208 volts is what is measured when looking at three phases of 120 volt electricity. In three phase electricity, rather than just providing one push of voltage, it provide three rapid pushes of electricity. This allows additional power without the danger of a higher voltage. Unfortunately because it is phased, while some currents are moving in one direction others are moving in the opposite direction. As a result you can not measure the full force the electricity at any one moment in time. The full force would normally be 360 volts [3 phases x 120 volts]. But because of the cancelling out of currents you can only measure the root mean square of the voltage at any moment in time. That would be the square root of the number of phases multiplied by the voltage [squareroot (3) x 120 volts] which equal 208 volts.

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.
Amp meter is showing 208 volts I need 240 volts?
There is some equipment that will operate on 208 volts even though it is rated to be use 240 volts.See discuss question below.
What is the kilowatt output of an electric heater that has an ampere draw of 50 a and a voltage source of 208 volts?
The watts is the volts times the amps So 208 x 50 watts, or 10.4 kW.
What if the input power is 208 volts line to line two phase 8 amps to a heating element vs 110 volts 8 amps to a heating element How is watts calculated?
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts
What is the maximum volts that can be used on a 208 230 volt motor?
You should not go above 240 volts for that type of motor.

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.
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.
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.
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 if the input power is 208 volts line to line two phase 8 amps to a heating element vs 110 volts 8 amps to a heating element How is watts calculated?
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts
Can you operate a 208 volt on 110 volt?
The United States is one of the only places in the world that uses 110 volts instead 220 volts. In order to operate 208 volts on a 110 volt electrical current, you will need a voltage converter.
Does a 208 volt outlet need a neutral?
No a 208 volt outlet does not need a neutral. 208 volts is the line voltage between any two legs of a three phase 208 volt system.
What is the maximum volts that can be used on a 208 230 volt motor?
You should not go above 240 volts for that type of motor.
What is the standard voltage?
In the USA it is usually 120/208 or 120/240 volts In Europe I think it's 220 volts
How do you covert 120 volts to 208 volts?
Single phase or three phase? 120/208 would be measured hot to ground for 120 and hot to hot (phase to phase) for the 208 reading. Any hot to ground will read 120 and any two phases together will read 208.
