standard residential service is single phase. Therefore, I would say most all residential A/C units are single phase.
Is a 2 phase supply the same or equivalent as 2 single phase supplies?
Not necessarily. Two single-phase supplies could be supplying the same phase, which means you don't get the same range of voltage options you get with a true two-phase supply.
Can a single phase generator run a 3 phase air conditioner?
Depending on who does the work it could be less expensive than getting a different air conditioner. The compressor will also need a capacitor and some rewiring. The old unit could have a 3 phase blower motor also which could run the price up even more. Although the changes can be made, the warranty at best will probably be a one year warranty and a new unit could have a 5-10 year warranty.
Is the type of wiring in most homes single-phase or three-phase?
Single phase.
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
Is Europe ac power single phase?
In Europe they have both single phase and three phase.
How do you convert a 3-phase system to a single phase?
By having a transformer with 3 phase input and single phase out put
How different is the horsepower used by an air conditioner unit if it runs on either single phase or three phase ac?
There is no difference in horsepower. The manufacturer builds the air conditioner. Engineers calculate and tell the manufacturer how much power is going to be required to make it operate. Smaller units will probably use lower voltage with lower horsepower to operate efficiently. The bigger the unit will take higher horsepower to operate. There comes a point when single phase, low voltage use will not work due to the unavailability of high horsepower, low voltage motors. At this point three phase systems are used with higher voltages to operate the motors. Examples of a 10 HP motor at different voltages. Single phase - 115 volts 100 amps, 230 volts 50 amps. Three phase same HP - 200 volts 32.2, 230 volts 28, 460 volts 14 and 575 volts 11 amps. As you can see if the air conditioner needs a 10 HP motor at single phase 115 volts, a feeder supply of 100 amps would be needed. This compared to the same air conditioner using a three phase 575 volt system which draws 11 amps.
