[BC] Re: Saving Your Own Life

[Milton R. Holladay Jr.]

One of the most hazardous, stupid xmtrs that most of us have encountered is
the FM-20 and its smaller brothers which have not only the 3 phase circuit,
but a separate 120 volt circuit, waiting to bite you. Any that I have had my
hands in now have the 120V tied to one of the 120V legs of the 3 phase, so
that when it's off, it's ALL OFF !
