All of the flapping in this thread came from this phrase in post #1: "a capacitive un-isolated standard circuit..." There is no such thing. Six different people have responded, and we envisioned six different circuits based on you description, and all of us *guessed* wrong. Mine had 3 parts, while the schematic you later posted has 14. That kind of disconnect guarantees failure.
You said you provide schematics whenever necessary. This is a question-answer help forum, and your question involves unintended circuit interactions. How is that not the definition of "necessary"?
I brought up your 9-year membership not as some kind of shot at immaturity; just the opposite. I was saying you have more than enough exposure and experience to know what is needed to bring someone up to speed on your situation.
All (other people's) sarcasm aside, there is a legitimate question there. Since you know that the two sides of an AC power line connection are drastically different, why is it possible for the circuit to be connected incorrectly. Polarized AC plugs have been around for over 1/2 century, so the idea that something has a connection requirement that is critical to its operation hardly is new. Is making the circuit universal a real requirement, or can the problem be solved with a less ambiguous power connection?
