Can an American 240V dual phase dryer be converted to work in Korea with 240V single phase power?
you could possibly design a fix for it but it would be a lot of trouble. the American dryer has internal components that run off 110v and that 110v is available from the three wire 220v circuit in the typical usa residence. this is because of the third wire, the neutral. the Korean 220 would be 2 wire. you would have to go inside the dryer, add a 220/110 transformer and rewire the dryer so that the 110v loads come off that transformer. it would then no longer be ul listed and would have to be evaluated by the authority having jurisdiction in Korea and back here in the usa.

No...but you can buy an "autotransformer" that will boost the 220 to 277. Transformers of this kind can be the auto type or isolation type and are available at a …much higher cost that it would be to just buy 220 volt ballasts and sell the 277 ones at your next yard sale. The fluorescent lamps probably won't start with such a severe undervoltage (80% rated). If they do start, they won't work well and the lamps will have reduced life.
Answer for USA, Canada and countries running a 60 Hz power supply service.You use a single phase 480 to 240 volt step down transformer. Connect the primary across the 480 volt…s and your load across the 240 volt side. Make sure that the transformer has a high enough capacity to carry the load with out getting into an overload condition. The proper size fusing of this transformer can be done on the primary side of the transformer which will protect the secondary side load. As you asked this question here the best advice anyone should give you is to call a licensed electrician to install a new 240 volt circuit with the right breakers, wiring and wall outlet for the appliance you want to use. 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. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you operating 240v 60hz single phase electric kiln on 240v 50hz single phase power supply system?
If the kiln is strictly a resistance heating element, with no motor, then yes, it should work fine. Warning: the opposite, that is running a 240V 50hz (European) applianc…e from US 240V 60hz mains is very dangerous and should not be attempted. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.
If you have both 220V 3 phase power and 110V single phase power can it be converted to 220-240V single phase power?
If you have a 220v three phase delta system, the phase-to-phase voltage is 220v single phase; hence, no conversion is necessary. Don't worry about 220-240v rating, the v…oltage rating is nominal. Your 110v single phase has actually already be taken from a center-tapped transformer on your three phase system.
How do you get a split phase 120v 240v power supply from a single phase 240v supply for an American RV with a 50 amp service?
This is a common misconception. A standard 240 utility feed, common in the US, and a 120/240 feed are one in the same, the exact same thing. It is called (historically) an Edi…son connection. If you have a 240 volt single-phase supply, with two hot conductors, a neutral, and a ground wire, then you already have 120/240 service. If you do not understand the terms above, then hire a qualified electrician to make the connection for you.

a lot of the MH fixtures come with multi tap ballasts. if you open fixture and find multiple wires and one that have 240 on it tie it into one hot and the other hot into one o…f the common wires.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load ac…ross them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
240v x 13.5A = 3.24kVA, single phase transformer.
You can buy a 1 to 1 (or 1:1) multi-tap isolation transformer sized to handle 260v and whatever volt-amps you intend to run. It will come pre-wired to give you the same output… voltage as you supply, 260v in your case. But the multi-taps allow you to adjust the output voltage up or down depending on your needs. Choose the taps that give you a voltage as close to 240v as possible. This is not a do-it-yourself project. The primary and/or secondary must be protected by over-current devices and it must be properly grounded.

Answer for USA, Canada and countries running a 60 Hz supply service. To convert 480 volts single phase to 240 volts single phase you will need to use a step down transformer.… Any two legs of a three phase system is classed as single phase. The primary side connection will be any two legs of a 480 volt three phase system. H1 to H2 will be 480 volts. On the secondary side of the transformer the connections will be X1 to X2 which will give you the required voltage of 240 volts single phase. Depending on what the secondary side load current draws will govern the size of the transformer. The formula to calculate the transformer size is KVA = Amps x Volts/1000. Connect a 2:1 ratio step-down transformer across any two line conductors of the three-phase supply, and the secondary will provide a 240-V single-phase supply. Unless you are qualified to do so, don't do this yourself, because the circuit will require the installation of overcurrent protection devices such as fuses or circuit breakers, in accordance with the relevant regulations, to make the installation safe.
You cannot. There is only single phase and three phase. Both come from the power company in wire distribution configurations. I believe in the Eastern united states there are …still some two phase systems. If memory serves these systems have voltages that are 90 degrees apart. Sometimes three wires are used to provide two phase service - the two phases and an oversized neutral wire that is used as the return for both phases. Since there is a phase shift involved to get two phases from one, you must have a phase shifting device to accomplish this. It is generally easier to get two/three phase service from your local utility company as opposed to try to generate it yourself.
In some situations 240 volts is classified as single phase. So the answer to your question, the way it is stated is, yes.
used only the two line of a 3-phase system. ex. used line 1 and line 2 only, or line 2 and line 3 or line 3 and line 1 to have a 240v single phase. The above answer has the q…uestion backwards. No, you can not obtain three phase supply from a single phase supply with out spending a bit of money. If you are asking this to make a motor connection then that can be done. 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.
How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can co…nnect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
Any two legs of the 480V will give you 240 V Single phase. I apologize for the wrong information here. A friendly member reminded me of the correct answer. I stand correct…ed. Any two legs would be at 480 single phase. One leg to neutral will give you 277volts not 240 (408/1.73). You would need to install a step down transformer on the 277v line to achieve 240v.
