Why Do You Need Surge Protection?

Whether you’re driving an RV, fifth wheel, or any other type of camper, you most likely will use a campground power pedestal to get a little juice for your trip.

The chief problem with this is that campgrounds can experience power spikes and fluctuations from time to time as a result of thunderstorms, faulty power connections, or as a result of being overtaxed.

When this happens, the irregularities of power can destroy your electrical devices immediately or over time.

Electrical systems are expensive to repair and the quality of power that is provided at campgrounds is completely out of your control, but one way that you can protect your property is to buy a dedicated surge protector that will regulate the flow of power to your devices.

What to Look For Best RV Surge Protector


Also known as the size or current of the surge protector, amperage is one of the most important attributes to consider. This is the volume of electrical energy that flows through the appliances that are connected to your RV at any given time.

Always ensure that you get the right size, which means that you’ll need to check the ampoules of your surge protector; this is indicated on the surge protector itself, and it will let you know which kind of power that you will use when you plug it into your RV.

There are two types of amperages for RVs; 50 amp and 30 amp, Better RVing has a great video about each.

  • Generally speaking, larger RVs with two air conditioners and multiple appliances will need a 50 amp or higher surge protector.
  • If you have a lower overall electrical footprint, then a 30 amp model will do.
  • In any situation, always select the surge protector that is best matched to your energy needs, this will decrease the chance of electrical failure or mishap.

RVs have different power needs; check out this guide on Basic RV electricity if you have any questions.

Protection Rating

The most important statistic that you can have in a surge protector is its protection rating.

Simply put, this is measured in joules and will let you know exactly how much energy a surge protector can dissipate safely.

For example, if you’re in a lightning storm and a bolt hits a transformer, the excess electricity will hit your surge protector. If it has a high enough protection (joule) rating, it will dissipate the extra energy as heat, which will protect both you and your connected devices from the excess electricity.

With this in mind, shoot for a higher joule rating so that you can have a maximum level of protection.


As you’ll see in our review section, there are typically two types of surge protectors for RVs; hardwired and portable. The difference between the two is pretty important, so let’s take a look at each in-depth:


These are firmly connected to your RV’s internal components; typically where the power enters into it. This is mostly in the compartment where you find the wiring that draws power from the pedestal itself.

This is a very useful type of surge protector because you never have to think about whether you’re safely protected from power spikes and fluctuations as it is always on when you are connected.​

Additionally, since this is wired directly into your RV, you don’t have to worry about unscrupulous individuals attempting to take your protector.


Portable units are fairly convenient because they require no installation and connect directly into the outlet of the electrical pedestal provided by the campground.

These are designed to warn you if there is any type of potential danger from the connection as the result of a spike or strange fluctuations. These are also designed to be used safely in any type of weather.

The best types of these will provide protection and warn you when there are spikes due to high voltage and also when there are low voltage energy emissions due to faulty wiring.
