Many RVers use a basic surge protector when they hook up their RV to shore power. The more advanced surge protectors are sometimes called an EMS, which means Electrical Management System. Some of these “Smart” EMS surge protectors are built right into an RV, while others like those shown below plug into a power pedestal, and then the RV’s electrical cord is plugged into them. They come in both 30 amp and 50 amp models.
Among other things, a smart surge protector will automatically shut off power to your RV when AC power falls dangerously low or rises dangerously high. It will not allow power to flow to the RV when there is reverse polarity, open neutral, open ground, or when 240 volts is detected on a 120-volt outlet.
