# Can you use a 230 Volt 1 phase motor with 208 volt 1 phase?

230 V is the standard nominal voltage in the UK. 'Nominal' means the 'stated' voltage, but this is allowed to vary, under government legislation, between +10% and -6%, which means it is allowed to drop to 216 V.

The motor's rated voltage of 208 V is *also* a nominal
voltage, but is not a standard UK nominal voltage so, without
knowing what in which country the motor is manufactured, we'll
assume that it is allowed to vary between, say, +5% to -5%. This
means that it can operate at voltages up to 218 V. If it's allowed
to vary between, say, +10% and -10%, then it can be operated up to
229 V.

So there is an overlap between the nominal voltage of the supply and the rated nominal voltage of the motor so, in all likelihood, the motor should be able to run with a 230-V supply. On the other hand, there will be times when the supply voltage will exceed the upper limit of the motor's nominal voltage, and this may -over time- lead to a breakdown in its insulation and its ultimate failure.

### What is the difference between 208 volt and 220 volt power?

The main difference between the two voltages is that the 208 volts is a three phase voltage and 220 volts in North America is a single phase voltage. If you operate a 220 volt motor on 208 volts the current will be 5% higher that the motor's nameplate rating. If the load is resistive and you operate a 220 volt baseboard heater on 208 volts the true heater wattage will not be reached because of…

### What size breaker for a 208 volt single phase motor that pulls 1.4 amps?

208 volts is not a common single phase voltage but you could just size your breaker to the capabilities of the conductor. 208 is normally a phase to phase voltage <<>> Many 230 volt motors can be connected to lower voltage supplies. These motors can be connected to supplies of 208 and 200 volts. The code requirement is that the 230 volt full load amperage of the motor be increased by 10% and 15% respectively…

### Can two phase legs on a three phase system be used for single phase load?

The wire can be used for dc or any number of phases provided it's thick enough to take the current you need. <<>> Any two legs of a three phase system can be classed a single phase. As long as the voltage required by the load is supplied by the supply it can be connected. A perfect example of this is on a 120/208 volt supply. This is a three phase supply allowing three phase…

### Can you use 240 volt single phase to run a 208 volt single phase motor?

This is a 15% overvoltage to the motor, which is generally outside the specifications for a motor spec'd at 208v (typically up to 10% overvoltage is tolerable). Your 240 volt source may be as much as 105% of 240 / 252 volts at times. A buck/boost transformer should be used, unless the motor is designed to be used at 240 volts.

### Can 1 phase be used with 3 phase?

If you have a 208Y/120 volt 3 phase system, you can use any one of the three phases (hot or ungrounded conductor) with the neutral for 120 volt load or you can use any two phases of the three phase for a single phase 208 volt load. If you have a 120/240 volt 3 phase system, you can use any two phases of the three phase for a single phase 240 volt load or you…

### Can you convert 240 volt to 208 volt?

I'm sure you could, but it wouldn't be practical. The reason for this is because 208 volts between two phases comes from a three phase transformer, while 240 volts phase to phase comes from a single phase, center tapped transformer. If you're asking regarding a resistive load, such as a heater, the load should work with 240 volts or 208 volts. There will be a slight difference in performance, but it shouldn't be very noticeable…

### How is it possible that a chicken rotisserie that uses 208v 3 phase can have a motor that uses 208v?

### How many Amps for 3 horsepower at 208 volts?

For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.

### What is a 208 circuit?

The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases. 208 circuit would consist of two phases of a 208 volt wye system or could be all three…

### Can a 230 volt electric motor run on 208 volts?

Yes, a 230 volt electric motor can run on 208 volts. The horsepower will be lowered by .9 or to 90% of the nameplate rating. e.g. A 230 volt 10 HP motor will only produce 9 HP at 208 volts. Note: If motor sees a load equal to its' rated HP it will over amp and shorten the live of the motor and/or trip out on internal overload.

### Is it possible to hook up a unit that is 208 volt single phase to a 240 volts 3 phase?

Any two legs of a three phase system are classed as single phase. If a 208 volt device is connected across two legs of a 240 volt system its current draw will be higher. It is not recommended to connect a 208 volt device to a 240 volt supply. Using a constant resistive load of 6000 watts for an example, the resistance of the unit at 208 volts has to be found. R = E…

### Can a 208 volt be the same as 220 volts?

208 can never be the same as 220 but some appliances would be able to work with a range of voltages that includes 208 v and 220 v. The voltage should be marked on the appliance. <<>> A 220 volt single phase motor can operate on 208 volts but the overload protection has to be increased by 10% because of the lower voltage causes a higher amperage draw.

### Can you use 600VOLT motor in 220VOLT supply through a transformer?

Usually with a voltage of 600 volts the motor will be three phase. To use a transformer with that motor you will need a three phase 240 volt service. These days utility companies are moving away from three phase 240 and substituting it with 120/208. The 208 three phase service has the added bonus that 120 volts can be obtained from the star point (grounded neutral).

### Can you step up 208 volt to 380-440 volts is it cheaper to have the washer converted or use a step up transformer?

You didn't mention whether the voltages are single phase or three phase or whether it is a commercial machine or one used in the home. I am assuming that you are asking about a single phase washer. That being said yes, 208 volts can be stepped up to 440 volts. To have the washer converted would mean finding a 440 single phase motor with the identical frame type that would fit the same configuration that…

### You have three phase power and you have a motor that needs 208 volts can you conectt it to the line carries 208 only?

If your appliance or motor is asking for 208 volt, it usually means that it also wants 3 phase. If you measure the voltage between the hots on a 3 phase feed, you will find that it is somewhere around 208v. As long as you connect it to the 2 or 3 hots that you measured, then you will be fine. Make sure you ground, and no neutral should be present.

### What is the difference between single phase and three phase voltage measurement?

Phasing, or the number of phases in an electrical system has nothing to do with the voltage. A single phase and three phase supply could have a voltage supply of any given voltage from virtually 0 to infinity. Most single phase power supplies in the US are 120/208-240 volt. Three phase power supplies are typically 120/208 to 277/480 volt.
