RV Surge Protector Buyer’s Guide
So, you’ve read all our RV surge protector reviews, but you’re still confused about which model to go for. Well, don’t worry. With the different aspects and features in this section, you’ll learn what to consider. Take a look:
1. AMP Rating
One of the first things you’ll have to think about is how many AMPs the system can handle. To explain amperage, we can say that this is the amount of electricity that goes through the current. Every electronic on your RV will have a specific amperage need, so it is crucial for the surge protector to match that amount.
Usually, they go from 30 AMPs up to 50 Amps. These limits will tell you how well it will work, depending on the capacity of your trailer electrical system.
A 50 AMPs model can work with less than 30 AMPs without problems. But you can’t hook up a 30 AMPs protector to a system that uses more than 30 AMPs as that could end up in overheating and similar electrical issues.
Most 50 AMPs protectors come with 4 pins, while 30 amp surge protector come with only 3 pins. Each model offers a specific type of compatibility with your system.
2. Joules Rating
Joules is another measurement of electricity. But this one doesn’t refer to the current but to the force. In short, it is the amount of force created by electricity within electrical systems. When joules increase, electronics tend to overheat.
Knowing this, you should always make sure that the surge protector can handle the number of joules a surge can produce. This will prevent your appliances from getting fried.
In this measurement, the count tends to be between 800 and 4000 joules. The more joules the protector can handle, the better it will be for your electrical system. We recommend going over 1000 joules of protection for the safest result.
Voltage refers to the force electricity uses to pass through wires and electrical systems. So, it is essential to know how much your surge can handle. Here, you will find that most systems use either 120v or 240v. But you can also find 140v models in the US and other countries.
Some countries even use both 120v and 240v. As a measure of force, this is critical to get right, as it could eventually have a significant impact on how well your RV handles the electricity.
Luckily, most trailers work well with 120-volt protectors because that’s the usual system they use. But it also depends heavily on the country you are in. In Europe and Asia, even motorhomes use 240v systems, so you’ll have to pick accordingly.
4. Watts Capacity
Watts is the actual measurement of electricity. But most of the time, it is used to know how much energy a product uses.
This watt measurement is also essential to consider in surge protectors because watts is the amount of electricity that every appliance will need. But if the electrical system provides more wattage than required, and the appliance overcharges, you could end up with overheated, burnt, or faulty electronics.
That’s why it is vital to get a surge protector that could handle as many watts as possible to prevent any damage to your appliances. The regular amount of watts a protector supports goes from 1000 watts up to 12,000 watts. We recommend going for the highest amount possible – that will ensure much better protection overall.
5. UL Seal
Not many people know this, but a UL seal is a pretty big thing to think about. It refers to the Underwriter’s Laboratory, a certification system that guarantees the product as an effective one.
This won’t make a protector necessarily better but offers the chance to know that the product you’re getting is backed up by a reliable organization.
6. Protection Level
This refers to the different types of protection you’ll get with the system. The best RV surge protector will protect you from all possible issues.
Here, you’ll find problems like frequent power surges that increase voltage, watts, amps, and joules in systems that could end up burning your appliances. Then, you’ll find the opposite, which is low voltage problems which could cause your systems to become faulty due to lack of power.
Other problems like grounding and miswiring are also common within trailers, so they are essential to consider when getting a new surge protector.
But it is not only the type of protection you’ll get but how fast the protector will react to the problem. Remember, surges, and other electrical issues happen in a blink of an eye, so it is essential that the surge guard works fast enough.
Our recommendation is always going for systems that are super responsive like Progressive Industries and TRC models – two brands that make sure your RV is secure. All the protectors from these brands response in nanoseconds, which prevents damage to your electronics from slow shut-offs.
7. Diagnostic Functions
Apart from protecting against different types of problems, it is also crucial that the surge shield diagnoses when there’s a chance of something happening. You could say that a diagnostic feature will prevent issues before they even happen.
Most models nowadays come with pedestal diagnostics, surge analyses, and other similar voltage or electricity testing functions. This allows the device to prevent most issues.
8. Type of Installation
The installation system is also critical if you want to know whether the device is ideal for you or not. The primary purpose is to decide between hardwired and portable designs.
A portable model comes with a plug-and-play design. That means you won’t have to make any installation apart from just hooking up the protector to an outlet. Then, you can connect any electronic or electrical system to it. This will keep everything that connects to the protector safer.
In contrast, a hardwired system needs to be installed in walls. These are often less convenient for trailers because you’ll have to set up a whole space for their installation and eventually connect the wires directly. But it offers a more permanent solution, and sometimes a much more reliable one.
9. Ease of Installation
While portable designs are often easier to install than hardwired options, they both also differ within their own categories. Some portable models are not as easy to set up as they seem, and hardwired systems can also be easy or too difficult.
That’s why we recommend going for the most straightforward designs as possible. Of course, plug-and-play models are always better for their portability. But if you go for a straightforward hardwired design, you may get something easy to install and probably more protective.
