How do you run a motor 208 volts ac in a 230 volts suply?
If your motor is rated for only 208 volts you may not be able to use 230 volts for it. It will run, but may shorten the life of the motor. Motors are rated with a 10% tolerance for voltage. This means that a 208 volt motor has a maximum voltage rating of 228.8 volts. So measure you voltage supply and see if it is below 228.8 with a good RMS voltmeter. If it is, you are good to go. If it is not there are two ways to make it work. 1. Put a high wattage ballast resister in series with the supply voltage to drop the voltage to the motor within range of 187.2 to 228.8 volts. To determine the value of the resistor take the Horse Power of the motor and multiply it by 746. This will give the wattage of the resistor, use one at least 20% larger. Next take the Rated Load Amps (RLA) or Full Load Amps (FLA) of the motor and divide it into the difference between 230 (voltage supply) and the 208 (rated motor voltage), this will get you close to the resistance value of the Ballast resistor you need to use. So a 1/2 HP motor with a 1.2 RLA will require about a 18 ohm, 500 watt ballast resistor. This is not the recommended method, but will work. 2. Install a Buck & Boost transformer rate for the HP of the motor that will Buck the supply voltage for the motor down to 208 volts. This is the recommended way and the only way it should be done. Any good commercial electrical supply house can help you properly size the transformer that you will need.
Why does star connected motor run at less amps?
In star, a motor is connected with 415V across 2 phases, which means Line voltage is 240V (415 / 1.7ish) In delta theres 415 across each phase, therefore I = much higher according to Ohms law (I = V/R) Hypothetically; load of 24ohms connected on the motor In star; I = 240 / 24 = 10A In delta I = 415 / 24 = 17.2A Hope this helps a little
Will a 3 phase generator at 6kva run a 3 phase mincer 50 hz 415?
No it will not run
Can a 230-460 volt motor be connected to a 120-208 volt circuit?
Yes it will run. That said you will be shortening the life of the motor due to the excessive heat generated at the higher voltage. The insulation of the motor winding is related to the voltage that is applied to the motor. With excessive heat comes insulation breakdown. Once the insulation breaks down, the winding will start to short circuit. With a short circuit on the motor winding copper wire is lost. Think of a welder when an arc is struck. Once this happens to a motor it becomes non operational and a rewind is the only way that the motor is going to become operational again.Install a Buck & Boost transformer rate for the HP of the motor that will Buck the supply voltage for the motor down to 230 volts. This is the recommended way and the only way it should be done.

Are there tri-voltage motors?
On some motor nameplates you may see 120/208-240. These are not true tri-voltage motors. They are dual voltage motors with a leniency on the 240 volt range to be derated to run on 208 volts. At this voltage the current drops and you don't get the full horse power rating of the motor. To answer your question I have never seen one that would do true three voltages like 120/240/480.
Can you hook up 208 volts on a 230 volt motor?
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.
Will 10 hp motor run with 230 volt?
no
230 volt motor be rewired to run on 208 volts?
Check the manufacturer's spec. You might be able to get away with this. Beware though, a reduced source voltage will manifest itself in a higher current draw, which results in an increase in heating.

Is an airconditioning unit labeled to run on 208 vac to 230 vac ok to run on 240 vac?
yes, UL listing requires them to work with tolerance of 10% over equipment voltage
Which A motor is to be operated from 230 V 50 HZ single phase AC?
All types of motor can be run from a single-phase supply provided the frequency, voltage and power capacity of the supply matches that of the motor and it has been designed to run on single-phase.
Should i Run pump on 115 or 230 volts?
That depends on what the suply is if your power suply is 230 then you run it on 230.

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 minimum volts that can be run on a 220 line?
depends on what the line is feeding. 220, 225, 230, 240, even 250 are all in the same catagory. power companies have increased their output voltages through the years. i would say 220 is minimum. if your connected load is a motor, they are more voltage sensitive, and should be run on 230 or 240. it makes the motor more effecient
30 amp 230 VAC circuit can you run a 5 hp motor?
This answer depends on the characteristics of the motor. There are may different applications for motors and though the HP remains the same, the full load amps differ. If you have the FLA of the 5 HP motor then an answer can be given.
