RV Surge Protectors – Best Review and Buying Guide 2020


If you are the proud owner of a pick-up, you probably invested a lot of money to equip your car with expensive electrical and electronic equipment.

However, sometimes only one harmful electrical voltage is needed to burn out all the valuable electronic investments of your RV. Why leave it to chance?

Do I really need an surge protector for RVs in 2020?

An surge protector should be one of the most important things you should buy for your RV.

I’m sure you have friends at RV who’ve never had a problem with a power surge, but anything can happen.

In RV parks or campsites, connecting the power cable of the RV directly to a power stage is like playing Russian roulette. Put a bullet in your gun. Turn the cylinder, place the muzzle on one side of the head. Pray and pull the trigger.

Why take the risk?

Below are a few reasons why over-voltage protection is mandatory, and you should get it as soon as possible if you haven’t already done so.

Bad weather lighting – All it takes is a lightning bolt and a massive power surge to bake all your expensive electrical appliances, on-board equipment or even your entertainment system.

Why is only the zipper's best protection against voltage spikes used?

Incorrectly set outlet – it is inevitable that normally uncertified electricians will be hired to plug in the shore power outlet in parks or campsites.

If one of these electricians does not know what he or she is doing, a single fault on his or her part is enough to immediately damage any electrical equipment or wiring in your motor home.

A defective breeding ground on campsites is certainly not uncommon on breeding grounds with problems such as lack of neutrality, reverse polarity and lack of grounding.

Again, these problems will lead to unexpected damage to electrical equipment and devices that are integrated into the entire system.

Improperly maintained power outlets – Some of these unattended power outlets may cause under- and surge problems that will cause your instruments to operate below or above normal operating voltage.

And if this happens, heat generation is inevitable, which of course will lead to catastrophic damage to your RV and all electrical equipment inside.

The best zip guards for protection against stress spikes – what are the benefits?

Peak Voltage Protection – Whether you are on the road all the time or not, at some point there will be a big storm and when lightning strikes, you know that all your valuable electrical equipment and systems are well protected.

Incorrectly set basic protection – As I said before, it is not uncommon for unqualified electricians to perform an incorrectly set basic protection. Why take risks if you don’t have to?

Protection from a faulty electrical outlet as defined in – poorly maintained vans and campsites are everywhere, so there is no way you will ever have a problematic power source that will blow up your electrical systems.

Cheap investment – Buying a RV surge protector is the obvious choice if you are thinking about the money you can save at an unexpected peak or if you connect your RV to a faulty power supply.

Mind World – doesn’t play Russian roulette anymore if you connect to an electric platform on a campsite or in a bus park.

Owning one of these RV surge protectors allows you to think with peace of mind and focus on the most important things in life.

Disclaimer Note: This fact could shock you!

Most NOT RV area guards offer better protection for your RV.

So what is the main difference between a typical surge protector and a device equipped with an Integrated Energy Management System (EMS)?

Well, although it’s obvious, good surge protection usually protects against fluctuations, such as a huge power surge, especially lightning strikes and some fundamental error messages. And that’s it.

This equipment does NOT protect you from other things, such as a faulty base (open earth, open neutral or reverse polarity), improper wiring, high or low voltage, etc.

In addition, the surge protection devices (portable and permanently wired) supplied with the integrated EMS offer your carrier the same functions (depending on brand and model) as your own carrier:

  • Swing protection
  • Reverse polarity|Aterrestrial aperture|Neutral detection aperture
  • Polarity reversal|Open grounding|Open neutral protection
  • 240 V random protection
  • Incorrect display of the base
  • Display of peak voltage failure
  • Protection of air conditioning frequencies
  • and counting the numbers

5 Surge protection devices We recommend.

1. EMS PT30X RV Industrial Progressive Surge Protector EMS PT30X RV [30 Amps]

If you are looking for a surge protector that offers most, if not all, of the electrical protections of all the other surge protector products on the market, then you should put Progressive Industries’ EMS-PT30X on your shopping list.

This multifunctional arrester is guaranteed for life and comes with 1790 joules surge protector.

