If you have been RV'ing for any length of time you know that campground power is an ever increasing issue. So what is a surge protector and why do you need one you might ask. An RV Surge Protector is a device that goes between the campground power post and your RV. It can be as simple as just protecting you from power spikes, to as sophisticated as managing the power that comes into your RV, blocking anything that not normal. Many times you will not even know there is a power issue and possible damage occurring to your RV's electronics and electrical system unless you have a monitor or RV surge protector in place. Still confused? Let's look at the problems first and then how you can protective yourself and your RV.
rv surge protector. If you have advance notice, the best tip is to unplug your RV's power cord from the campground power post which will offer total protection from a lightning strike.
The more common cause of a power surge comes from the operation of RV air conditioners as well as the operation of high-power electrical devices (For example a manufacturing plant that has many motor driven machines), close to the campground. These high power consuming pieces of

Other sources of power surges include faulty wiring, problems with the utility company's equipment, and downed power lines. While we where camping in the central portion of Ohio, we experienced a pretty intense thunderstorm, and towards the end of it our power went out. We had been using a RV surge protector and I noticed the RV next to us still seemed to have power. When I checked our connection, we still had power at the campground post, but our surge protector and shut it off to the RV. The display on the surge protector was showing 135 volts (the unit shuts the power off to the RV at 132 volts) which most likely was due to power being knocked out near our location and the campground getting that extra power. Voltage that high is will wreak havoc on sensitiveness electronics such as LED TV's.
Low Power - This may have happened to you, your setup enjoying a nice weekend away with your RV's AC keeping things cool. The next thing you know the sky is getting dark and the power starts to flicker. It's not a storm it's the 45' RV that just pulled in next to you and they just cranked up their 3 air conditioners now causing power issues. If you where monitoring the power as those AC units kicked on your voltage could drop below a 100 volts or lower. This is when things like microwaves, dvd players, AC units and TV's are harmed the most. If you have not monitored this in the past you would be suprised how often this actually happens. Many times it's in a campground loop when everyone is running their RV Air Conditioners. This sag in power could continue for a long period of time and is a major cause of RV electronic and electrical component failure. So you may not see an immediate effect, but many times this is the cause of an AC unit failing sooner than it should.
Some of the other hazards just waiting to attack your RV's electrical & electronic systems are mis-wired campground pedestals, reverse polarity, missing grounds, dangerous current and open neutrals to name a few.
