Every RVer should invest in some type of digital line monitor that plugs directly into an outlet in your RV. There are several types available and they are inexpensive compared to the repair costs for damaged electrical equipment and appliances. I recommend one that can test campground polarity, measure AC line voltage and if you have a generator measure AC frequency. You should always test the campground wiring for improperly wired circuits before you plug your RV in. Once this is done plug the voltmeter into any 120-volt outlet in the RV where it will be easy to monitor the AC voltage during your camping trip. By monitoring the AC voltage throughout your trip you can protect thousands of dollars worth of electrical equipment and appliances in your RV. If AC voltage drops below 105-volts or goes above 130-volts you should turn electronic equipment and appliances off until the correct power is restored.