The weight will have a considerable impact on how easy you can transport the protector and how easy it will be to hook it up to the electrical system in your RV. Of course, the lightest models are always more practical.
11. LED Display & Lights
Having LED lights and a display on your surge shield will be a significant advantage to consider. This happens because lights and LEDs tend to display whether the electric system is working as it should or not. Some screens come with specific error codes or issues that will let you know automatically.
On the other hand, the lights and displays will make it easy to know whether the protector is turned on or not. Otherwise, you may end up confused about the performance of your surge guard.
Not many people tend to consider the price of a surge protector because they instantly think they are expensive, no matter what. But you can actually find affordable options that won’t deliver many drawbacks.
These models are often portable and easy to use. They may not last as much as an expensive surge shield, but they will probably stand several months or years of use while protecting your appliances effectively.
We don’t recommend protectors that produce any noise. When this happens, it is usually a sign of a problem inside the device. Sometimes, these sounds can even become dangerous and make it impossible to touch the product.
Overall, we encourage noisy surge protector owners to get rid of their old models and get new ones. That will make them safer.
Different Types of Surge Protectors
You already went through all the important factors, it is time to learn about the two main types of protectors out there:
These go directly into the power lines of buildings. Also known as hardwired protectors, they offer the safest and most protective systems. These can often handle lots of outputs. They are better for entire residential units or large commercial properties.
The only issue is the installation. These systems tend to demand several minutes or even hours to start working.
These are the portable ones that you can connect to almost any system using an outlet. They come with standard connectors so you can connect them directly and then connect appliances or entire small electrical systems to it.
You will only get one output with a secondary type protector. But they offer almost the same kind of protection but with lots of extra portability & convenience. The issue is that if you want to protect more than one appliance, then one of these may not be ideal.
Benefits of Using an RV Surge Protector
A surge protector is not only a means of protection. There are actually a few different things that you can get from it, such as:
- It keeps your appliances free of electrical damage. If something terrible happens, they will be protected from any overload.
- Low-voltage problems tend to produce damage in electronics as well. If the electrical system hesitates or fails, a surge protector also keeps your devices safe.
- You will know whether the power source of your RV is working correctly or not. It will also let you know how many appliances you can use without producing damage.
- Surge protectors are way more affordable than entire electrical systems. You can save several hundred dollars with one of these.
- Surge protectors can detect fires, overheating, and melting issues and prevent any problem from escalating.

As for the place to buy them, we recommend Amazon. This happens because you’ll find the most extensive array of options, with models from all kinds of brands and types that you can pick according to your needs.
Other online retailers may be helpful, as well. But they are not as fast, reliable, or cheap as Amazon.
5. Should I Go for an Electrical Management System (EMS) or a Surge Protector?
An EMS is also a type of surge protector or at least a slight alternative. But they are mostly the same.
For us, you can choose either and still get all your RV electrical system to be protected. However, EMS devices are often more practical with a few more features than standard surge guards – so they can be excellent options.
6. How can I use an EMS with an RV Inverter Generator?
An EMS is the best option if you have an inverter generator on your trailer. They are often used for recreational purposes only, like installing decorative items and other appliances.
But if you have an EMS, then you won’t be able to use the inverter. This happens because they won’t let any electric flow go into the vehicle.
7. 50 AMP or 30 AMP RV Surge Protectors: Which One to Go for?
It all comes down to your specific needs. As you should know by now, most 30-AMP protectors work with 30-AMP RVs – and the same happens with 50-AMP options. But if you intend to update the power system of your trailer in the future, going for a 50-AMP model can be your best choice.
8. What is the Warranty of Surge Protectors?
The more warranty you get with your surge protector, the better. They should have at least 1 year of warranty with full reimbursement or replacement availability. But we recommend models with 3 or 5 years of warranty for the best results.
Most surge guards tend to last a long time, sometimes decades. That’s why some brands may even offer lifetime warranties, which can be a huge plus. You won’t have to worry about your protector or its parts, even in the long term.
9. How to Install an RV Surge Protector?
The installation process of a surge guard shouldn’t take more than just a few seconds or even minutes. Especially if we’re talking about portable models, you will probably only have to connect the device to the outlet, and that’s it.
For hardwire systems, the process could take a little longer. But overall, it is just about screwing the protector to the wall, hooking up the cables, and that’s it. An experienced contractor or electrician can do this in less than 10 minutes.
10. How to Secure an RV Surge Protector?
Securing the surge protector on your RV is all about making sure that it won’t fall off when you’re driving. To make sure of that, you can use the locking brackets most models come with. An alternative can be screws, bolts, or hooks. We recommend using covers on top of the protector for extra safety.
11. How to Use an RV Surge Protector?
You just need to connect the device depending on its design, and then hook it up to your electric system. Most surge shields work automatically, so you won’t have to do anything to operate them. Still, you should read their user manual if possible.
