Buyers Guide For RV Surge Protectors For 50 Amp

RV surge protectors are not just for ensuring that your vehicle’s electronics and appliances will continue to work even when you get close to the maximum amount of power coming into your RV. They are also a good tool for saving your RV from potential damage if you happen to experience a power surge.

How you connect an RV surge protector to your 50 amp electrical system depends on which type you decide to purchase. This can seem pretty confusing at first, but after reading the following article, you will be able to confidently make a decision.

At first sight, a high-quality, extremely safe RV surge protector could seem a little costly. However, the price of a protective device against electrical surges appears insignificant when you take the expense of repairing your RV’s equipment into account.

An excellent circuit stabilizer for an RV properly controls and safeguards your electrical grid.

It’s never a good idea to switch your RV into an untested source of electricity, such as one found at a campsite, conservation area, or RV park. Also the park management may not be informed of any concerns with any power installation at this time. A strong circuit stabilizer is a necessity given the many sources of electricity that we plug our RVs to.

In order to maintain your RV and its gadgets electrically insulated from shocks and other electrical problems, nowadays we’re looking at the finest RV equipment.

What to Consider When Choosing

Keeping an RV in tip-top shape is no easy task, and we get that. However, if you regularly take your RV on vacations, you should know that the power systems present in the parking spots and campgrounds don’t have a reliable power output, so you should be prepared for power surges. You can avoid the danger and save thousands by installing a good surge protector in your RV.

In this buying guide, we will go over some of the most important things to consider when looking for a 50 amp surge protector for your RV. Let’s get going!

Now let us take a closer look at what you should remember before purchasing an RV surge protector and what features you should seek for in one.

The Reaction Time

Among the many aspects of RV circuit stabilizers to consider, reaction speed is among the highest.

Which is to say, how soon the circuit stabilizer in the rv will react to, say, an unexpected increase in voltage. So that the power supply problem doesn’t wreck your RV, you would like this to be as minimal as possible.

A reaction speed of 1 ns or less is recommended for RV surge protectors (one billionth of a second).

As a result, your RV will be safe from damage since the unit will have already unplugged from the defective power supply.

Rating of the Unit

The amount of protection offered by a surge protector is clearly labeled. This quality, expressed in Joules, should be prominently shown anywhere on the packaging or description of the item. If you want to know how much energy a surge protector can properly handle before this breaks, look at its joule certification.

A strong joule level is essential for any RV circuit stabilizer to ensure the safety of each of your electrical devices while on the road.

In general, circuit stabilizers have a rating between 825 and 3,580 joules.

Quantity of Ports

Every customer must verify the number of ports for each choice. This factor will assist in determining if these individuals need to replace several surge protectors. There are variants with 6, 8, and 12 ports as well as those with 4 ports.

Consequently, you must determine the number of needed ports for your RV. It is not a tough process, however it will rely on the number and kind of devices in your vehicle. If an RV owner has just a few gadgets, he or she will not have to purchase an alternative with more ports.

Develop Quality

After selecting the proper kind, you should evaluate their constructibility. Hard – wired versions are often superior because they’re placed within the RV, making them less susceptible to harm. In the event of connector gadgets, you should verify whether or not the voltage converter is hermetic. The waterproof surge stabilizers may be utilized in rain, storm, etc., as you sleep in your RV while being on holiday. Instead, you would need to constantly monitor the environment and handle it with caution.


Weight should be considered while selecting between several portable EMS devices.

Although it is not the most crucial factor to consider when selecting a surge protector, you should avoid selecting one that is cumbersome to move and establish whenever you change places.

Seek for a mix among small size, simple design, and weather-resistant materials that offer appropriate durability.

There is no need to purchase a hefty circuit stabilizer that brings additional weight to your RV and makes establishing a new location more difficult.

Security Accreditations

Unnoticed are the safety certifications granted to each type by groups dedicated to making sure that these items function properly. In this scenario, you should seek for a solution that has been certified by Underwriter’s Laboratory (UL).

It’s known as the UL mark, and it certifies that your circuit stabilizers will perform without posing any safety risks. It means that the item will not pose a significant risk if anything such as high voltage happens.

