First: on 50 amps Reverse Polarity should not be possible, OPEN GROUND however is.
Second, There are two different 50 amp surge protectors. On one there are LIGHTS, I do not recommend this one as it is a simply spike suppressor nothing more
The second has an LCD screen, reports voltage, current and error messages, This is the one you want.
I would have to say that anything "Can" happen. When I plugged into a 30 amp reverse polarity plug with my RV, the Trace inverter/charger did not like it - to the tune of $450 in repair costs!
Well, I agree anything CAN happen, I do know of a case or two of reverse polarity on a 50 amp system.. On of those cost Consumer's Power (Jackson, MI) several thousand dollars worth of fried electronics since they reversed it,, but .. As I said, that SHOULD be impossible. (not is, SHOULD BE)
What happens when you reverse polarity on a 50 amp? One leg is 240 volts (That is genuine reverse polarity)
On a 30 amp circuit, it is both very easy and far too common, Simply means you swapped the black and white wires..
IN his case, I do agree it is likely a neutral/ground potential difference he is seeing,, This may or may not indicate a problem.
