What Is a Surge Protector?

One of the best investments you could do for your RV is a surge protector. But what is a surge protector?

It’s an electrical device that is used to protect electronic equipment against power surges and voltage spikes. A power surge can last less than a second but that is enough to cause overwhelming damage to your appliances. It can degrade their wiring or completely destroy them. That’s why it’s important to use a good RV surge protector.

These devices work by blocking or shorting the current in order to keep the voltage below a safe threshold. They continuously monitor the power supply for any potentially destructive electrical issues, ready to block or short the current.

However, some of the more advanced RV surge protectors do even more. They protect not only against high voltage but low voltage as well. Other types of protection include miswiring at the pedestal, open ground, or open neutral. If a surge protector detects one of these instances, it will notify the RV owner of the potentially dangerous power supply entering the RV.

Surge protectors can be installed inside a home or used outside at the power panel, which is usually the case for the RVs. The first option requires hardwiring, while the second one you simply plug into the power pedestal and it acts as an intermediary between the park’s power supply and your RV.

Do You Need a Surge Protector For Your RV?

In our opinion, all RVers can benefit from getting a surge protector. It can really save you a lot of money that you might otherwise have to spend on repairs of your RV equipment. All it takes is one voltage spike to cause damage to the RV’s electrical system. So investing in a surge guard makes total financial sense, especially since power fluctuations are fairly common at campgrounds. Buying one of them is a lot cheaper than blowing out the RV power system.

How to Choose the Best RV Surge Protector? – RV Surge Protector Buying Guide

There are many different surge protectors on the market. And to understand what is the best surge protector for an RV, it’s important to know what features to look for. So in this surge protector buying guide, you can learn about the most important things to bear in mind before making a buying decision.

Amp Rating

The first thing that you need to take into account before choosing a certain surge protector for your RV, is to determine its compatibility with your RV’s amount of electricity. For this, check the amperage rating of the device. Most surge protectors offer either 30 Amps or 50 Amps. To differentiate between the two, the 30 Amp plugs have 3 prongs and the 50 Amp counterpart has 4 prongs.

Choosing the right amperage rating is important to ensuring that the new device will be able to meet your RV’s electrical requirements. If a surge protector isn’t matching your RV’s power supply, it can lead to the device failing to perform its function. Moreover, it can lead to overheating and other electrical issues.

Joules Rating

Another crucial factor to take into account is the device’s Joules rating. It shows the level of surge suppression that the device can provide. And the higher the rating, the more heat it can absorb and dissipate in the event of a spike.

LED Display

Most surge protectors are designed with an LED display that typically shows the voltage and amperage, as well as any error codes. Having an easy-to-read display is important to the proper use of the surge protector. So look for a display that is bright and which has easy-to-understand indicators.

Level of Protection

  • Surge spikes. This is the main purpose of surge protectors, which protect the equipment of your RV against sudden spikes in voltage.
  • Reverse polarity. You can’t always expect electric work at campsites to be done right, which often happens when the work is done not by a professional. One of the common problems is finding that an outlets’ neutral and live wires are connected to the wrong terminals. And if you connect your RV’s power supply to such a faulty power pedestal, it can result in damage to your equipment. That’s why some surge protectors offer reverse polarity protection, so you can protect your rig before it incurs any damage.
  • Open ground. Surge protectors rely on plugging into grounded outlets. When a large surge hits, the ground wire disperses the excess voltage, taking it away from the protected equipment. However, if the grounding wire is not properly connected or damaged, your surge protector won’t be able to properly function. Fortunately, some of the EMS devices notify you of this issue before it costs you time and money.
  • Accidental 240V connection. If you’re traveling in your RV around the United States, you’re using 120V. However, if you by accident plug your rig into 240V, it can cause damage to your electronics. For this purpose, some of the surge protectors notify you if the power pedestal has a 240V outlet.
  • A/C frequency. This is another protection feature that is common for EMS units. It works by monitoring the alternating current frequency and protecting your devices if the frequency deviates too far from the standard level.
  • Thermal protection. Some of the devices also come with a thermal sensor, which will shut off the power supply to your RV in case if the power pedestal outlet will start overheating.


Depending on the type of surge protector, in the event of a power surge or other electrical issue, it can either just bring the voltage to a safe level or completely shut off the power supply to your rig. In the case of the latter, once the power conditions are back to normal, the device can either automatically reset on its own or require manual resetting.

Ease of Installation

When considering RV surge protector pros and cons, it’s also important to take into account the ease of installation. For the easiest option, choose the plug-and-play design that requires no installation whatsoever.


If you’re choosing a portable RV surge protector, consider getting a lighter unit. Since you’ll have to take it out every time you stop at a campsite, you want a device that is easy to carry around.

UL Certification

To choose a high quality product, look for one with UL certification. It will give you peace of mind that you’re buying a safety tested product. If a surge protector has a UL seal, it usually means that it’s a more trustworthy and more reliable product.


Everyone has their own budget and before buying a particular surge protector, it’s important to determine it. You don’t want to overspend but also you don’t want to skimp on the device that will guarantee your safety.

Hardwired vs Portable

There are two types of RV surge protectors: hardwired and portable. Most of the options available on the market are portable. However, you can also find devices that are hardwired.

  1. Portable surge protectors are usually more common due to a few advantages. First of all, they eliminate the need for an installation. Typically, you just plug one of these units into the power pedestal and they are ready to be used. There isn’t any complicated wiring work to do and if there are any issues, you can easily replace them without any hassle. Secondly, portable units are usually very compact, so when you’re not at a campsite, you can store them away in the glove compartment or any other small space.
  2. Hardwired surge protectors, on the other hand, are installed in the interior of the RV. This might require the help of a professional, unless you’re fairly DIY savvy. The main benefit of this type of surge protector is that once you’ve installed it, you can forget about it. You won’t need to take it out and connect it to the power pedestal every time you arrive at a campsite. Another advantage is that since the device is kept inside the RV, there’s less chance of potential theft.

Electrical Management System vs Surge Protector

You might have noticed that in our surge protector reviews we’ve been using these two terms almost interchangeably. However, there’s a difference between the two, so let us clear up that confusion.

  1. The main purpose of a standard surge protector is to protect your equipment against a severe over-voltage spike. So these devices are more simple and as a result, they are more affordable. Since voltage spikes are the most common issue, a lot of people consider having a simple surge protector to be sufficient.
  2. EMS devices are designed to be more sophisticated in their technologies, resulting in a higher level of protection. Except for the high voltages, EMS units can also provide protection against low voltages, open grounds, open neutrals, reverse polarity, and overheating. All these issues can also occur at the power pedestal. And an EMS device can detect and protect against such problems.

Most people who opt for a standard surge protector, do so because of the lower price. However, if you want complete protection for your rig, it’s better to invest a bit more and get an EMS.

RV Surge Protector Manufacturers

Progressive Industries make the best surge protectors. The company was started in 1999 by an RV owner who saw the need in the market for RVs’ electrical protection with more sophisticated systems. Today, they have a wide range of surge protectors, so it’s easy to find one that will meet your particular needs. Their products are designed in the United States but are manufactured in Mexico. They are known to provide reliable products, which also come with a limited lifetime warranty.

Southwire is another brand that offers good surge protectors for RVs. However, unlike Progressive Industries, they don’t specialize specifically in RV equipment. They make plenty of other electrical products. The downside to that is the smaller selection and slightly lower level of innovation. Moreover, while Progressive Industries products act as both surge protectors and electrical management systems, most of the Southwire line is just standard surge protectors. As for the warranty, similar to Progressive Industries, Southwire also offers a limited lifetime warranty.
