∙ 12y agoA 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.

no 208v is bigger
No.It'll overload and fail just about immediately.It's possible - but not recommended - to run two 110 v heaters in series from a 220v circuit.
400 amps
Answer for USA, Canada and countries running a 60 Hz supply service.Assuming you are using the same fixture, and assuming the fixture can operate on either voltage, you will get fewer amps with 208v than with 277v. However, a fixture designed for 208v will probably burn up on 277v, and a fixture designed for 277v will probably not produce any light on 208v.The two fixtures in reality are quite different. The 277v fixture is using one leg and neutral of a 277/480v 3 phase 4 wire system and the 208v fixture is using 2 legs of a 120/208v 3 phase 4 wire system.In commercial and industrial installations the 277v fixture is most common.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.

No, you only have phase a and b. The motor will run as smoothly as a 3 phase motor that has lost a leg of power. That is if the motor is designed for 208v in the first place. Not a good idea.
if you are using the pressure switch to control a 3phase pump chances are it already has a magnetic starter and a single pole control circuit i have seen small 3phase air compressors with the contacts driven right off the diaphragm bigger ones usually have 110 volt controls i would be concerned about the current rating of the switch if you are trying to switch the motor directly there are many single phase compressors that run directly from the pressure switch
Clamp the meter around the energized conductor that is connected to the load to be measured and read the amperage off of the dial face of the meter.
To convert from kilowatts (kW) to amps in a 3-phase system, we need to know the system voltage. Using the formula: Amps = (kW x 1000) / (√3 x Volts), where √3 is the square root of 3. Assuming a system voltage of 120/208V, the amperage would be approximately 135.1 amps.
It is not recommended to connect a 240V ballast to a 208V line service as this can potentially damage the ballast and create a safety hazard. It is best to use a ballast that is specifically designed for use with a 208V line service to ensure safe and proper operation.

Its on the specifications of the device you will plug