Build Quality

Once you’ve determined the best 50 amp surge protector for your setup, you should evaluate its build quality. Because they are permanently mounted inside the RV, they are safer from damage and is, therefore, the better option.

For 50-amp permanent surge protectors, however, it’s important to make sure that the units you’re considering are protected against the elements.

Joules Rating

The level of surge protection your RV surge suppressor provides is largely determined by its joules rating. Surge protectors’ capacity to dissipate heat during sudden increases in electricity supply from a power pedestal is one of their most important features.

Higher joules ratings offer greater safety from more severe power surges. Overheating protection during power surges is also improved. Considerations such as the expected lifespan of the surge protector and the frequency with which power surges occur will determine the appropriate joule rating for your RV.

In most cases, the level of safety provided by a surge protector depends on its joules rating and how often it is subjected to surges and spikes. Make sure to take this into account alongside any other criteria in order to make the most educated choice possible when purchasing a surge protector for your recreational vehicle.

Safety Certifications

Each model comes with a different set of safety certifications from groups whose sole purpose is to make sure these products are safe and reliable. You should look for a solution that has Underwriter’s Laboratory (UL) approval in this case. The UL mark is your assurance that your surge protector has been tested for safety and will perform as expected. It shows that even if the voltage gets too high, the device won’t cause any serious problems.


Surge protectors for 50-amp RVs can be found for under $100, but you should be wary of devices that cost less than $50. According to our findings, the best RV surge protectors can cost as much as $300. Obviously, your financial plan is entirely up to you. When deciding whether or not to invest in a surge protector, it’s important to think about how much it could cost to repair any damage caused by electrical problems.


Finally, before buying anything, make sure you read the warranty details. There are some brands that provide a lifetime warranty, while others only cover the first year or so. If you want the peace of mind that comes with knowing you can simply replace the surge protector if anything goes wrong, it’s best to go with one that has a lengthy warranty.

In the case of RV surge protectors, a number of companies give a lifetime guarantee, whilst others offer a 1- or 2-year guarantee. It is usually preferable to choose a circuit stabilizer with a wider warranty duration so that you may simply obtain a new one if anything goes wrong.

Types of RV Surge Protectors for 50 Amp

There are many different surge protectors for RVs. Some RV owners use a different type of surge protector based on their camping location and the type of camping they do. Let’s review some of the different types of surge protectors and find the best RV surge protector.

First and foremost, you should be aware that there exist 2 types of surge protectors provided for RVs: hard-wired and portable devices.

The hardwired units are located right in the RV, however the construction is more complex, therefore you may want to engage a specialist.

The portable plans, in contrast, link in between the process of connecting, which is rather easy and can be done by anybody.

In addition, they are versatile, and you can quickly transport them or give them to those who need them.

Yet, portable devices are more likely to be stolen since anybody can just disconnect them and take them, while hardwired ones are more secure. Thus, each form of circuit stabilization has its own advantages and disadvantages.


A portable RV surge protector of 50 amps is simple to operate. Simply connect it to your RV’s power cord and plug it into the site’s power outlet. The device’s plug-and-play functionality is also a big selling point. You can take it with you from RV to RV, and it can be taken apart and reassembled whenever you move to a new campground. It will also be simpler to replace and not require any hard wiring into your RV.


Another option is to invest in a permanent surge protector. The 50-amp surge protector is permanently connected to your RV’s electrical system through a hardwired connection. Installing it where you normally keep your RV’s power cord is the most common practice. The convenience of not having to unplug additional devices when you reach a new power hookup is one of the many advantages of this type of RV surge protector. Your surge protector will be hidden from sight, making it less likely that it will be stolen. The storage area of your RV provides excellent protection from the elements, so you need not worry about storing your belongings there.

How We Chose Our Top Picks

Traveling is where we do the bulk of our studying. We looked into the most commonly purchased 50-amp RV surge protectors online and made a list of the pros and cons of each model. Then, after taking into account the opinions of our fellow RVers, we made our final selections.


How does a surge protector for an RV operate?

