Progressive Industries electrical management system (EMS-PT30X). This EMS checks for low voltage (can damage AC and microwave) and reverse polarity (can allow electrical shocks) as well as over voltage and other electrical problems at the campground source. It cuts off during low voltage (below 108 volts) and notifies at hookup if reversed polarity. Low voltage at campgrounds occurred more commonly at rural campgrounds. Reverse polarity was present at a public campground.
