I just returned from a Square D Conference, where I joked with them about this dumb idea that GE has of using a 133% fan cooled rating to achieve the required values for a project.
They seemed nervous and told me that they didn't think it was so dumb. So look out in a few months, because even SquareD (Schneider) will have fan cooled xfmrs as a standard product. [Linked Image]
You can specifically order them without fans if speced that way.
