Would not an isolating transformer still be a risk?

The isolation transformer will eliminate the ground problem, but the issue of wire to wire with 120 volts or so still exists. :) Jinx wrote: > > >> Just isolating with an 1:1 transformer will not be the same ? >> > > I have an isolating transformer that could be thrown into the mix > > -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
