For safety reasons, I need to know what are the REALISTIC chances of
120V appearing at the output of a failed basic 12V wall adapter.I would have thought most likely the secondary or primary winding would most likely go open-circuit, or the smoothing electrolytic cap or bridge rectifier go open or short circuit....so I'm hoping that at worst you get 0V at the output.
Can someone tell me the chances of a dangerous situation occuring. What safeguard could I incorporate? Would a GFCI protector do the job? Could I build a discreet GFCI into my circuit? Any ideas?
I intend to produce a commercial project powered with a wall adapter that connects upto the human body.
Thanks
