RV Surge Protector Buying Guide

If you’re still not satisfied with our top pick, then don’t worry. There are tons of other brands which paralleled Progressive Industries. Although we didn’t see any which stood out enough to review them. We have listed a few helpful tips to let you choose your very own top product. See for yourself:

best rv surge protector reviews


Just like tires and mattresses, even surge protectors have voltage, amperage, and wattage ratings. These ratings basically define the limit and extent of the surge protector. Checking the limit against your desired ratings is crucial.

For example, you might accidentally buy a 240 V protector for your 120 V system. Be careful when assessing each and every system. Sometimes the actual wattage and amperage may not be the one displayed or told by your previous owners.

  • Amperage

Amperage is the amount of current that the surge protector can handle. Typically, this number lies between 30 and 70 Amps, although some may even go higher. Ideally, buy one which is within the medial range.

  • Voltage

This defines the amount of voltage the protector was made for. Most household electoral circuits and even those in RVs and trailers use 120V. So only remember to buy the correct surge protector based on the voltage of your electrical system.

  • Wattage

Wattage is the power that the surge produces or absorbs. It’s a bit of a lesser concern but still needs to be accounted for.

Temperature Range

Surge protectors are electronic equipment’s themselves, and as such, are susceptible to changes in the temperature. A good handy protector can handle a wide range of temperatures. Most electronics tend to malfunction or jam in the cold, while others get too warm and cause health hazards.

A good range for surge protectors would be between -50 degrees Celsius and 120 degrees Celsius. Whatever range you decide to choose, it is important that the range extends into the negative side. Operating equipment in the cold is hard, so you want your protector to be extra resilient.

The temperature can also be decided in terms of where you need it. If you plan on taking your RV out in the snow, the protector’s range should be focused more on the negative side. If you want to work in the desert or savannah, then the range should be above 70 or 100.


The durability of the product determines how long it is sure to last. Surge protectors can be very expensive (refer to the Price Range and Discounts section below), and as such you don’t want to spend thousands on new surge protectors every few months. If you really want a good protector, then be sure to buy from approved or certified brands.

Most protectors may only last 14 to 20 months, so you’ll have no luck with them. Be sure to get a decent warranty policy. By doing this you won’t have to pay extra if the equipment gives up.

RV Surge Protector Buying Guide

Efficient Protection

Of course, to choose a good surge protector you need to take into the account the amount of protection it provides. Many protectors fail when the voltage reaches critical numbers (a rare but deadly occurrence).

In cases like these, an auto-shut off function would be helpful. Reverse polarity and open ground protection is also a great thing to have in a surge protector.

Most of the modern ones even feature LED indicators. It indicates when the protector is wired erroneously or when the equipment malfunctions. It is also smart to get an over amperage, wattage, or energy dissipation protection, as those things can majorly alter the safety of the house or RV. But most importantly, remember to check the certifications and approvals (more on this later).

Wiring and Remote Display (optional)

Some newer surge protectors are actually very efficient and user-friendly. An example would be those that use the remote display to show the power source info. These usually have a 15 or 14-inch long wire connected to a separately operating remote LED display screen which shows the amount of current passing through, logs the surges and their time, and does many more functions. Some models can even be operated by a remote control, which is tremendous.

Certifications and Approvals

Like all electronic equipment, even surge protectors need to be certified by approved bodies. The most common certification is UL. Any protectors certified and approved by UL is definitely worth the shot.

Apart from that, The A11 certificate provided by America is the highest that any product can get. CSA is another independent organization which regulates and approves surge protectors. It is very crucial to buy only the best and most authentic protectors.


Warranty is very important and should always be prioritized. Most companies provide only 15 or 20 years of warranty, and some even 5. The Progressive Industries surge protector is protected by a lifetime of warranty.

Products that come with a lifetime of warranty are our favorite. However, these can be pretty expensive, and most only last a year or two. If you want extra assurance, then go for the lifetime option. Otherwise, 20 or 15 years is enough. Nevertheless, make sure that the warranty covers all type of damage.

How to Use/Install Surge Protectors

So now that you’ve bought the surge protector, another question arises in your mind: how do I install this protector? We had the same question, so we called in experts to give us tips on how to perfect the installation.

top rated rv surge protector

Usually, your product will come with a guide or manual to help you install the protector with ease. Many new products don’t even require much effort. However, just in case you are completely oblivious to the installation, here’s how to install a surge protector:

Step 1: Turn Off the Electricity

The first and foremost step is to turn off the electricity to the entire house. It is wiser to turn off the main electrical switch than to disconnect each room as you go. You can find the main switch near the basement, or ask the previous owners where it’s installed. Turn off the switch then install the surge protector.

Step 2: Open the Main Circuit Panel

Once the power is out, open the main circuit panel. This will be in the shape of a vertical or horizontal box. Take the panel out using screwdrivers and get ready to connect the surge protector into the panel. This step is very important and should be done very carefully, as other wires may easily get disturbed or disconnected.

Step 3: Connect the Wires of the Surge Protector to the Circuit

The surge protector has some wires jutting out of it. Have a professional or an electrician connect the wires very carefully. Many people get this step wrong when they do it themselves. Therefore, it’s very essential to call an expert electrician over.

If you can’t afford one or can’t find one, then connect the wires yourself, but be very careful. The wires can be connected wrongly, resulting in miswiring and reverse polarity. Now, this can be a big headache in the long run.

Step 4: Plug the Power Strip

Most surge protectors come with an outlet in which you can connect all of your electronics directly. This is known as a power strip. Many times it is sold separately, while others can be bought along with the protector.

Connect the power strip to the surge protector and make sure that all the wires are tightly pressed. This will help you to connect your electronics directly to the strip and lessen the risk of surges.

Step 5: Plug Electronics into the Power Strip

Now all you need to do is plug in all your electronics for individual rooms into the power strip. Plug in your TV, AC, heaters, coolers, refrigerator, microwave, lights, fans, ventilators, and more. Your RV will be protected from any fluctuations or sudden surges in the current, and you’ll have a power surge-free life in no time. Just be sure to check up on the protector every three months, and take care of maintenance and over usage.


Surge protection has changed the travel world overnight. While many people may not realize it, they are being saved from massive power cutouts, electrical bills, and loss of electronic equipment by just one single tiny device installed inside their RV. So if you’re feeling extra lucky today, then go ahead and try out our top pick, the Progressive Industries Surge Protector. If you don’t like it, then take a look at our buying guide to learn how to choose your brand.

Don’t forget to install your devices properly and as always, stay safe and healthy!

  1. When we bought our RV we were told to get a surge protector so we decided to buy Surge Guard 44280. This was so easy to use and gave us peace of mind knowing our RV was protected when plugging in. You never know when the campsite you are using is going to have the correct voltage.

  2. EMS-PT30X works as advertised. Confirms the electrical circuit is working properly before allowing flow to your RV. It displays amps being consumed so you know if limits are being surpassed. We use a couple of padlocks and a chain with one lock around the cord and the other end locked to the electrical outlet. The delay of electric flow after plugging in or an electrical interruption ensures RV components are protected. Have only used it for a couple of months and so far so good

  3. Surge Guard is still functioning at 100% after more than one year of continual use, in the desert heat. First one I had blew the fuse(not replaceable).Never found the electrical problem,but it never affected my RV. Did it’s worked.
