The 240 to 480 Step-up Transformer To get from 240-volt 1-phase power to 480-volt 3-phase power, you need a step-up transformer that is manufactured to the proper specifications to handle this task. These are available online or at electrical supply stores. To get from 240-volt 1-phase power to 480-volt 3-phase power3-phase powerThe conductors between a voltage source and a load are called lines, and the voltage between any two lines is called line voltage. The voltage measured between any line and neutral is called phase voltage. For example, for a 208/120 volt service, the line voltage is 208 Volts, and the phase voltage is 120 Volts.https://en.wikipedia.org › wiki › Three-phase_electric_powerThree-phase electric power - Wikipedia, you need a step-up transformer that is manufactured to the proper specifications to handle this task.

What size step up transformer do I need?
Knowing you need 57.2 amps (I) and the output of 480 volts (E) Watt's law can be applied as P = I x E. Therefore, 57.2 x 480 = 27,456 watts, or 27.456 KVA. This would be the minimum size transformer required for this application.
What is the difference between 208 and 480 volt?
208V is the voltage between phases of a 3-phase “Y” circuit that is 120V from neutral to any hot. 480V is the voltage between phases of a 3-phase “Y” circuit that's 277V from hot to neutral.208V is the voltage between phases of a 3-phase3-phaseThe conductors between a voltage source and a load are called lines, and the voltage between any two lines is called line voltage.

Can you get 120V from 480V?
The ratio of 480V to 120V is 4:1.16 Apr 2008

How do you get 208V from 3 phase?
The formula is volts times the square root of 3, which happens to be rounded off to 1.732. For 2 lines each carrying 120 volts, the calculation for this is 120 volts times 1.732, and the result is rounded up to 208 volts. That's why we call it a 208 volt three-phase circuit, or a 208 volt 3 phase line.
Can you get 240v single-phase from 480V 3 phase?
Yes if you have a stepdown transformer you either need a 480÷√3 (480÷1.73) =. 277.46 volts AC input —208 or 240 volts AC output transformer assuming a neutral (PHASE voltage) supply is available.

How do I know if I have Delta or Wye?
The Delta configuration has the three phases connected like a triangle. Delta systems have four wires total: three hot wires and one ground wire. Wye systems utilize a star configuration, with all three hot wires connected at a single neutral point.31 Oct 2013
What is the difference between 480 Delta and 480 Wye?
The difference is that the 480 wye breakers are rated 480/277 volts and can only be used on systems with a maximum voltage to ground of 277 volts. The delta breakers are for use on a grounded phase system or an ungrounded system and are rated for 480 volts to ground.31 Aug 2011
