# Can 208 3 phase be changed to 460 3 phase?

Yes by using a 3-phase transformer. The size depends on how much power has to be converted.

### How do you measure 3 phase voltage?

Three phase voltage can be measure line to line (L1-L2, L2-L3, or L1-L3) with a quality digital voltmeter. In the United States, typical 3 phase voltage is 208-230VAC, or 460-480VAC measured line to line. Line to ground or neutral with a 208-230V system will yield 110-120VAC, which provides standard household power for things like televisions and microwave ovens.

### How does 120 volts come from 208 volts?

208 is a three phase wye connection voltage. To obtain the each individual coil voltage the 208 is divided by 1.73 which equals to 120 volts. Hence you have 3 phase 208 voltage on the phase legs and 120 volts to the wye point which is grounded. This same formula is used on any 3 phase system. 600/347, 480/277, 208/120.

### What is the phase to phase voltage on a 208 3 phase panel?

Phase to phase voltage on a 3 phase 208 volt panel is 208 volts. From each of the three phase legs to the starpoint neutral the voltage is 120 volts. Correction to the above answer. phse to phase means the line to line voltage. phase voltage is another thing. phase to phase voltage is equal to root 3 times phase voltage. PHASE TO PHASE V = 1.73 * PHASE V The correct term is 'line-to-line'…

### Which leg is 208 on 3 phase power?

On three phase 208 volts one leg does not have the potential of 208 volts. It takes two legs to provide the 208 volts. The potential is across AB, BC and CA. Voltage to the grounded neutral A-N, B-N and C-N will produce a potential of 120 volts. In a wye configured secondary three phase four wire you have the potential of 120/208 volts.

### 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.

### What is the measured Voltage between L1 and Earth on 3 phase system?

Wouldn't this depend on the voltage of the system? Like if it is a 460 or 208v system it would be 208 or 460v. There should be 3 lines L1 L2 and L3 all measure the input voltage. The wye or star point voltage on a three phase system is the square root of three. This number (1.73) is divided into the three phase voltage to get the voltage to neutral (ground). 208/1.73 = 120…

### On a 208 120 volt 3 phase electrical system what is the color code for the wires?

208/120 is typical for the US, so these are the colors for the US: A phase: black -------------------In Canada; A phase - Red B phase: red-------------------------------------B phase - Black C phase: blue -----------------------------------C phase - Blue neutral: white -----------------------------------neutral: white ground: green or green with yellow stripe

### How will a 3 phase panel give you 110 volts and 220 volts?

A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.

### Can 1 phase be used with 3 phase?

If you have a 208Y/120 volt 3 phase system, you can use any one of the three phases (hot or ungrounded conductor) with the neutral for 120 volt load or you can use any two phases of the three phase for a single phase 208 volt load. If you have a 120/240 volt 3 phase system, you can use any two phases of the three phase for a single phase 240 volt load or you…

### How is it possible that a chicken rotisserie that uses 208v 3 phase can have a motor that uses 208v?

### Is 277 volt and 277 volt equals 460 volt?

No, voltages in a wye configuration are not additive. Calculations for wye connection used the nominal voltage of 480 volts. The voltage of 277 volts is derived from the the phase voltage of 480 divided by the square root of 3 (for three phase) . 480 / 1.73 = 277 volts. For phase voltage of 460 the coil voltage to ground will be 460/1.73 = 266 volts.

### What is the typical 460 3 phase voltage 1 leg to ground?

230v 230v In a transformer with a primary connected to 480V Delta and a secondary connected in 480V Star connection, the coil voltages to the star point (ground) are 277 volts 480 / 1.73 = 277 volts. Other star connections are 208/120 (208/1.73 = 120V), 600/347 (600/1.73 = 347V). Because the phase angles are not 180 degrees apart they are not additive, they are 120 degrees apart which is why 1.73 factor comes into play.

### What is the voltage in a three phase electrical supplies?

The line-to-line voltage (line voltage) is the square-root of 3 higher than the line-to-neutral (phase voltage) voltage. So, if the phase voltage is 220 V, then the line voltage must be 381 V. <<>> Common North American three phase voltages are 120/208, 277/480 and 347/600. The sq. root of three is 1.73. By applying the method in the first answer's formula - 120 (phase to neutral or ground) volts x 1.73 = 208 (phase to…

### I have a piece of equipment that the states the voltage required is 208-240 Vac single phase. Is 208 volts from a 120 3 phase system the same as 120-240 volt single phase?

You have it around the wrong way. 120 volts is from a three phase 208 voltage system. 208 divided by the root of 3 (1.73) equals 120 volts. A 208 voltage distribution system is a wye connection that has its center point tied together and grounded. Any three legs of the wye configuration to the grounded center point will give you 120 volts. Any two legs of a three phase system are classed as single…

### How many Amps for 3 horsepower at 208 volts?

For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
