A standard household AC mains power supply, either 220-240 Volt 60 Hz or 50 Hz, is already a single-phase supply so it will not need to be converted. For more information please see the answers to the Related Questions shown below.

∙ 15y agoyes it can be done by using a 1 phase trnsformer with proper turns ratio in this case it would ideally be 208:230 but in real situations we will have to for 208:x (where x>230) this is due to leakage flux and voltage drop due to resistance of the coils

∙ 12y agoI own a deli and have a meat cutter that someone wants to sell me. My store is supplied with conventional 220-240 single phase electrical system. The meat cutter is 3-phase 220-240volt 60-50hz. Is there a way to convert my conventional single phase 224-240 volt 60-50hz to accommodate the 3 phase 220-240 volt 60-50hz that the meat cutter needs to use?

The physical internal windings between single phase and three phase motors makes this an impossibility That being said money can make anything happen. Depending on the amount of money you want to spend to make this happen there is a device on the market called a VFD ( Variable Frequency Drive). On the three phase input terminals you apply your single phase voltage. On the output terminals you connect your three phase motor. When run in this configuration there is an internal switch that has to be changed to let the VFD know that it should be looking for only two lines on the input to be hot. Other wise the VFD thinks that there is a line loss on the three phase input terminals and the unit will not start.

∙ 13y agoTwo phase systems are no more. They were replaced by the three phase system which is what we use today. If you are talking about drawing 220 volts from a three phase system then all that has to be done is use any two of the three phase legs. When this is type of connection is used it is known as taking single phase from a three phase system. In North America a common three phase wye system is 120/208 where between the phase wires the voltage is 208 volts and between any phase leg and the star point (neutral which is grounded) the voltage is 120 volts.

∙ 14y agoYes, I could explain how but it requires rewiring inside the main electrical panel. You should have a qualified electrician do it.

Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
How do you convert a three phase power supply into single phase power supply?
You can take three separate single-phase circuits from a 3-ph generator. Just use one of the live wires plus the neutral to make a single-phase supply. <<>> A three phase generator does not have to be converted to single phase. In electrical terminology any two legs from a three phase system are classed as single phase. No matter what voltage the generator is producing, L1 - L2, L2 - L3, L3 - L1 are classed as single phase legs along with L1 - N, L2 - N, L3 - N. If the generator output voltage is not the voltage that you are looking for use any two legs of the generators output voltage and use a transformer to obtain the voltage that you need.
How can I connect a single-phase - 2 hot wires plus ground- 220V load to a 3-pole 220V breaker?
Common usage of a three pole breaker is for use on a three phase distribution panel. Single phase distribution panels only use two pole breakers for a 240 volt load.Remember that the breaker must protect the conductors that connect to the load. If you want to try and use a three pole breaker in a single phase panel just because you have the breaker, this is not a good idea even if it will fit.Purchase the proper single phase two pole breaker to match the wire size and the amperage of the connected 240 volt load. Keep in mind that connected 240 volt motor loads have to be sized to 250% of the motor's full load amperage.By doing what you want to do and a fault occurs from this type of installation your insurance company might not cover the damage that it would cause.If the distribution panel is three phase then just connect the two load wires to any two of the three poles on the breaker.
How do you convert 3 phase to 220 v single phase?
Single phase 220 V AC(measured Across the line and Neutral) Three wire system having one Live(L),one Neutral(N),one ground's. Two wire system having one Live(L),one Neutral(N). Two phase 220 V AC (measured Across the two phases i.e across Phase RY or across Phase YB or across Phase BR) . Three wire system having tow live (L), one Ground (G). Two wire system having two Live(L). Ramesh P
Why is it called single phasing?
On a three phase system you have incorporated into it a potential of three single phase systems. A-B, B-C, C-A. Any two legs of a three phase system can be used as a single phase load. On a three phase system, be it a motor or a service, if one of the legs drops out for what ever reason, the remaining two legs are known as single phase. This is how the terminology became single phasing. As a side note a motor will run in a single phase condition, it just will not start. In motor control, a single phase condition is prevented by the use of overload heaters on all three voltage legs.
How do you run a 220V from the box?
Three phase or two phase? Three phase requires three large wires for the current needed

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
How you can convert 1-phase voltage to 3-phase voltage and vice-vars a?
A single-phase supply is obtained between any two line conductors or between a line and neutral conductor of a three-phase supply. To obtain a three-phase supply from a single-phase source is far more difficult, and requires additional equipment.
Does a two phase heater need a two phase thermostat?
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.

How do you connect two single phase watt-hour meters to measure three phase lines?
Two single phase meters are not needed. A three phase meter is manufactured and is used when installing a three phase electrical distribution.
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.
Is a 220 volt single phase in the US two single phases of the same sine wave?
A single-phase supply needs two wires to allow the current to circulate.
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.
