I am a little confused on a situation that I ran across the other day. The garage where I work has a "240 volt three phase" service. It measures L-G 120,208,120 and L-L 240. Is this considered a 208Y120?.
The issue is that I have a 115/230 vac single phase chop saw that is "custom" wired. It has a 2 conductor cord on it, plugged into this 3 phase 4 wire service. They have one conductor to the ground pin and the other to the 208 pin. I don't have a wiring diagram for this motor so I'm not sure exactly how this is. If I remember correctly, it has 4 wires in the motor. The green wire in the motor is connected to the ground pin on the cord. One wire is connected to the 208 pin. And two others are tied together.
Can anyone help me with this confusion? How is this working? I know its not right and I want to fix it correctly.
Thanks, Merlin
