Important Considerations Before Purchasing RV Surge Protectors

There are many factors you need to consider before finalizing your purchase decision. Why does this matter … because there are so many brands available on the market. Picking the right option can become a bit of an eschewing job and you don’t want to waste your money on a product that doesn’t fulfill your needs.

Here’s the deal! We are listing some important features that you must take into account while considering a surge protector for your recreational vehicle. The list is as follows:

RV EMS vs. Surge Protector

Outdated RV site pedestals are bit of a problem because surge protectors only offer limited protection with these pedestals. If you are facing the same scenario, then opt for an electrical management system or EMS.

EMS is far more expensive than a surge protector but here’s the benefit!

It offers a lot more protection as compared to surge guards. But an EMS is a better option for avid RVers. If you go to a properly equipped and updated campsite, then a surge protector will also do the job for you.

Joules rating

Joules rating is critical and you must consider before buying a surge protector for your camper. This rating is the level of protection or voltage surge suppression that the unit can provide to your recreational vehicle.

It will also measure the ability of the unit to disperse heat caused by the surge spikes. In simple words, if this rating is higher, the unit will offer better protection and will last longer.

Amp rating

Another rating that’s crucial is the amperage rating. A unit will only be able to perform its function if it doesn’t get an adequate amount of electricity. If it doesn’t get the amount of electricity according to its amperage rating then it won’t function properly and your rig will not be safeguarded from voltage fluctuations or surges.

UL listed

Always look for a UL listed piece of equipment when you are buying a product that has something to do with electricity. Here is why … UL certification guarantees that consumers are buying quality assured and safe products. It means that this product will be safe for them to use for their camper. Furthermore, this certification guarantees that the product offers a good bit of longevity too.

Additional features of the unit

There are some surge protectors that come with additional features. You can prioritize each of them based on the campsites you visit and the weather conditions. For example, some surge protectors come with waterproof capabilities.

Some of them also come with features to automatically cut the power in case of power surges and turn the supply back on when things get back to normal.

Also, there are different types of surge guards that can monitor open neutral, open ground, or reverse polarity. All these features come at some price. It depends upon how much you are willing to pay to keep your rig safe.


Most RVers look for easy installation features when buying a surge protector for their camper.

Here is how you can do this …

If you are looking for a unit that is very easy to install, then go for a portable one. You will only have to hook it up. On the other hand, its hardwired counterpart needs to be wired into the camper and needs a far more intense installation job.

But there’s a catch … hardwired units offer better durability and there will be no dragging on the floor with this unit either.


Weight is a considerable feature if you tend to move around your surge device a lot. Your unit needs to be lightweight and compact. However, don’t compromise by opting for low-quality materials. Your surge guard needs to come with resilience against wet weather conditions and for this reason, it must feature a tough external body.

You can look for good quality materials but also consider the lightweight and compact design of your unit. This way you can easily transport it from one place to another.

LED display

A surge protector with an LED display adds to its user-friendliness. The best part …you’ll easily read the metrics of the different things that you need to know. For example, you can read the current voltage, frequency and similar other information with LED display.

Here is what you can do …

Look for a display that is bright enough for you to read in the day as well as night time. Also, make sure that the information displayed is easy for you to interpret or understand.

Performance in bad weather conditions

If you tend to visit campsites that are located in humid climates or areas that receive a lot of rainfall, then your surge protector needs to come with weather protection too. Most of the surge guards these days come with a plastic lid to keep water away from the inside.

Take this into account if you are planning for RVing in the rainy regions. Weather changes drastically too. Maybe you have planned for a sunny outdoor afternoon, but all of a sudden you are seeing that thick cloud cover with heavy rain just around the corner. In this scenario, a surge guard with weather protection will get the job done for you.


Don’t underestimate the role of surge protector in your RV just because of its hefty price tag. It may cost you more than a hundred bucks or more but definitely can save you thousands.

Just like any other appliance, there are many brands on the market when it comes to surge protectors. They also differ in terms of features and price. As different users have different requirements, some will prefer features over price while others will go in the opposing direction. Here is the deal … make sure that you don’t overspend on those features that are not needed.

The Best RV ‘Surge Protector’ Manufacturers

There are different brands that you will find when it comes to surge protectors. However, not all of them have quality products to offer. The two major players in this market are Progressive Industries and Technology Research.

They both make surge guards and EMS units for motorhomes, travel trailers, and other tent campers. Furthermore, both these brands provide lifetime warranties on their surge protectors. However, if you are really looking for performance, then Progressive Industries should be your choice.

Here’s why … their units feature an integrated locking system and weatherproof assembly. Progressive Industries (PI) also provide field services for their hardwired units.

Technology Research (TR) on the other hand, is also a good brand but doesn’t offer as much product support as PI does. However, their products do offer durability.

Some other worth mentioning manufacturers are Camco, Hughes and Surge Guard. Their products are also good for their price but PI and TR the market leaders when it comes to surge protectors.

These two brands are a bit on the costly side too but if you are looking for the best RV surge protectors, then these are the two brands you should opt for.

Frequently Asked Questions

Do you need a surge protector for RV! Is RV surge protector necessary?

Of course, you need it. Your RV has expensive electrical devices installed in it and you have to protect them from a surge.

Why does this matter …?

In most cases, the campsite power line may be faulty and there are too many low or high voltage fluctuations in such a power source. Using a surge protector will keep all the equipment safe. And the best part … these units can also check for any open ground, open neutral or any reverse polarity too.

Will a 50-Amp surge protector work on 30-Amp?

For a quick short answer, no it won’t!

Here is how …

If you have a look at the power cord, you will easily come to know that a 30-Amp surge protector will have three prongs. Its 50-Amp counterpart has four prongs.

What’s the real story?

Your motorhome or camper is also amperage rated. Most of the Class A RVs or large Class C RVs are 50-Amp. Any smaller vehicles than this are 30-Amp. For a simple rule of thumb, if your camper features a couple of air conditioners, then it will be a 50-Amp vehicle.

So, in simple words, you can only buy a corresponding surge protector that configures with your RV amperage.

What is an EMS surge protector?

EMS or Electrical Management Systems are the advanced versions of surge protectors. As we have mentioned above that there are some types of surge protectors that can also detect open neutral, reverse polarity and open ground.

Those types of surge guards are actually EMS systems. An EMS can automatically cut the power off and turns it back on when the voltage fluctuations get reduced. These units are expensive as compared to the regular surge protectors but here’s a catch … these units are more durable and offer more top-notch performance as well.

Can you use a surge protector with a generator?

If your recreational vehicle has an inverter generator, then it is better for you to use an EMS instead of a regular surge protector. Generators that are present on motorhomes or recreational vehicles have floating neutrals.

A regular surge protector will not detect it because it’s an open neutral but an EMS will. This is where it will prove to be useful! The EMS will not let the power flow through your RV and there will be no danger associated with low or high voltages.

Which one is better, surge protector or EMS?

Most of the RV owners ask this question that which one of these two is a better option? Well, there is no definite response to this question. It’s all about your personal preferences and likings depending on your situation. Surge protectors detect voltage spikes and keep your RV safe. The best part is …the surge protectors are very cost effective.

On the other hand, EMS is expensive but here’s the deal … EMS not only detects voltage spikes but also checks open neutrals, reverse polarity, and open grounds. Now it all depends on your preferences and needs that which one of the two will you choose.
