Rob - drawings as requested.
The 'problem' with your transformer is that it is designed to cater for multiple needs - and that is what is confusing you.
I've shown 3 possible arrangements:
[attachment=3781][attachment=3782][attachment=3783]
However, reading this Thread again, it seems that your prime requirement is for a 110-v / 120-v. source for your American equipment. So on that basis, I would recommend that you configure the secondary windings for that output only. If you subsequently need an independent and isolated 230-v/ 240-v source as well, I'd look for another transformer for that need. Trying to get this transformer to do 'double-duty' (110-v and 240-v) involves too many compromises.
