Most technical people believe that AC electricity is not polarized this is an incorrect assumption. Since AC power is just a potential difference between some reference (ground) and a signal it stands to reason reversing the Neutral and the "Hot" should reverse the polarity.

Can you use 240 volt 3 phase to run a machine that is 240 volt single phase?
Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
Can a standard 40 amp 208-240 volt single phase oven be wired to a 240 volt three phase circuit without using a transformer?
See Discussion Page
Will it hurt 230 volt single phase motor plugged into 277 V single phase?
The safe operating range of the motor should be printed somewhere on the exterior of the motor.
How do you convert 277v to 120v for an outlet?
i think you just have to change the breaker from a 277 to a 120. 277 breakers are usually a 2 pole breaker and 120 is a single pole breaker. NO. 277v is not two poles, it is one pole, one single pole breaker in a 480 volt 3 phase system (typically). If you want 120 volts from a 277 volt source you need a step down transformer 277 volt to 120 volt , or 480/277 to 120/208 .
Is the nortron wheel balancer 110volts or 220volts?
The standard units were 220 volt, 3 phase. 220 single phase was a purchase option. There were also conversion kits to convert the machines from 3 phase to single phase. The kits contained a 1 HP 220 volt capacitor start motor and a DC motor brake control assembly. Jerry S greentron@att.net
How do you change a 3 phase 440 volt motor to a 3 phase 220 volt motor?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
In a 240 volt single phase circuit A phase is 4000 watts B phase is 7000 watts what is the neutral load?
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
Is there a single phase 460 volt variable speed control?
No you need a Roto Phase
Can a 230 volt single phase watt hour meter be used to monitor 115 volt single phase?
Yes it would work pretty well but it might not meet its accuracy specification.
What is the ac equivalent of 98v DC?
120 volt single phase rectifies to about 96 volt DC
How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
What transformer do you need if you have primary voltage of 600 3 phase and require 240 volt 1 phase?
A single phase 600 to 240 Volt transformer using two phases of the three phase primary.
Can you use 240 volt 3 phase to run a machine that is 240 volt single phase?
Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
How do you get single phase 440 from three phase 440?
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
Does a 2 horsepower rotary converter plug into 120 single phase and convert it to plug in a 3 phase outlet?
All my experience with rotary phase converters have been in converting 240 volt single phase into 240 volt three phase. They all were hard wired into their respective systems, so my answer is no.
What is the voltage for Sweden?
Outlet for standard electronics is 230 Volt , 50HzThe master feed into Swedish houses is 400 Volt three-phase , 50Hz.When 400 Volt three-phase is split in three single phases it becomes threesingle 230 VoltBigger appliances , e.g Washing-machines, dryers, stoves, used to be400 Volt three-phase, but nowadays most washing-machines and dryersare built for 230 Volt single-phase.
