Check PriceDo You Really Need a Surge Protector For Your RV?
If you have any plans of using outside power source for your RV, then it goes without saying that you’ll need a surge protector for your RV. If at all you plan to use the shore or pedestal power at the campsite, then you’ll need a surge protector.
In a nutshell, an RV surge protector:
- Protects your valuable investment (i.e., your RV and all the electronic devices aboard it)
- Ensures your own safety (prevents the possibility of fires, shocks, and other hazards), and
- It gives you peace of mind.
It takes only one bad connection to the outside power source to damage all your RV electrical appliances. And once the damage occurs, you can hardly reverse it.
You see, all the electrical appliances in your RV perform effectively at certain consistent voltage levels. When power fluctuations occur in the form of dangerously low or high voltages, they affect the functionality of your electrical equipment, cause damages, and sometimes result in fires.
But a surge protector acts as the mediator between your RV electrical items and the outside power source. It detects errors in the power supply such as voltage spikes, incorrect wiring, reverse polarity, open neutral, open ground, etc. which can harm your RV circuitry.
The protector gives its life to save your devices; it takes in the dangerous voltages to ensure they don’t reach your appliances. Your RV fully protected from any kind of power-related damages gives you peace of mind as you can enjoy your camping.

What To Look For Before Buying?
What happens when you have hundreds of RV surge protectors before you and you need to pick only one for your RV?
You get quickly overwhelmed, confused, and might end up making a bad choice.
To prevent all that, here are the MOST important things to look for in surge protectors to help you easily pick the perfect model for your RV:
Type of surge protector
Many expert RVers agree that the starting point when looking for a RV surge protector is deciding on what type of device to buy.
If you’re a starter, you might be in the dark on the different types of protectors available. But this ends today…you need to know here and now that these devices come in two MAIN categories:
- Power surge protector: these are the basic surge protectors that protect your RV against low or high spikes in electricity, thus ensuring no damage comes to your circuity as a result of unstable surges at the campsite or RV park or due to lightning strike. These units usually come with a straightforward, user-friendly design and are ideal for beginners RVers.
- Electric management system (EMS): are the secondary surge protectors that come designed to offer your RV circuitry full protection against a wide range of power related problems. They offer protection to your appliances against high and low voltages, high and low-line frequencies, open neutral, open ground, faulty wiring, and overheating plug/receptacle.
Due to their higher level of protection, the EMS units usually come at a higher cost. We recommend these type of protectors to full-time campers who want to enjoy the ultimate peace of mind at all times.
Compatibility
Another important factor to consider when shopping for your RV surge protector is whether the unit you get will actually work with your RV electrical supply service.
The two most common electrical services for RV include 30 amp and 50 amp.
The perfect surge protector for you should match your RV electric service. That is, a 30 amp RV surge protector goes with a 30 amp RV electrical supply service and a 50 amp unit goes with a 50 amp RV electrical service.
That’s going to be easy to choose, right?
But keep in mind that you might get confused about your RV’s electrical service.
To avoid this, we recommend you to inspect the type of plug that comes with your RV... if it features 3 pins, then it’s 30 amp. If it has 4 pins, that’s a 50 amp electric service.
Also, keep in mind that smaller RVs, with less electrical appliances, usually feature a 30 amp service.
Still at it, the modern RVs usually come with 50 amp service, unlike the older models that come with 30 amp service.
Energy absorption/dissipation (Joules rating)
You’re probably aware that surge protectors don’t last forever.
However, how the longevity varies from model to model.
If you want to know how long your device remains functional, then you need to check its joule rating (which simply indicates the unit’s energy absorption/dissipation capabilities)
Theoretically, a higher the number of joules means greater protection and longer lifespan. Additionally, a higher joule rating means the device can easily dissipate heat and preventing overheating.
With that said, a device rated 200- 400 Joules will deliver decent protection.
If you want a surge protector that offers greater protection to your RV rig, and minimize overheating, look for one that has the higher Joule rating—anything from 600 Joules and above.
LED Display
Though most RVers tend to overlook this feature, it’s a great one to have in your surge protector.
A protector that comes with LED display helps relay information to you about the stats and metrics of the power source your RV is connected to. This helps further ensure safety and efficiency of your electric items.