A circuit stabilizer protects your RV’s interior equipment against over voltages from the shoreline power supply that might be hazardous or damaged. This is quite comparable to utilizing a surge protector in your house; but, the electricity comes via a 30-amp or 50-amp device that is intended to absorb electrical surges before they hit your RV.

Does a surge protector in the electronic circuit box cover my whole residence?

Yes, yet there are other ways that spark could reach a house. After a hit, the most usual route is down the primary power, fiber, or telephone service. Thunderbolt often follows the route of low effort to rapidly deplete its power. Although lightning is tremendously strong, it is also rather slothful; its preferred route is one that is unencumbered. A whole surge protector can safeguard your whole home after the voltage level reaches the panelboard, but it does not avoid electrical harm to networks struck by the thunder before something gets the electrical outlet. This is the reason supplementary “juncture” surge breakers and connectors are crucial for a maximum protection strategy.

What characteristics might a surge protector possess?

Pick a good surge protector with a minimum joule strength between 200 – 400. Sophisticated or expensive gear, including desktops, screens, and sound system, need a minimum joule level of 1000. A joule level greater than 2000 signifies extra safety.

Can a surge protector save energy?

No. An over voltage regulator is only a barrier and not an energy-saving tool. The electricity that reaches your surge protector has already traveled from your meter and been registered on your bill with your electricity network operator. The surge protector is solely intended to resist power spikes.

Are surge protectors essential for RVs?

Even under ideal conditions and with a reliable power supply, the energy infrastructure is vulnerable. There might be outages, fireworks from a storm, or a fault with the transmitter that affects your interior equipment. A surge protector for an RV is meant to switch off in the event of “dirty power,” inadequate voltage, or power surges. In the case of a power disaster, surge protectors give peace of mind and assist in preserving your RV.

Does my RV require a surge protector?

After investing in your RV, utilities, and other equipment, it is prudent to spend between $50 and $150 in their protection. Prior to actually connecting your equipment, the vast majority of surge protectors verify the right wiring at the base, providing you with quick assurance that the power source is acceptable.

How does a surge protector function, and what is it?

Surge protectors are designed to shield your recreational vehicle and any electrical equipment plugged into it from potentially dangerous spikes in electrical current. When there are problems with your RV’s power supply, a surge protector will alert you to them before they damage your RV’s electrical system or its appliances. It will cut the power to your RV if it detects a problem.

What joule rating would be considered adequate?

An adequate surge protector should have a minimum rating of at least 1000 joules. There should be between 1000 and 2000 joules of energy to safeguard the electronics inside a typical recreational vehicle.

Does a surge protector rated for 50 Amps work on 30 Amps?

Yes, a 50-amp protector can be used with a 30A RV. Still, it’s not something we’d suggest you do. Leaving your RV’s electrical system and appliances unattended for extended periods of time increases the risk of failure. Both 50-amp and 30-amp surge protectors are built to cut off power instantly if the voltage goes outside of a safe range.

The thresholds of the various surge protectors are where the main distinction lies. If the threshold of the 50-amp surge protector you’re using is too high, the power won’t be cut off as quickly as your 30-amp RV requires. Your RV’s electrical system may be particularly vulnerable to damage because of the additional stress from frequent power surges.

Should I bring in my 50-amp RV surge protector during inclement weather?

This question defies a simple Yes or No response. The ability of a specified surge protector to withstand the elements is dependent on the manufacturer from which it was produced. That is to say, there isn’t a universal standard for surge protectors’ waterproofing features across models and brands.

Most 50 amp RV surge protectors are built to withstand extreme weather, which is a huge relief. Still, before making a final decision, you should research the model’s waterproofing rating.

Final Thoughts

RVs that use a 50-amp service must have a surge protector rated for that amount of power. Don’t drive around town without it, or you might end up breaking some of your rig’s appliances. A surge protector is inexpensive compared to the cost of repairing your RV after a power surge.

Investing in a quality device isn’t cheap, but the money you save on repairs to your RV’s power system and appliances more than makes up for the initial investment. If you’re worried about power surges damaging your gear, you can rest easy knowing that it won’t matter where you plug it in.
