I have moved what you have written to the discussion page, where we can carry on with more details if you need them.

First of all the US does not have 2 phase power systems. What North America uses is a split phase secondary that is used to power home.
In a single phase service, the output secondary coil of the transformer on the pole has three bushings coming out of the transformer. On the two outside bushings is the working voltage (house connections 240 volts). The middle bushing is a centre tap of the secondary coil. This gives a voltage of (bushing left to centre 120 volts) and (bushing centre to bushing right 120 volts) The centre tap of this transformer is grounded. The single phase service neutral is established at this point. These three secondary points are connected by triplex to the homes weather head where another connection is made to the homes service distribution. This is classed as a 120/240 volt service.
Your appliance from England requires 240 volts to operate. To obtain the voltage from the North American system it will have to be connected across L1 and L2. In the distribution panel you will need 2 adjacent breakers to obtain this voltage. The size of the breaker to supply the appliance will be based on what the load amperage is of the appliance. The proper size conductors will have to be installed to a 240 volt receptacle, again the pin configuration will depend on the load amperage of the appliance.

Can a homeowner buy appliances for a home that has a 120-208 three phase service supply?
If appliances cannot be found, it is fairly easy to wire it for single phase from a 3 phase supply. Most electricians can accomplish this task and it is a little more involved than a homeowner usually can do.
How many wires come in from the weather head?
If single phase - 2 wire service > two wires If single phase - 3 wire service > three wires If three phase - 3 wire service > three wires If three phase - 4 wire service > four wires US residential service is usually single phase 3 wire service: Two hots and neutral.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
What is the difference between single phase circuit and tree phase circuit?
single phase have 2 wire treephase have 3, and 4 wires
How many single phase can you run on a 100amp 3 phase?
You can divide a three phase service into (3) single phase circuits providing you have a 4th neutral wire.
What is meant by three phase?
Three phase power is a method of electric power transmission using three wires. Three phase power systems may have a neutral wire that allows the system to use a higher voltage while still allowing lower voltage single phase appliances. In high voltage distributions, it is not common to have a neutral wire, as the loads can simply be connected between phases.
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.
Explain briefly the difference in application between single and three phase distribution installation?
A simple single-phase installation for an average European house has a supply provided on two wires, the live and the neutral, with a nominal voltage of 230 v. Single phase supplies are usually rated at 60 or 100 amps. In countries which use 120 v appliances the property is usually supplied with a split single-phase system on three wires, with one neutral and two lives. The voltage across the live wires is 240 v for high-power appliances, while neutral to either live wire is 120 v for lighting and low-power devices. The common European three-phase system has one neutral and three live wires with 230 v between neutral and each live wire, but 400 v between live wires. Groups of houses and other small properties have a three-phase supply, with each property connected through a single-phase spur using one live wire and neutral. Large houses and small businesses might each have their own three-phase four-wire supply.
What wire size for 100 amp single phase 3 wire commercial service?
2 copper
How many earth wires are required for single phase motor?
There is only one ground wire needed on any motor, single or three phase.
Do you get a shock when you touch the phase wire of single phase?
Only if you are grounded and provide a return path for the current to travel.
How do you ground one of the phases from three phase three wire in order to make single phase?
you can't do this. to get single phase from 3 phase you must disconnect 2 of the phases and use one of them as a neutral...b.
