No. Most home services in the US and Canada are 230V single (split) phase.
Answer (for European Systems)
230 V is the standard nominal single-phase voltage for European low-voltage distribution systems.
In urban (and built-up rural) areas, low-voltage distribution is practically always a three-phase, four-wire, system by means of underground cable or overhead line. This provides a 400 V line voltage (line-to-line) and a 230 V phase voltage (line-to-neutral).
In rural areas, individual buildings such as farm houses, may be supplied with single phase directly from a distribution transformer (e.g. in the UK, using a pole-mounted 11-kV/230-V single-phase transformer).
In most cases, residential buildings are provided with single-phase supplies but, in some countries, residential buildings are provided with three-phase supplies.

HOW and Why there is 440v supply in three phase and 230v supply in single phase?
In a three-phase system, the voltage is measured between any two of the three phase conductors. The voltage between two phases in a 3-phase system is higher at 440v compared to a single-phase system where the voltage is measured between one phase and a neutral wire, resulting in 230v. The higher voltage in three-phase systems allows for more power to be transmitted efficiently over long distances.
What is meaning for TPN isolator and SPN isolator?
TPN (Triple Pole and Neutral) isolator is an electrical switch used to disconnect three-phase electrical circuits, ensuring that all three phases and the neutral are isolated for safety during maintenance or servicing. SPN (Single Pole and Neutral) isolator, on the other hand, is used for single-phase circuits, allowing isolation of the live wire and the neutral wire. Both types of isolators are crucial for ensuring safety by preventing accidental energization of circuits during work.
How is it wired or terminated to a phase if all circuits are on the same phase or hot legit would be limited to one neutral?
The question makes no sense.
What are the advantages of three phase circuits over single phase circuits?
3-phase is used to transmit power over distance because less wire is needed for a given amount of power. 3-phase induction motors produce a steady torque and don't need a starting coil to make them start rotating the right way.
What does short circit mean?
short circuite means phase to phase,three phase short, phase to earth, three phase to earth, this is all short circuite
Is a 3 phase cable one circuit?
If it is powering a single 3 phase device and is protected by a single throw 3 pole breaker or disconnect, yes. If all three hots share one neutral, and supply different devices or circuits, breakers should be able to trip independently but would still have to disconnect all three phases together.
Are all 480 Volt light fixtures 3 phase or are some single phase?
I do not believe any lighting fixtures of any voltage have ever been made to work off of three-phase circuits. Light Fixtures are always single-phase 2-wire circuits In the USA the standard voltages for branch circuits are: 120, 208, 240, 277 or 480 The light fixture must be rated to match whichever field voltage is being used. Some light fixtures are made multi-rated so they can be used on more than one circuit voltage
How is a three phase agricultural motor used when there is no power supply?
With no three phase power supply you can't use a three phase motor of any kind at all!
What is a star star connection used for?
A connection is one or the other, star or delta in a three-phase system. Delta has the three loads connected between the live lines, while star has the loads connected from the live wires to a neutral point. In the power supply industry delta connections are normally used at high voltage because the circuits are three-phase 3-wire, with equal currents in all three phases. At low voltage (below 1000 v) the circuits are usually three-phase 4-wire using a star-connected transformer secondary, which allows a lot of separate single-phase loads to be supplied, each one between one of the live lines and the 4th neutral wire. That is how power is supplied to a group of houses.
Is it ok to run three 240 on one 50 amp breaker?
If you are asking, can three separate 240 volt circuits be run off of one 50 amp breaker then the answer is no. Not without knowing what the loading of the three circuits are and whether all three circuits could be on at the same time.
3 phase 220 volts to 1 phase 220 volts?
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.For more information see the answers to the Related Questions shown below.Another ViewIn 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.
What is a balanced three phase system?
A balanced three phase system is where the currents into the loads placed on all three phases of the service are reasonably close to each other in amperage.Another opinionA 'balanced' three-phase system describes a three-phase load in which each phase current is identical in both magnitude and phase. If the phase currents are only 'reasonably close', then the load is not balanced.
