Sorry, Dave, I forgot to mention another aspect of the shock hazard. You stated: > The purpose here is for greater shock protection in case of > polarity reversal. If you think you are safe, you might be in for a bad surprise. It doesn't matter which way you plug your circuit in. With a bridge rectifier, both rods have the same shock hazard. Here is an animation of a bridge rectifier that I posted earlier that shows the voltage across the rods and to ground. (The green arrows show conventional current flow, which is from positive to negative. This is the opposite direction from the flow of electrons.) http://engineering.dartmouth.edu/other/3Dcircuits/animations/bridgeR.html Study this graphic carefully. If you don't understand it, please let me know and I'll try to help. In any event, I'd abandon the circuit you are now using.
