Please explain what happens if the power transformer’s secondary winding voltage is lower feeding the rectifier, due to a quick AC mains VD event, and the electrolytic capacitors voltage is higher. Just going from memory the rectifier will not conduct and the caps do not get recharged for that "(millisecond pulse)" in time.

Response:
@jea48 You are right - there will be no current thru rectifiers until capacitor voltage will drop below rectifier supplied peak voltage. Theoretically it is possible to build LPS where capacitors keep average instead of peak voltage, but it requires huge inductor in series (in order of Henries) made with thick wire and AFAIK nobody is doing it. One problem is lower rail voltage (average instead of peak) while the other is dependency on the load current.

I prefer Aluminum armored solid conductor 10 - 2 with ground MC (Metal Clad) cable for branch circuit wiring. MC NOT AC metal clad cable.
