I have two AC mains power leads, A and B, coming from the same circuit breaker having the same neutral. Theoretically one, but only one, of the leads will be energized at any given time, although practically there might be a brief moment during switching (a few milliseconds) when both leads have power (and I can’t have one lead feed power to the other), or there may be a brief moment when neither lead has power and I need the AC to continuously provide power to a transformer/rectifier circuit which powers a 5VDC microcontroller circuit board so the microcontroller won’t reset.
What can I do on the AC side to (a) prevent lead A from ever feeding power to lead B and (b) insure continuous power? I guess (b) could have a solution on the AC or DV side.
Thanks.
