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 do you convert 120VAC 60Hz to 208 230 1 Phase?

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.


What is a 100 amp 208 single phase?

That is 20.8 kVa but a 208 v single phase supply is very rare. 208 v is usually three-phase, with 120v between neutral and the live wires.


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.


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 can change voltage from 440 v 3 phase to 208 v 3 phase?

What is 208 - 230 volt three phase?

In the United States, 208v can be either. It is generally the voltage supplied by a 120/208v 3 phase system. However, using 2 legs of this 3 phase system is called single phase. I won't go into the reasons for that but just understand that 208v can be either single phase or 3 phase.


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.


What are the specific electrical requirements for a device that operates on 208 volts single phase power?

A device that operates on 208 volts single phase power requires a power source that provides 208 volts of electricity in a single phase. It is important to ensure that the device is compatible with this specific voltage to prevent damage or malfunction.


Can you buy a converter to connect to 240 single phase and convert it to 208 3 phase for electric grill?

If you mean by a converter, a transformer, to change the voltages then yes 240 volts can be transformed with a step down transformer from 240 volts to 208 volts in a single phase system. To answer the question single phase can not be converted to three phase without additional expensive equipment. One piece of equipment that will do it is a variable frequency drive. Another piece of equipment is a roto-phase. Either of these pieces of equipment would probably cost more than the grill you are trying to supply a voltage to.


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 120 volts 1 phase into 208 volts 3 phase 40 amps per phase and would it be cheaper to get 208 volts 40 amps per phase installed in your house by electrician?

Answer for USA, Canada and countries running a 60 Hz supply service.To answer the first part of the question. No you can not convert 120 volts single phase into 208 volts 3 phase. In fact it is the other way around, the 120 volts is the line to ground (neutral) of a three phase 208 volt system.The second part of the question is dependant on there being a three phase 208 volt system already installed. To obtain 40 amps per phase would require a three pole breaker to be installed in a 120/208 three phase distribution panel.The distribution panel would most likely be in the 100 to 200 amp capacity range. This kind of installation would definitely have to be installed by an electrical contractor as inspections and permits would have to be taken out for the project.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
