8. Any voltage can be supplied as three-phase. Various voltages are more popular in various parts of the world and in various usage situations. In the USA, 220-240 volt, three-phase has been used to some extent for small industrial installations, but 480 volts is much more popular for three-phase installations. Share. The first step is to make sure that the three-phase supply line is grounded. This will prevent the power from sagging, which could be hazardous. Before attempting a 3-phase to single-phase 220v conversion, you’ll need to consider how your machine is wired and how the current balance needs to be.
Input supply voltage. (Mandatory) Motor Efficiency as per nameplate – (if known). Rated power factor (if known). After entering the required data, click on the “Calculate” button to find out the required fuse rating, Circuit Breaker rating, contactor current rating, and overload setting. The appropriate selection of fuses, circuit

Here is the first of two videos about how to re-wire a three phase motor to change it from 480 volt to 230. Also, since this is three phase equipment, I cov
