I bought an Index mill which has a 220/440 three phase motor on it. It also has a "ThreePhaser Model 1000" converter box on it. I don't have any docs on it but is is wired already. Problem is that it has a 110V 20amp plug on it. (looks like a regular 110 plug except one blade is rotated 90 degrees) I'm guessing that someone used that for 220 volts so that it couldn't plug into a regular outlet. I assume that I need a line voltage of 220 since there is transformer in the converter. I plan on installing a 220V 40amp circuit to it if I am right. So does that sound like someone just used the wrong plug on it? If anyone has any ThreePhaser docs that would be great!
