Hi fellas. I am currently installing a machine from China, it came to the US in about 30 crates, and complete with a Chinese electrician to "help" me install it. First, the chinese know nothing about conduit or wireway, he just wants to run wire across the floor to each motor. Second, the machine work sucks, I am not even sure the thing will work when we are through. Now to my question: The voltage in the plant where we are installing this beast is 480Y 277 3 phase 4 wire, and one of the cabinets for controlling a scale needs 480v and 120v inputs. My Chinese helper has said thru his interpeter that in China he could grab one leg of the 480v and the Neutral and have 120v, he then drew it out like a star configuration. Question, is it possible to get 110v out of a 480v star system? I am going pull a 120v feed from another panel, just wondering if this would work as someone said the scale panels were burnt up and had to be repaired while the machine was being run in China. Your thoughts.
