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.

∙ 7y agoThe best results would be obtained using a 208VAC to 220VAC step up transformer of the correct ratings. An autotransformer should be fine for this purpose and will be cheaper than a transformer with isolated primary and secondary windings.

∙ 7y agoYes, but the motor will draw a higher current because of the lower voltage. For a 240 volt motor operating on 208 volts increase the motor's full load amps by 10 percent. Also remember to increase the motor's overload current protection by 10% to compensate for the higher current reading.

How is it possible that a chicken rotisserie that uses 208v 3 phase can have a motor that uses 208v?
Two scenarios are that the motor could be a three phase motor. These three phase motors are manufactured in smaller sizes. The other scenario is that the motor is a 208/220 volt single phase motor. It will operate on 208 volts by taking two legs of the three phase supply for its operation.
Can you wire a 3 phase 690 volt delta star motor to 480 volt 3 phase with out harming the motor?
Depends on the motor and the load on that motor. If the motor is loaded to its capacity, it will draw the same amount of power as it would on 690 volts - which will result in ( 690/480 = ) 144% of normal current, which will thermally damage the motor, or will trip overload protection.
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
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.
Will a 208 volt 3 phase generator supply operate a 230 volt 3 phase motor?
Yes, but the motor's horsepower rating will not be reached.

Can you power a three phase motor and a 208 motor on the same circuit?
Yes, with the proper control equipment ahead of the motors.
What is a 100 amp 208 single phase?
That is 20.8 kVa but a 208 v single phase supply is very rare. 208 v is usually three-phase, with 120v between neutral and the live wires.

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 for wire sizing and breaker selection. To answer the question you will need a two pole 15 amp breaker.
How do you plug single phase 208 into three phase 480 commercial power supply?
only use one pole. you should definitely refer to the manufacturer's schematics
What is a 208 three phase?
A 208 v three-phase system has 120 v between each live wire and the neutral. It is used in the USA as an alternative to the 120/240 v single-phase system, offering 50% more power for the same current.

How do you convert 230v to 208 volts single phase?
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.
Will a 208 volt 3 phase generator supply operate a 230 volt 3 phase motor?
Yes, but the motor's horsepower rating will not be reached.
Can you run a 208 volt single-phase computer off 240 volt power?
No. The 1-phase 240 setting on your computer's power supply is for the 240V wall outlets in other countries. The 240 outlets in your home are 2-phase 240.
