No, a 230V supply is normally single phase, 50 Hz. It is the most common supply used in homes and offices in Europe and many other areas of the world.

In Europe, low voltage is distributed as three-phase, four-wire, supply system having a nominal line voltage of 400 V (line-to-line) and a nominal phase voltage of 230 V (line-to-neutral). So, yes, you could describe 230 V as being a 'three-phase' voltage.
Most residences are provided with a single-phase supply, which means that each home is connected between one of the three line conductors and the neutral conductor of a three-phase system. In some European countries, such as Cyprus, it is common for residences to have three-phase supplies, with the various circuits within the home being roughly-evenly distributed between each of the three lines and the neutral.
just eliminate one of the 3 phase wires or cap it off. but you will need a 2 pole breaker for the single phase.

Sorry but that answer misses the point of the question.
The phase voltages of a 3-phase service are quite different to the voltage of a single phase service so the question has not got that part right at all.
To get a single phase service from a 3-phase service, you use one phase and the neutral with the appropriate sizes of circuit breaker, cable and outlet to suit the load.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

It can be either, the voltage and 'phase' are different things.
Most domestic property, houses, flats etc, are single phase. Three phase supplies are more common in larger offices, factories etc. Some houses do have a three-phase supply (mine does), especially if a higher than normal consumption is expected.
In a house with a three phase supply most of the circuits in the house will be perfectly 'normal' wiring running between one of the three live phases and neutral. These circuits will be divided between the phases so as to make the average loads on the phases relatively even. High power circuits, possibly a large cooker, large A/C or a swimming pool pump will be connected to all three live phases.
In North America there are still some old three phase delta systems in use in industrial and commercial services. These applications will exist until the service distribution is no longer needed or an upgrade of the distribution is required to connect newer equipment to the system. The new services now are three phase four wire systems and include voltages such as 347/600, 240/480 and 120/208.
Homes are generally supplied with single-phase mains power electricity.

No. All residential wiring is single phase.
In both UK, Europe and North America 240 volts is a single phase voltage.
At least two cables: red/brown (live) and black/blue (neutral)
The process of obtaining 220 volts from 380 volts is quite simple. 380 volts is a three phase four wire system voltage. The 220 volts is obtained by taking the sq. root of 3 which equals 1.73 and dividing it into the phase voltage. 380/1.73 = 220 volts. This holds true with any three phase four wire voltage system. 208/1.73 = 120 volts, 415/1.73 = 230 volts, 480/1.73 = 277 volts and 600/1.73 = 347 volts. This lower voltage is present on any of the three phase legs of the three phase system to the neutral which is grounded on a wye connection.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
Yes, just use L1 and L2 ( just 2 of the 3 legs), or one of the legs to a neutral wire if equipped. Just make sure the voltage is the same as the 220 volts you wish to have with single phase service.
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.
No.
220 volts.
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.

Nothing happens. This is a normal way to obtain a single phase system from a three phase system.
If you have a voltage of 127 volts to neutral (ground) then your wye connected three phase leg voltages will have to be 127 x 1.73 = 220 volts. This voltage is within the 10% allowance for voltages as should operate the compressor. As the voltage is lower that specified, the amperage rating when a reading is taken will be higher than that of the equipments nameplate.
About 220 volts. They're just different voltage levels. 440 volt services can provide more power than 220 volt services typically.