Moreover, these indicators help you easily evaluate the working status of your protector. Most units feature a 3 color indicator system. Green means the unit is working well. Red issues an alert that the system is broken down and requires replacement.
When looking for a surge protector, make sure it comes with a bright indicator to ensure you don’t miss a single alert or warning.
Still at it, some units come with an easy to read digital LED display that shows you the status of the power supply you’re using.
Portable or hardwired protector?
You’ll also need to decide whether to go with a portable or hardwire surge protector.
The portable model is the most common among RVers and involves connecting it to the pedestal power at the campsite and then connecting your RV cable to it.
The good:
- It’s incredibly easy to install (plug and play type)
- Easy to replaced
- Can be used with different RVs
- Comes at an affordable cost
The bad:
- It can be easily stolen
- When using a power outlet that’s too low, you might need to leave you protector on the ground. This might not be a wise idea if the ground is wet
The permanent or hardwired model on the other hand is designed to be installed- wired- inside your RV. You integrated into your recreational vehicle wiring system to make it part of your RV.
The good:
- Cannot be stolen; it’s wired to your RV
- No need to worry about leaving it on wet ground
- Stays on each time you get connected to a power supply
The bad:
- Come at a higher cost
- More challenging to shift from one RV to another
- Some installation required
Which one to buy?
In our opinion, the ideal model to buy will heavily depend on your preferences. But make sure you understand the highlights and downlights of each model before making a final decision.
Cost
One last thing you should keep in mind when shopping for a surge protector is your budget.
You don’t expect all these units to feature the same pricetag; some are pretty cheap while others come at higher costs.
Portable models usually cost less than the permanent models. Units that offer basic protection cost you less than those that offer you a higher level of protection.
If you’re on a tight budget, you can get an entry-level protector for less than $100 bucks.
Most of the top-rated portable and hardwired RV surge protectors usually fall in the $100 to $200 price category.
Spend anything above $200 and you’ll take home an advanced protector characterized by greater quality and a higher level of protection.
Other considerations:
- Warranty: a protector that’s backed by a warranty can assure you of the product quality. Some manufacturers even extend the warranty to all the appliances attached to the protector should a charge go through.
- Brand: if you don’t want to get disappointed by a surge protector, consider getting a unit from reputable brands whose products rise above the rest in terms of performance, reliability, and quality. Some of the top brands you might consider include Progressive Industries, Camco, and TRC.
- Weatherproof construction: if you go for a portable protector, make sure it has a weatherproof design to shield it from various weather elements that might affect its functionality.
- Automatic shutoff/restart: units that automatically shut off in case of any threat to your appliances give you peace of mind as you can always rest assured that no harm will come to your RV. Likewise, a unit that automatically restarts itself when power is restored is easier to operate.
How Do RV Surge Protectors Work?
We all know that a surge protector helps protect your RV electronic devices from power surge and other electricity problems.
But how exactly does it do so?
To understand its operation path, you first need to understand what a power surge is all about.
A power surge happens when the voltage flow significantly rises high above the normal level of 120 V (for United States). Your RV appliances are designed to run at 120V. And a rise in this voltage, i.e. a surge, can have damaging effects on them.
This is where the surge protector comes to your rescue!
The device acts as the mediator between the power outlet and all the appliances plugged into it. When a voltage spike occurs, the protector diverts the excess electricity into the grounding wire of the outlet.
A typical RV surge protector comes fitted with a metal oxide varistor (MOV) that’s tasked with diverting the extra voltage. And in so doing, the protector ensures these excess voltage doesn’t reach your appliances and damage them.
The MOV features three main parts—a piece of metal oxide surrounded by 2 semiconductors.
The semiconductors have variable resistance that’s dependent on the voltage coming from the power source. When the voltage is too high, above the expected level, the electrons in the semiconductors flow in a manner that creates lower resistance. The opposite happens when the voltage becomes too low; the semiconductor electrons flow in a way that helps create higher resistance.
When the voltage is at the correct levels, the MOV does not do anything. When the voltage gets too high, the MOV conducts a lot of current as a way of taking (and eliminating) the excess voltage.
On diverting the extra voltage into the MOV and to the ground, the voltage flow gets back to normal level, making the MOV resistance shoot up again. In other words, the surge protector diverts the extra current while allowing normal current levels to flow through.
