The company I work for hired some guys to install a new panel for new equipment. So they pulled 400amps 3phase from our engine room. They ran it to a 400amp panel, then fed a transformer with a 100amp breaker to feed a 200amp 208v panel.
Now we have 130v to our 120v receptacles and the 480v machines are either real slow or extremely fast. Plus they will shock you if you touch them. Any ideas? I'm guessing no neutral.
