Between 120 VAC and 230 VAC line voltage, the latter is significantly more efficient. To this one can also add the resistive losses from carrying double the amps over the house wiring for the same ...

The theory behind the "strange" voltage numbers like 277v and 208v stem from the way the sine wave of the power produces useful voltages which are approximately the cubed root of the peak voltage. In short, 208, 220, 240 all the same as far as your welder is concerned.

How do you get 208 voltage? The formula is volts times the square root of 3, which happens to be rounded off to 1.732. For 2 lines each carrying 120 volts, the calculation for this is 120 volts times 1.732, and the result is rounded up to 208 volts. That's why we call it a 208 volt three phase circuit, or a 208 volt 3 phase line. In respect to ...

it usually means depending on the terminal wiring connection that the motor will operate satisfactorily at either 208 or 230 volts. This usually means the motor is 3 Phase so you will need to know if you have a 3 Phase service if you are going to operate the motor

208 Volt, 3 Phase Power Supply and Pump Motors . This letter is intended to address the common request for motors on 208V, 3 Phase power supply installations. A 208-230/460 Volt motor has two windings – one for Low Voltage (208-230V) and one for High Voltage (460V), each with a 10% swing. So 230V – 10% = 207V low range. In applications where

Tri-voltage motors (e.g., 208-230/460 volt [V]), are designed to produce rated torque at each voltage, but will slip more and operate hotter at 208 V than at 230 or 460 V. Additionally, some 230/460-V motors are marked “Usable on 208 Volts.” Note that the motor nameplate efficiency is measured at rated voltage and

single-phase power available at 115 volts and at 208 volts. The 208 may seem like a strange voltage but it is very common. The motor with the nameplate of Figure 1 shows the lead connections for operation at 240 volts (low voltage) and at 480 volts (high voltage). Electric motors are rated for operation at such voltages as 115 and 230. These are

A common example is a motor wound for 230 and 460 V (230/460 V) but operable on 208 V. This 208-230/460 V motor will have degraded performance at 208 V. Another common misconception is to request a motor rated at network voltage; for example, at 480 V. The NEMA standard is 460 V. The voltage rating assumes that there is voltage drop from the ...
