What is an RV Surge Protector?

In the simplest terms, an RV surge protector protects your rig from power surges. Power surges can occur for various reasons from lightning strikes to faulty campground power poles. 

When using a surge protector you will always plug your surge protector into the power pole first. After that, your RV connects directly to the surge protector. That way, if a power surge occurs, your surge protector responds in real-time. It then disconnects from the power source, saving your RV electrical system.

From What Kinds of Electrical Problems can an RV Surge Protector Protect Your RV?

The RV surge protectors you see that cost around $100 typically only protect against increases in power. However, there are many more things that can go wrong with electricity.

That’s where an electrical management system (EMS) comes in.

What is an EMS?

EMS stands for “electrical management system”. It is technically still an RV surge protector, but it has many additional protective features. High voltage is just one issue you can run into with electricity. 

Other problems you might encounter include low voltage, faulty shore power wiring, open grounds, reverse polarity, or damaged power poles. An EMS will protect against all these things.

If you look at the description, you should see the added protections an EMS offers which I’ll cover next.  If nothing else, the price will usually give it away. To get the most protection for your RV, you need to buy an EMS which typically costs at least $200-$300.

From What Kinds of Electrical Problems can an RV Surge Protector EMS Protect Your RV?

You might wonder how big of a deal all those “other electrical problems” are, anyway. After all, if you’re like most RVers you have no doubt heard from someone who has “been camping for decades and never had a problem”. 

Here’s a quick review of the types of electrical problems that an EMS RV surge protector can protect against. 

High voltage/power surges

A variety of faactors can casue high voltage levels. Examples include faulty wiring, overloaded circuits, lightning strikes, or other power surges. For RVers, this can be especially dangerous because electricity running through the system at higher than normal levels can cause short-circuiting and even fires. 

Having too much voltage in your RV’s electrical system can cause serious damage to your RV. You may even have to replace wiring and appliances. It’s important that you take measures to monitor and protect against high voltage.

 

Low voltage 

Low voltage issues are actually surprisingly common in RV parks. The park’s electrical system could falter under the stress of hundreds of air conditioners running. This is a major concern on a hot summer day. 

Low voltage might not seem like a big deal, but it causes increased resistance in your electrical system. This increased resistance means your electrical system is working harder, which can lead to electrical fires.

 

House fires can be traumatic, but RV fires are often even worse. A small space combined with highly flammable materials can quickly ignite. 

Reverse polarity 

Reverse polarity is a potentially dangerous situation. It occurs when a power pedestal or receptacle is wired in the wrong direction. When this happens, the neutral and hot terminals on the device become reversed. This reversal can cause your RV appliances to short circuit potentially damaging equipment or even causing a fire. Reverse polarity can also cause electrocution. 

It’s important to ensure that power pedestals and receptacles are wired correctly. However, you have no idea whether the park pedestal is properly wired when you pull up. That’s why taking proper precautions, by using an RV surge protector is key!

Open ground 

Open ground in an RV power pedestal is no joke. If your rig’s power pedestal has an open ground, your equipment could be damaged. You might even be at risk of electrocution. So it’s important to check that all the wiring and connections. They need to be grounded properly before plugging into a campsite hookup. 

The safest and easiest way to do this is to first plug your surge protector into the power pedestal. It will alert you if there is an issue and then you can inform the park staff so they can call an electrician to resolve the issue. 

Open neutral 

Open neutral is a dangerous electrical hazard that can occur in some wiring setups. It means your devices may not have power but you could still get a nasty shock from it. That’s because anything plugged in is still energized. You won’t know when you arrive at a campsite if the park properly wired or tested the power pedestal. An EMS RV surge protector is really the only thing standing between you and a potential zap.

Is a RV Surge Protector Worth it?

Using an EMS RV surge protector is a relatively affordable way to have peace of mind. Plus it could potentially save yourself thousands of dollars in damage. I have heard from more than one RVer that they fried their electrical system because of faulty power. Guess what they didn’t have? Yep. A surge protector. 

Over the course of our travels, Joel and I have had a few instances where we needed to alert the park staff to a power pedestal issue. We always inspect the pedestal for any visible signs of damage. However, sometimes the only way to know if there is an issue is by plugging our EMS in.

So really rather than asking “is a RV surge protector worth it?” you should be asking if your RV and your life are worth a few hundred bucks. I sure hope the answer is yes. Do yourself a favor because an RV surge protector is worth it! 

For the rest of this article, whenever I refer to an EMS, I’m just going to call it a surge protector. That’s what most people think of them as, anyway

How do I choose a Surge Protector for my RV?

Before I jump into specific models, it is important to know if your RV uses 30 or 50-amp power. If you have a 50 amp RV, you’ll need to purchase an RV surge protector for 50 amps. If your rig uses 30 amp power, you’ll need an RV surge protector for 30 amps

If you aren’t sure if you have a 50-amp RV or a 30-amp RV, I recommend watching the video below. It is a little dated, but it provides an easy-to-understand guide anyone can benefit from.

