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 many amps does 42kw in a 3 phase system 120208 convert to?
You would use the 208 voltage which is a three phase voltage, the 120 volts is each leg to ground or star point. The formula for Amps = kw x 1000/1.73 x Volts x pf. Pf = power factor.
How many amps does a 208 volt 3 phase 45 kw hot water heater draw?
45000 / 208 /sqrt(3) = 125A per phase this is probably called a boiler unless it has a 2000Gallon tank
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 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 is considered high voltage in a 3 phase system?
There are two aspects to consider: 1. There are several different standard voltages and connections used by the power company in three phase service. 2. Depends if the voltage is measured phase-to-phase or phase-to-ground/neutral. The three phase-to-phase (A-B, B-C, C-A) voltages should be roughly equal. In typical service, they may be 208V or 240V. The phase-to-neutral voltages are sometimes intentionally different. For example, some 3-phase service has a "high leg" that is 208 volts with respect to ground (called a 3 phase high leg delta connection), while the other two legs are 120V with respect to ground, so that you can operate 120V, 240V and 3-phase loads from the same utility service. The important thing is you should always measure before connecting equipment. 208V will fry most 120V electronics.
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
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.

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
