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.

What size breaker is required for a 13.8 kw electric heater 3 phase 208 volts?
For a 13.8 kW electric heater at 208 volts, you would need a 3-phase circuit with a minimum of a 50-amp breaker to handle the load safely. This calculation is done by dividing the power (13,800 watts) by the voltage (208 volts) and then dividing by the square root of 3 (since it's a 3-phase system).
How many amps does 30KW strip heater draw at 208 volts 3PH?
Assuming it is a 208-volt line voltage (as normal in 3-phase) the phase voltage is that divided by sqrt(3), or 120 volts. Each phase has to supply 10 kW so the current on each phase is 83.3 amps.
How many amp will a 3 phase 208 volt 10.6 kw heater draw?
To calculate the current (in amps) drawn by a 3-phase heater, you can use the formula: [ \text{Current (I)} = \frac{\text{Power (P)}}{\sqrt{3} \times \text{Voltage (V)}} ] For a 10.6 kW heater at 208 volts, the calculation would be: [ I = \frac{10,600 , \text{W}}{\sqrt{3} \times 208 , \text{V}} \approx 27.8 , \text{amps} ] Thus, the heater will draw approximately 27.8 amps.
Are single phase 208v and single phase 230v equivalent?
No, not really. 208V is derived from two phases of a 208/120 three phase power system, while 230V (or 240) is a single-phase power system already. Motors and other loads are usually notrated for both voltages, and could be damaged if fed the wrong one. Of course, other devices are rated for both. If so, it will be listed on the nameplate.
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.
How is total KWH power usage calculated for a 208 volt 1 phase 60 hertz circuit drawing 24 amps per leg?
Single phase power from a L-L voltage of 208 volts is calc'd: P = V(phase to phase) * I (individual phase current) / sqrt(3) Total power from all three legs is the above P * 3. P is in watts; continuous sampling will result in watt hour measurements; 1000 x this is kWh's.
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.
What ways are there to convert 480 3 Phase to 208 3 phase?
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
How can change voltage from 440 v 3 phase to 208 v 3 phase?
I have 12 amps 208/3/60 what would the amps be @ 440/3
What size breaker is required for a 13.8 kw electric heater 3 phase 208 volts?

This calculation is done by dividing the power (13,800 watts) by the voltage (208 volts) and then dividing by the square root of 3 (since it's a 3-phase system).
Can a 240 volt single phase load connect between the high leg and regular phase leg of delta connected three phase system?
yes but voltage will be out a little.This ok for something like a heater which wont care.But for an electric motor starting and overheating maybe a problem.In the US this would be 220v single phase and 208 volts 3 phase.
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.
How many volts in 3 phase?
It starts out with 480 Volts, which is used to power motors. 480 can be stepped down to 120/208/277. The 120 operates normal appliances, while 208 can be used for dryers and welders rated for 208. 277V is usually used for lighting circuits. 3-Phase is used in commercial and industrial settings.
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.
How many amps does 30KW strip heater draw at 208 volts 3PH?
Assuming it is a 208-volt line voltage (as normal in 3-phase) the phase voltage is that divided by sqrt(3), or 120 volts. Each phase has to supply 10 kW so the current on each phase is 83.3 amps.
What size breaker is used for a 3 horse power motor with 3 phase 208 volts?
I would go with 20 amp 3 pole 15 amp will also do
Will a 208 volt 3 phase generator supply operate a 230 volt 3 phase motor?
Yes, but the motor's horsepower rating will not be reached.
