Owning an RV is not cheap, that's why it's important to maintain your RV with care to keep your maintanance costs down. One of the ways to protect your RV from potential electricity damage (surge) damage is with an RV Surge Protector. With different brands and options available, it was important for me to get the best RV surge protector in today’s market.

In this Article, I’ll Cover 5 of the Best RV Surge Protectors (30 & 50 Amp):

In the end, if money isn’t an issue, deciding between a YETI and an alternative comes strictly down to the features you want.

What’s the big deal?! Why bother??

These may be your exact thoughts!

It seems like such a minor detail among all the other necessary preparations that go along with your RV trip.

With these thoughts, I propose a question:

How important is your RV to you?

If unprotected, one electrical storm can be enough to blow your RV’s entire electrical system and fry out many of your electronics. Even without a storm, in the unfortunate event that you end up plugging your RV cord into a miswired outlet at a park, the extent of potential damage is grave.

You can make repairs and replacements, but those don’t compare to your losing the entire RV along with your precious belongings to a fire.

You can read about a couple’s experience of how a surge protector saved their belongings  here.

A surge protector can be the cushion your RV needs to avoid these annoying and even heartbreaking damages. Obviously if you have a RV Generator powering you RV or Solar Panels you won't have this issue. 

What is a surge protector?

Whether you have a hardwired one installed into your RV’s electrical system or a portable one plugged directly between your RV and the park pedestal, either is designed to give you a sense of security by detecting any faulty wiring in outlets and analyzing any issues with low and high voltage or reversed polarity.

Surge protectors protect your electrical system in measurements called joules. The more joules your surge protector has--the better!

When the inevitable surges occur, the surge protector shuts off power to your RV and analyzes the problem. Most RV surge protectors have light indicators that let you know what the problem is.

If the surge wasn’t too big, the surge protector is supposed to allow power back to your RV after a few minutes.

A surge protector is not to be confused with a circuit breaker.

Although they both shut off your power supply, they have vitally different functions. A surge protector is not resettable but will absorb the surges in order to protect your appliances and electrical system.

Here is further explanation of the difference between a surge protector and a circuit breaker.

In the event of it being an overpowering surge or voltage spike, the surge protector will sacrifice itself in order to save your RV’s electrical system. (Note that this is usually not covered by warranty since it’s designed for this) In this case, you’ll need to replace your surge protector, but it will have saved you potentially thousands of dollars in other repairs.

Your surge protector needs your protection.

Surge protectors are pricey investments we RVers make in order to bring safety on the road with us. Unfortunately, not all happy campers get theirs honestly.

The portable surge protectors are easy to steal. Some come with lock devices for you to lock them down; however, even those may not be enough to keep them entirely safe from theft. Some RV users use cables or build special lockboxes to make their surge protector theft-safe.

It’s recommended to keep the surge protector off the ground and out of water.

Check your surge protector regularly to see if it’s still functioning.

How do you go about choosing a surge protector for your RV?

Finding the right surge protector for your RV is important!

Yes, it does save you from extensive damage, and that’s worth every dollar.

But since it does require a bit of an investment, you want to make sure you get something that covers all your bases and gives you quality service.

FIRST: Determine whether you need a 50 or 30 amp connection. Your RV cord will tell you which one you need.

A 50 amp is 4-pronged while a 30 amp is 3-pronged.

SECOND: Consider the amount of appliances and electronics in your RV. The more you have determines the amount of protection you need.

THIRD: Consider a surge protector with high joule absorption.

FOURTH: A surge protector with a weather shield can prolong its life.

FIFTH: Always consider your budget and look for something that fits into your range but still covers your needs.