In addition to the EMS functions mentioned above, we are also impressed by the fact that both the EMS-PT30X and the EMS-PT50X are weatherproof (robust lexan housing and all weatherproof assemblies). And with their sturdy and reliable mounting bracket (theft protection) and robust clamping lever, they are without doubt one of the best surge protections for RVs designed for excessive outdoor use.

2. [Portable] Over-voltage protection 34950 120/240 V Full over-voltage protection [50 A]

When it comes to the production of high-quality antivirus barriers, Surge Guard (from Southwire) is the only brand on an equal footing with Progressive Industries.

4. EMS-HW50C EMS RV [Wired] EMS-HW50C EMS RV Surge protection devices [50 Amp].

If you’re like me, who’s never in a hurry to take portable electrical components somewhere, this wired RV network filter might be for you.

The EMS-HW50C is a unique effort – you can even do it yourself if you have a technical training. It has all the features of its portable EMS counterparts and, above all, is slightly less expensive.

The difference between this device and its portable counterparts is that it is UL-certified and complies with CSA (Canadian Standards Association) standards.

What makes me happy is the remote display function, which means you don’t have to step out of the van just to read the digital display in rough weather. This wired unit also comes with the 30A model and both models also have a lifetime warranty.

We particularly appreciate it that caravan owners like you do not have to constantly report your expensive surge protector in the middle of the night if it is stolen. If you travel frequently in Canada and abroad, it is a good idea to have a surge protector that meets Canadian safety standards.

5. Rigid mounting] 35550 Surge protection model [50 Amp]

35550 Hardwire model - 50 Amp. If you’re not a big fan of RH beep protectors for the progressive industry, don’t worry.

Southwire also has an equally powerful EMS network filter for your RV.

This 3850J 50 amp surge protector provides 24-hour protection against all types of harmful power sources before they can damage your RV’s electrical equipment and installations.

As with Progressive Industries’ models, the presence of a wired unit in a RV will prevent possible damage due to adverse weather conditions.

It will also bring you peace of mind, because it has no chance of being stolen at night.

Also note that the Surge Guard 35550 is an updated version of its predecessor 34560. It is also equipped with 30 amps, model 35530.

Hard cable model

  • Over-/undervoltage (input)
  • Protection of open neutrality (input)
  • Protection against wilderness
  • Reverse polarity protection (input)
  • Fault indication for voltage peaks
  • Incorrect display of the base
  • Switch-on delay (128 sec.)

  • UL list
  • Diagnosis of the power connection
  • Weatherproof

Our Rating – 8.5/10 

While this 35550 is almost as good as the Progressive Industries model, we don’t like the fact that we have to raise extra money to get a remote-controlled LCD feature that may not make sense for most pickup owners. Since this is a fixed-wired surge protector, the external LCD display must be displayed by default. What also bothers us is the lack of protection against overheating of the sockets. Besides that, we still think it’s worth it for van owners who spend most of their time on the road.

Do I need to purchase a portable or hard-wired surge protector?

As you may already know, portable impulse protectors for recreational vehicles are simply ready to use. And there’s no fighting, even if you have to put it in the parking lot.

Electrical skills and knowledge are not needed at all.

For the wired type, you may need to have electrical skills or pay extra for someone to connect to your van for you.

And, of course, you wouldn’t take the risk of stealing a surge protector.

So whatever you choose, it should depend on your technical training or your preference for a portable device that you can connect anywhere.

Conclusion – Which one should I really choose?

Progressive Industries and Surge Guard (Southwire) are the two most popular brands in the United States and their customer service is truly first class. Not to mention the lifetime warranty they offer on most of their products.

Personally, I would go to Progressive Industry if I really had to choose one.

Did you ever figure out how much money you’d have to embezzle if your van burned to the ground?

This should include all the expensive furniture and electrical appliances in your Progressive Industries RV.

The Top 5 recommended RV network protections above may save you a lot of money by preventing unnecessary damage to your RV.

What about surge protections for unknown recreational vehicles found in shopping malls? They may be cheap, but they can cause incalculable damage to your RV once your luck runs out.
