Houses are not wired for three phase power as there is typically no need for that much power. 120/240 volts is the typical home voltage. Even some vary large houses (mansions) are still the same single phase voltage, just a very large amperage service (voltage times amperage is wattage, and use is rated in wattage). Utilities charge a base rate for homes that is usually in the range of $10-$30 per month, this is the charge when no electricity is used. For a three phase service, the charge is typically $125-$250 (depending on location and utility) per month before any power is used. Most all wires installed in a house are single phase. The black and white in 2 conductor with ground NM cable are suitable for only two of the three phases. 3 conductor with ground can be used, but that is not installed unless there is a purpose for the third wire that makes it unusable for the third phase. Three phase power must be designed into the construction of the house before it can be considered for a service, and then the cost is likely too high for the average owner.
Alternative Answer
The above answer applies to North America. But in other parts of the world, three-phase supplies to residences are quite common. For example, my house, here, in Cyprus, has a three-phase service. In these cases, the consumer panel has three separate line busbars, and the residence's loads are balanced between each line.

Is your house 120 or 240?
It is usually 240. Two lines enter your house, carrying 120 volts each, but they are out of phase by 180 degrees, so the two combined entering your house provide 240 volts, which is necessary for powering central air conditioning systems. You also have the option of powering everything else in your house with 120 volts because of the phase difference of 180 degrees without the need of a 2:1 turns ratio transformer in your house. You breaker box in you basement is wired to take advantage of this phase difference, supplying the 240 and 120 volt sources to the places that they are needed. This is a huge advantage of AC power.
What is the connection of normal wire star or delta?
normally delta connection wired in 3 phase induction motor. during starting wiring is in Star and after running normal speed changeover to delta .beacause starting time its phase voltage equals less root3 times of line voltage ,line current and phase current equals. in Delta phase voltage and line voltage equals, and phase current equals root3 times line current
How do you get 380 volt from 220 3 phase?
Only with a 3 phase transformer.
What would cause an electric motor to run backwards?
Motors running backwards: A DC motor wired backwards or magnetic field reversed. A 3 phase AC motor with 2 phases reversed A single phase motor will run either way unless it is 'persuaded' by means of a shaded pole or other method to rotate in a particular direction.
How can you prove that your house is wired in parallel?
Unscrew any lamp or disconnect any appliance. If the house is connected in series, everything else in the house will stop working!
Does a house that is wired 3 phase for about 50 years need to be rewired by code?
Yes.
Do they make 3 phase oven for home use?
Three phase ovens are made for home use. It is important however to know if the home is wired for three phase or for single phase.
Why 3 phase and single phase?
3 Phase system is for industrial use and 1 phase is for house hold application
What equipment is used to check phase rotation?
A phase rotation meter. Or a small three phase motor can be wired up and its rotation observed.
Does a 2 horsepower rotary converter plug into 120 single phase and convert it to plug in a 3 phase outlet?
All my experience with rotary phase converters have been in converting 240 volt single phase into 240 volt three phase. They all were hard wired into their respective systems, so my answer is no.
How does 120Volts single phase convert to 220Volts 3 phase when the 3 phase voltage should be 208Volts ie 120V x sq route of 3 equals 208V?
If you get 220 volts instead of 208 volts it means that the transformer supplying the circuit is wired in Delta with one of the legs center-tapped to ground.
When we get 220ac to our homes then how a device draws its required amount of volts or current from the power supply?
you are getting 120/240v to your house from your power company. this is considered single phase power even though two phases are used to get the 240v. any single phase to neutral (ground) will give you 120v. This is all wired in your load center in your house (fuse box) the wiring in your house is all wired in parallel, meaning that each circuit has the same voltage to it (either 120 or 240 depending on how it was wired) the resistance of the device plugged into the outlet will determine how much current is drawn by the device
What is a wireline?
The wired telephone connection from your house to the phone co wired circuits.
What are the release dates for In a Fix - 2004 The Wired House?
In a Fix - 2004 The Wired House was released on: USA: 17 February 2004
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 is a Chicago 3-way?
A Chicago 3-way typically refers to a hot dog topped with mustard, onions, and sport peppers. This combination is a popular way to enjoy a classic Chicago-style hot dog.
What was need of 3-phase?
it is mainly heavy loads.of course we can also use for our house hold purpose.if one phase is in shutdown mode,then we can easily get the supply by changing the phase
