This should not be a problem but check with the manufacturer of the laundry equipment to be certain.

What happen to 440v motor running at 480v?
Depends on the motor. If it is a synchronous motor it will run too fast.
Is there any advantage of 208V vs 480V three phase?
208 v. equipment is a little smaller and cheaper, and 208v. is slightly safer to use. However, 480v. runs on half the amperage 208v. equipment does, which means equipment or devices cost almost 50% less to operate. With respect to energy consumption, the answer above is incorrect. It is true that equipment that operates at 480v does operate at roughly half the amperage vs. 208v, however, it operates at over twice the voltage. Your local power company charges you per kilowatt hour (voltage x amperage), not on amperage alone. Example, a 208v motor that draws 10 amps would consume (208v x 10a) 2.080 kilowatts per hour. The same motor on 480v would draw roughly half, 4.3 amps (480v x 4.3a) and would also consume 2.080 kilowatts per hour. So in terms of power consumption, they are virtually the same. The main reasons one would opt for higher is the fact that you can install smaller wire and you can run longer distances. It's a ratio that is directly proportional (at least with electric motors/inductive loads). If you were comparing a 240v motor to a 480v motor the ratio would be exact, if a 480v motor draws 5 amps, the same motor on 240v would draw 10 amps.
What is the acceptable voltage higher than 480v for a 480v inverter?
The voltage range should be marked on the case but without that information a 5% increase can be assumed, so 504 v.
A 240V to 480V Step up transformer with a load of 85 amps at 480v what amperage will the transformer draw if the primary is 240V?
Since this transformer has a ratio of 1:2 the load current on the 480V side just has to be doubled. 85 x 2 = 170A on the primary. 40.8 KVA transformer. To prove this just find the KVA of both sides and they should be equal.
Can a 600V rated cable be use in 480V 3 Phase Ckt?
yes,

Depends on the motor. If it is a synchronous motor it will run too fast.
What happen to the 480v rated motoe when connected to 440v power?
Depending on the design of the motor, it may just run with less torque/hp. It might run slightly hotter as well, depending on the load.
What does 277 vac mean?
That's 277 volts of alternating current. This is typically one phase of a 480v 3 phase system. Don't worry that 3 x 277 adds up to more than 480v. A 277v line is typically one phase of a 480v 3 phase system.

Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
How is line voltage computed in a wye three phase cofiguration?
Line voltage equals phase voltage multiplied by the square root of three. a.k.a. E l = E p X 1.73 In a 3 phase 480v system the phase voltage is 277v. Therefore E l = 277 X 1.73 = 480v
How do you convert 380v 3 phase to 220v 3 phase?
Mathematically, just divide 480 by the square root of three. Electrically, 480V refers to the line-to-line value of a three phase system. For example, measure the voltage across A-phase and B-phase and you'll get 480V. 277V is the line-to-neutral value. Measure the voltage across A-phase and the neutral conductor and you should get 277V.
What is the acceptable voltage higher than 480v for a 480v inverter?

Wh would someone divide16.4kva by 480v?
Answer: To determine the amperage in a circuit. Notes: Power (in watts) = Volts * Amps 16.4 KVA = 480V * Amps 16400 / 480 = Amps ~34.2 = Amps
What is the nominal voltage of a 150 kW 480 v generator?
480V.

What are advantages of three phase ac and a single phase ac?
In a typical 3 phase system you have multiple voltages and configurations that can be used in either single phase or 3 phase, depending on how the circuit is designed. A single phase system is just single phase. You can have multiple voltages but it is always single phase.For example, in a typical 277/480v 3 phase system you can power 277v single phase lighting or equipment, 480v single phase lighting or equipment (which uses 2 legs of the 3 phase system but operates like any other single phase circuit), or 480v 3 phase motors.When comparing motors, a 3 phase motor will be substantially smaller than a single phase motor of the same horsepower. You can also reverse a 3 phase motor by switching any 2 leads. A single phase AC motor runs in one direction regardless of how the leads are connected.AnswerFor a given load, a three-phase transmission system requires less volume of copper in terms of conductor size, compared to single phase, so it is more economical to use three-phase.
