ABSOLUTELY CORRECT.
It is NOT a transformer. = NO isolation.
Well it is a transformer, it's just one that has one side of the
secondary tied directly to one side of the primary, hence no isolation.
You can get cheap 1:1 isolation transformers, they're sold for use with
older video arcade monitors. Any place that sells amusement supplies
should have them. I get most of my parts here

Not sure offhand what current the
transformers are good for, but usually a few amps.