NOTE: The MOV is sacrificial in that it burns with repeated power surges. That’s why RV surge protectors have limited lifespan and stop functioning after taking in several surges (determined by a given unit’s Joule rating).
As you might have noted in our RV surge protector reviews above, these devices come with an indicator to alert you when they stop functioning to let you when to replace them with a new model for the continued protection of your appliances.
Where To Buy a Surge Protector?
At this point, you have already decided that you need a surge protector to safeguard your RV electronic devices against damages. But one more thing is bothering you…where can you buy the best RV surge protector?
Consider these options:
- RV supply store near you: one place where you can get a good surge protector is checking if there are any RV supply stores in your locality. When you find one, use our buying guide above to help you pick the perfect one for your RV. The dealer might also offer a helping hand when choosing the right protector.
- Online stores: another place where you’ll get a good surge protector is the online stores. This can be an online-based RV supply store or general store like Amazon, Walmart, etc. Unlike the physical stores, these online stores usually have a review section where RVers who have previously used the protector you plan to buy give their experience using it. This can be helpful firsthand info to help you gauge the performance of a unit and whether it’s worth your money.
Which of these options do you think will be convenient for you when purchasing a surge protector for your RV?
Frequently Asked Questions
1. What is the best surge protector for my RV?
It’s not easy to single out a specific surge protector for your RV. This is because there are multiple of these units on the market today. Plus, the right one for you will depend on a number of factors as we discussed in our buying guide.
The right protector for your RV should be compatible with your camper electrical service. It should also offer an excellent level of protection, be easy to install, and come with convenient features like indicators or LED display.
Above all, it should match your budget needs.
2. Do I need RV surge protector when using a generator?
Yes, it’s absolutely possible to use a surge protector with your RV generator. However, it’s not always necessary as you might experience some challenges with this kind of setup.
For instance, if you hook a protector to a portable generator, it will keep displaying open ground and will not allow power to pass through.
The way we see it, generators generally produce quite low voltages. As such, you don’t have to worry about surges occurring, which renders a surge protector unnecessary.
3. Can I use a 50 amp surge protector on a 30 amp RV?
While you might come across some Rvers recommending you to use a 50 amp surge protector on 30 amp RV, we don’t encourage you to do it.
After all, the main reason you’re using that protector is to act as a mediator between your RV electric system and the power supply should a voltage spike occur. And for this reason, your protector will only work when you match it to your RV electrical service.
For you to enjoy the full benefits of a surge protector, just use a unit that’s compatible with your RV electrical supply service. Check our RV surge protector 50 amp reviews and 30 amp reviews in our reviews guide.
4. What’s the average lifespan of a surge protector?
How long a surge protector lasts depends on how much extra voltage it can absorb, which is expressed in terms of Joules.
The higher the Joule rating of a given unit, the more electrical surges it can hold up, and the longer it can last. The longevity can also depend on the brand quality.
With that said, you should make a point of replacing your surge protector every 3-5 years. If you use your unit more often, then you might have to replace it even earlier.
But it doesn’t always have to be after 3-5 years. If your unit’s indicator system shows that your protector is no longer functional, then a replacement is necessary.
5. Are the surge protectors waterproof?
Yes, surge protectors are waterproof…BUT not all of them.
Nearly all the portable protectors usually come with a weatherproof design to help shield them from weather elements. This is mainly because they’re meant to be plugged on the pedestal power outlet and left outside your RV, where they can get exposed to all sorts of adverse weather conditions.
If you plan to go for a portable surge protector, make sure it comes with a weatherproof shield or housing to enable you to use it in all weather conditions.
For permanent units, weatherproofing is a non-issue since they’re always inside your RV.
Final Verdict
Blindly connecting your RV to a campsite pedestal power source without testing for mis-wiring or reverse polarity, electric surges, open ground, open neural, and other power supply issues can cause damage to your RV electric equipment and force you to spend lots of money in replacement and repairs.
But using the best RV surge protector helps ensure that only safe voltage reaches your appliances, enabling them to run effectively and safely.
Whether you’re a full-time RVer or plan to go RVing for a few days, we highly suggest that you get a surge protector for your RV today. The device costs you a few hundred bucks but saves you thousands and thousands of bucks.