The Power Watchdog 50 Amp RV surge protector has a lot of features people really love. In my opinion, the biggest selling point compared to other options is the replaceable surge modules.

The company will even send you one free module within the first 2 years of purchase. 

The Power Watchdog has an auto-shutoff feature, but even more convenient is the auto-on. With the Power Watchdog, once the power stabilizes for 90 seconds, the surge protector automatically restores power to your rig.

Another popular and solid brand for a portable 50 amp RV surge protector is Progressive Industries.

The Camco surge protector provides 4,200 joules of protection with the 50 amp RV surge protector. This is slightly less than the Hughes Autoformers Watchdog but more than Progressive Industries.  

It is easy to use, and we are satisfied with our purchase. All you need to do is plug it in and wait for the green lights to appear. Then plug in your RV. Despite consistent use, since 2019 we have had no problems with it. We had one instance recently where the power at the RV park had issues. Our RV power disconnected and there was no damage whatsoever to our rig. Thanks for saving us, Camco.

Frequently Asked Questions About RV Surge Protectors (50 and 30 Amp)

With more and more people taking to the open road in their recreational vehicles, it’s no wonder that people have a growing number of questions. In this FAQ, we’ll take a look at some of the most frequently asked questions about RV surge protectors. Let’s jump in. 

Do I need a surge protector for my RV when plugged in at home?

The short answer. Yes. Using an RV surge protector is a smart move for any RV owner. It protects your RV from power surges caused by lightning or other external sources. It also protects your RV from any electrical issues that may exist in your home power. 

Even if you’re not plugged into shore power, but instead using a portable generator, it is still important to use an RV surge protector for the same reasons. This will help prevent any damage to electronic components or appliances in your RV due to power issues. 

Investing in an RV surge protector is a great way to ensure your RV is always safe from electrical issues that you can find in any home or portable generator system.

Even when plugging in at home, you should use an RV surge protector to keep your rig safe.

How do I Use an RV Surge Protector 30 Amp?

Using an RV surge protector 30 amp model is a great way to protect your rig from power spikes. It’s easy to set up, too—all you have to do is plug it into the 30-amp outlet on the power pedestal at most RV parks. Before you connect your RV, wait for the all-clear reading from the indicator lights or display. They will let you know if there’s an issue with the power source before you plug in.

After the all-clear, you can plug your power cord directly into the surge protector. Once connected, it will protect your RV against any potential surges or other electrical issues that could damage your appliances or electronics. 

How do I Use an RV Surge Protector 50 Amp?

If you are staying at an RV park with 50 amp hookups using an RV surge protector 50 amp is just as easy as using a 30 amp. Simply plug your surge protector into the power pedestal. Then wait for the indicator lights to inform you that everything is clear. 

If you have a 50 amp RV but the park only has 30 amp hookups available, you’ll need to use a dog bone adaptor to “step down” from 50 amps to 30 amps. You’ll connect your 30-to-50-amp adaptor to the power pole directly then plug the surge protector into the adaptor.

You can even add another dog bone to step down from 30 amps to 15 amps. This process will let you get electricity from a regular house outlet. It is very useful for moochdocking. (Aka mooching off your friends and family by living in their driveway now and then). We may or may not be doing this as I write. 

When purchasing a dog bone adaptor, ensure you get the right male and female ends to match your system. 

RV surge protectors can connect to a dog bone like this
This is an example of a dogbone adaptor that can be used to step down so you can still use your RV surge protector 50 amp model when only 30 amp hookups are available.

How to Protect Your RV Surge Protector Against Theft 

While it doesn’t happen often, people have walked off with RV surge protectors. After all, it’s a pricy piece of equipment. The best practice is to lock your unit up using a cable or a bike lock like this one. It’s a super cheap way to stop a few hundred dollars from disappearing. 


Sometimes if the park doesn’t have an easy way to lock our surge protector we just lock it around the pedestal and then also to our extension cord. It is enough to deter theives at least a little bit. A lot of times, that’s all you need. If a real theif wants to get it, there is no stopping them unless you get a hardwired unit. Now please, no one try to steal my surge protector. I would be really sad about it.

Most models will have a security ring you can run your lock through to stop people from taking it. Typically, RV park crimes are crimes of opportunity. So while a lock doesn’t eliminate the possibility of theft, it makes it less likely.  



Concluding Thoughts on the Best RV Surge Protectors 

After carefully considering the features and levels of protection offered by each RV surge protector, the Power Watchdog is the clear winner. Camco offers a good level of protection at an affordable price, coming in second behind the Power Watchdog. 

Southwire lacks in protection compared to other models although it will still protect from most issues. However, the optional BlueTooth display is a nice feature. Lastly, Progressive Industries offers the least amount of protection for the price. 

In conclusion, the Hughes Autoformers Power Watchdog is the most reliable and best RV surge protector. It offers the best level of protection and features at an affordable price.

You need to know that your RV is protected from power surges and other electrical problems. That’s why you should make it a priority to invest in one of the best RV surge protectors. With the right device, you can protect your RV from surges and other electrical issues. That way you won’t have costly damage to your home on wheels.
