The big hazzard using a ct trnsformer in FWB is that the ct may not be
designed to be above ground potential.
Sometimes UTC printed a spec on breakdown voltage on the case or in the
catalog.
Of course you realize this good advice comes to you from someone who started
out in HR using two tv power transformers (not identical btw) in series to a
FWB
Just be careful!
