I haven't, but saw one.  It was at the 1 Meredian Plaza fire in
Philadelphia.  They had separate feeds from the power company, apparently
from two substations.  There was a diesel generator driven fire pump as.
 All three failed early in the fire.  The generator ran, but did not
generate.

I have no knowledge as to how the transfer switching might have been
arranged.
