The amperage input of a transformer on a 208V three-phase system can be calculated using the formula: Amperage (A) = Power (Watts) / (Voltage (V) x √3). To determine the amperage, you need to know the power rating of the transformer in watts (or kilowatts). Once you have that, you can plug the values into the formula to find the input amperage.

How do you convert 120VAC 60Hz to 208 230 1 Phase?
you need a step up transformer
Can you use 220 Volt 3 Phase as 208 Volt 3 Phase?
Yes by using a 3-phase transformer. The size depends on how much power has to be converted.
Is home electricity 3 phase?
No, in North America most homes are wired to a single phase transformer. That transformer is connected to a three phase power grid. Some of the newer apartment buildings and condominium complexes have three phase systems in them. Their voltages are 120/208 as compared to a homes single phase connection of 120/240 volts.AnswerSome European countries, such as here in Cyprus, have three-phase residential supplies as standard for some reason -can't quite figure out why it should be necessary, though!

Can you convert 240V 3 phase to 208V 3 phase?
Yes, with an auto transformer. It is a transformer with multiple taps on the winding. Connect the 208 volts across the common tap and 208 volt tap. Then connect the load across the common tap and the 240 volt tap.208 VAC usually comes from one floating side of a Delta 3 phase transformer.240 VAC usually comes from a grounded center tapped transformer.Using an autotransformer would be very hazardous and violate code. Probably tripping the 208 VAC breakers.The only way to do it correctly would be with a transformer with a 208 VAC floating primary and a 240 VAC grounded center tapped secondary.
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
How many amps does a 208 volt 3 phase 45 kw hot water heater draw?
To calculate the amperage, you can use the formula: Amps = (kW × 1000) / (√3 × Volts). Plugging in the values, we get: Amps = (45 × 1000) / (√3 × 208) ≈ 131.1 amps. So, the hot water heater would draw approximately 131.1 amps.

45 kva at 208 120 volts amp load?
I am assuming that you are talking single phase. 45 kva is k = 1000, v = volts, a = amps. 45 kva is 45000 volt / amps. Input 45000 divided by 208 volts = 216 amps. Output 45000 divided by 120 volts = 375 amps. There are other losses in the transformer but as a general rule of thumb this is the calculation that you would use.
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.
Can you use 220 Volt 3 Phase as 208 Volt 3 Phase?
Yes by using a 3-phase transformer. The size depends on how much power has to be converted.
Can you convert 1 phase to 3 phases?
You can buy a converter. Here is one example of many available on the web.Phase-A-Matic PAM-300HD Phase Converter, Static, 1-3 HPPhase Converter, Static, Input Voltage 208-242, Output Voltage 208-242, Input Phase AC 1, Output Phase AC 3, Input (Amps) 15, Output Amps 9.6 ...
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.
Can you use 600VOLT motor in 220VOLT supply through a transformer?
Usually with a voltage of 600 volts the motor will be three phase. To use a transformer with that motor you will need a three phase 240 volt service. These days utility companies are moving away from three phase 240 and substituting it with 120/208. The 208 three phase service has the added bonus that 120 volts can be obtained from the star point (grounded neutral).

What is the output current of a 480 Volt primary 208 volt secondary - 3 phase transformer?
You need to mention the Load connected to find the current.
