i haven't had a NEC code book in many years
is that 'residential' or commercial/industrial ratings
Pretty sure that applies to commercial/industrial wiring. I don't believe there is any such language in the NEC related to residential wiring. Normally with residential wiring AC compressors will cycle on and off. Electric water heater and fridge, same thing. Is it possible for both AC compressors to run continuously for 3 hours, yes but that is not typical in residential setting. Commercial/industrial wiring code is different. Interior lighting may remain on 24 hours a day. Air handlers of other equipment is also expected to run for extended periods. Hence the difference in the code between commercial/residential and residential.
Monitoring the voltage is a different subject. NEC assumes the supply can handle the load without a voltage drop. We all know that may not be the case in many campgrounds so monitoring the voltage is a good idea.
