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.
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.
What is the typical 460 3 phase voltage 1 leg to ground?
230v 230v In a transformer with a primary connected to 480V Delta and a secondary connected in 480V Star connection, the coil voltages to the star point (ground) are 277 volts 480 / 1.73 = 277 volts. Other star connections are 208/120 (208/1.73 = 120V), 600/347 (600/1.73 = 347V). Because the phase angles are not 180 degrees apart they are not additive, they are 120 degrees apart which is why 1.73 factor comes into play.
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.
What is the standard European household voltage and ampreage?
Europe is a collection of independent nations, many of whom have fought eash other bitterly since records began!!!! The voltage varies between 210 and 240 volts 50HZ. I am in the UK, and our voltage is stated as 230, but is usually measured as closer to 240. The average modern house has a 100Amp service coming in from the electricity supplier. Older properties may only have a 63A service. In continental Europe, certainly the western part, the voltage varies between 220 and 230, but I do not know what the maximum amperage is. I would suspect it is similar to that in the UK. The former eastern bloc countries have standardised on 220/230v but you will still find some "strange" installations, especially off the tourist trail. Note that all the voltages stated are single-phase, or live conductor to ground. Split phase, or 2-phase to give 120/220v is *very* uncommon is Europe. Three phase in Europe is (nominally) 400v phase to phase or 230v phase to neutral
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 is 3 phase voltage in Germany?
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
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 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.
How do you connect 3 phase inverter to single phase supply?
It depends on the 3 phase inverter. If it is a 3 phase input then you will first need to get a single phase to 3 phase converter to simulate a 3 phase supply, if that is what this particular inverter is intended for then you will have a label saying 230v primary with a L & N connection point, and the output will be labelled as secondary, giving you the inverted power rating. This is a very expensive way of running machinery as the inverted power is no different in conumption to the single phase.
What are the advantages of using a three-phase system over a single phase system?
For the info. of everybody..... the 3-phase system is definitely use in large commercial & industrial plant that uses large equipment/apparatus, like motors powered by more than 230v supply. However, single-phase system was commonly used in residential, which uses 230V or 110V equipment/apparatus, also considered as light load....

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 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
Can use 400VAC 3-Ph industrial socket on 230VAC 3-pH supply?
The common European supply voltage is 400 v three-phase. That is the voltage between live lines, and there is 230 v between neutral and each live line. A 230v three-phase supply would have 173 volts from live to neutral and that kind of supply is extremely rare.
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.
What does the terminology - 240 volt 3 wire - mean?
European domestic supplies are 230v single-phase, derived from a 400 v three-phase supply running down the street (usually underground). This supply is a 4-wire system with three lives and a neutral, which it must be because the different properties draw different currents. When the system is working well the current drawn by a group of houses are reasonably well balanced across the three phases.
Can European 380 V 50 Hertz machinery be used in the US?
Strictly speaking, yes. All you need is to supply a 380V / 50Hz three phase power supply (three phases at 120 degrees, possible also a neutral point, depending on the machinery).In simply and everyday terms, since most US standard power outlets supply a single phase at 120V and 60Hz, you cannot use European 380V 50Hz machinery without extra circuitry.Wait, there's more:a) First, note that present-day European systems supply 230V (single phase) or 230*sqrt(3)=400V (three phase). The 380 V system has been upgraded when the main (single-phase) voltage was upgraded from 220 to 230V some years ago.b) Some US premises sport 240V / 60Hz power supplies for heavy duty use. I believe this is a single-phase supply, used with machinery, air-conditioning units, etc. If this was the case, then you might be able to connect a European piece of machinery with small extra cost, subject to unit's power rating and phase shift tolerance. To do so, you would implement what is known as a Steinmetz-Connection. if you can read simple formula and schematics, you should be able to figure it out from the German language Wikipedia article; see related links.The difference between 240V and 230V is less than 5%. Any piece of electrical equipment will tolerate 5% higher than nominal supply.
