A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give you 120 volts.

230V line to line a single phase?
Yes. 230V line to line is considered single phase power. The 115v half part of that is called split phase. It should not be called two phase, as it is one phase that has been center tapped and grounded at the neutral point - it is still one phase power.Answer230 V is the standard nominal voltage for residences in Europe. 230 V is the line-to-neutral voltage (phase voltage). Low-voltage distribution is by three-phase, four-wire, system with a nominal line voltage of 400 V and a nominal phase voltage of 230 V.
How can I convert standard American 240 volts 3 phase to 1 phase 2 wires 1 hot and 1 neutral?
It doesn't need to be converted. The 240 Volt single-phase electricity is there already to operate any single phase devices. New breakers, the right size of wiring and a new wall outlet are what have to be installed to add a new single phase 240 Volt circuit to an existing breaker panel which already has a three-phase supply. For safety reasons only a trained and licensed electrician should work with this equipment. Careful! The statement above can be misleading. The Asker is obviously not from the US, he thinks US 240V is three phase, when its really single-phase. But note that he wants to convert to single-phase with one hot and one neutral. This is consistent with European standards with 230V single-phase where one wire is hot and one wire is cold (neutral). You cannot connect a European 230V appliance directly to US 240V because this would connect a hot wire to the appliance's grounded connection, potentially making the chassis components hot! So, while it is true nothing needs to be done to convert US 240V service to single-phase (because it already is), it is not correct to imply that US 240V can be used where you want 240 volts with one hot and one neutral. This would require an isolation transformer or other approved international voltage converter. For more information see the answer to the Related Question Can you plug a 230V 50Hz appliance into a 240V 60Hz outlet? shown below 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.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
You have 230v 3 phase power can you plug a 230v single phase motor into it?
Any two legs of a three phase system are classed as single phase. So yes a single phase motor will operate when connected. Be sure to use the proper motor protection devices to control the motor.
Can 230VAC single phase supply be used on a circuit that demands 208VAC single phase?
A unit of electrical equipment is designed for operation at a certain voltage - or within a certain range of voltages - i.e for 5 volts, 12 volts, 120 volts. 220 to 240 volts. Originally the UK household alternating current supply voltage was specified at 240 volts or, more precisely, 240 volts RMS +/-6%, running at a frequency of 50Hz.Some time ago, to allow harmonisation across Europe, the specifications were changed to 230 volts RMS +10%/-6%, also running at a frequency of 50Hz.Thus the mains supply voltage will remain within European Union norms (standards) even if it varies between an upper limit of 253 volts and a lower limit of 216.2 volts. So, because 208 volts is lower than the minimum range of a standard 230 volt 50 Hz supply, it is not safe to assume that any equipment which has a rating plate saying that it should be powered from a 208 volts ac supply can be used on a 230V ac supply without causing any damage. Such damage might affect the equipment itself or its surroundings or its "human" users... If the Asker could use the discussion page - by clicking the Open Discussion button shown below this answer - to tell us exactly what the circuit is, which "demands 208VAC single phase", that information would be interesting to know. Then, maybe, a much more helpful answer could then be given here!
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
What voltage you get at home in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
How do you convert 230v single phase stove from England to 220v Canadian voltage?
You should be able to use it as is (assuming the plug matches your outlet). It will just run a little bit cooler at 220 volts vs. 230 volts.
Three phase voltage in india?
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
What is 3 phase voltage in Germany?
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
Why is mains voltage 230V?
Yes 230 volts is classed as single phase but it is not the only single phase voltage. If you take any two legs from a three phase system, the voltage from these legs is also classed as single phase. The 230 volt single phase is the output of a transformer whose primary is one leg of a three phase primary high voltage system. The 230 volt secondary is center tapped to give 115 volts before the tap and 115 volts after the tap, hence the common voltage of 115/230 that is used in North America.
How many amps will a 3 hp motor pull on 230 volts?
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
because all over the world there is an standard rate of voltage
How do you get 1 phase 230V from 3 phase 230V?
I depends on what you are connecting to it but you only need 1 of the phases providing you can get to a neutral
Are single phase 208v and single phase 230v equivalent?
No, not really. 208V is derived from two phases of a 208/120 three phase power system, while 230V (or 240) is a single-phase power system already. Motors and other loads are usually notrated for both voltages, and could be damaged if fed the wrong one. Of course, other devices are rated for both. If so, it will be listed on the nameplate.
