Rogue MegaWatt 30Amp bulk charger.
Been using my Megawatt 30 amp PSU now for over a year with the fine adjust pot, when mxwanderer suggested a 500 ohm 2 watt 10 screw potientiometer to replace the rather touchy one screw micro pot. ...

Using the OE pot at max 1K as a pull down resistor, this means LEAVING the oe pot in place, an open circuit to the remote pot becomes a moot point. The control circuit will default to the original pot setting. I am more concerned with inductance than I am with ESD which should NOT be a concern if the circuit is fully shielded, grounded and sealed.
Don't know how much experience you have with lightning but I have seen s frightening amount of voltage induced into isolated circuits. Long lengths of wire, coils, transformers, you name it. The E level is not harmful to humans indeed I doubt whether it could be felt at all, but to an ultra-sensitive circuit the risk isn't worth ignoring.
UN-flat on a 20mv scale is rather loose terminology. However now I am musing the validity of screening the two Megas using a basic Faraday shield. Nicaragua is a hell of a bad place to discover circuit design weaknesses or vulnerabilities.
Sorry Niner, I was using euphemisms to describe tolerating or weighing an unknown risk versus an unknown hazard. For a general idea of one electronic phenomenon, Google ELECTRONIC TANK CIRCUIT, read and understand what it means.
One little, two little, three little millivolts. Four little, five little, six little millivolts...
There's not a lot of lightning storms in Los Angeles, proper. In the desert, further east, during monsoon season, yes. My experience with lightning is that once, while fly fishing with a 9 foot graphite fly rod while on Hot Creek near Mammoth Lakes, as a warm moist gulf of Mexico front pushed in from Nevada to the east, into a cold front coming out of Alaska, I saw it start pouring rain, the baetis emerger hatch went wild and the bite went wide open sub surface. Withing about 6 or 7 minutes, in the rain, with soaked pull over in the summer, I felt the hair on my hands, arms, back of my neck, everywhere, start standing up, while casting.
I immediately set my fly rod down, and crawled under some rocks in the Gorge there, a distance away. I did not want to be the tallest object with the least amount of resistance to complete the circuit.
