What is an RV Surge Protector?

Best RV Surge Protector - Protector Surge Guard 34850 Portable Model

To understand a surge protector, you first need to comprehend what an electrical surge is.

An electrical surge is an intense, short-duration voltage increase that travels through electrical wiring which transmits energy. The most common causes for electrical surges include lightning, power outages, tripped circuit breakers, etc.

A surge protector is a device designed to protect other devices from damage-causing power surges. It may have a long power cord or it may plug directly into the wall, and it usually has multiple outlets for connecting equipment. Whether it is a charging pedestal, your house, or somewhere else, just attaching a surge protector to the charging unit ensures there are no surprise short circuits to ruin your day.

In short, a surge protector is an insurance policy for all the stuff in your RV. And of course, your family!

Types of RV Surge Protectors

When you step out to buy an RV surge protector, you’ll find two basic types.

Portable – Portable surge protectors are the most basic ones being sold out there. These are usually devices that you can plug directly into the charging pedestal. They not only protect you against surges but also allow you to know if the pedestal is wired properly.

Hardwired – Hardwired surge protectors are fitted inside your RV and can be monitored through a dedicated panel. One of the benefits of having a hardwired surge protector is that you don’t have to worry about having it knocking around in your storage compartment since it is properly fitted; it is also safe from external elements like rain and excessive heat at the pedestal.

Hardwire VS Portable RV Surge Protectors

As already mentioned both kinds of protectors come with the basic difference that portable surge protectors are handier and can be plugged into any charging pedestal you can find. On the other hand, hardwire surge protectors are fitted inside the RV and are thus more stable and protected from the elements as well as from theft.

Another major difference between the two devices is that portable surge protectors can safeguard your RV from external surges and issues. They don’t have much control over internal mishaps. However, that’s one area where hardwire protectors have you covered. They can safeguard you from internal faults as well as external issues.

And lastly, hardwire surge protectors are generally heavier and deliver more power (in amp) than portable surge protectors.

  • Portable surge protectors are handier
  • They are more lightweight
  • They don’t need any installation
  • Hardwire surge protectors are protected from the elements since they are fitted inside
  • They deliver more power
  • They safeguard against external as well as internal faults
  •  Portable surge protectors cannot safeguard against internal faults
  •  You might accidentally leave them behind on the pedestal
  • Easy to steal unless you lock them Hardwire RV Surge Protectors
  • Hardwire surge protectors are heavier
  • They need to be installed

How RV Surge Protectors Work

When out on the road, you find numerous charging pedestals at common pit-stops. These pedestals once erected stand there for years. They endure the elements of nature day in and day out which is why they may often get damaged internally. Damaged charging pedestals become prone to power surges or power spikes which are increased flow of voltage for short time duration, sufficient to fry anything that’s connected to them. Imagine how much damage such pedestals can cause to your RV when you innocently plug it in for charging.

In order to prevent such an occurrence, smart trippers use surge protectors. Surge protectors when attached between your RV’s charger and the charging pedestal’s charging outlet break the flow of energy to your vehicle in case there is a power surge and divert the extra electricity into the outlet’s grounding wire. In this way, your RV stays safe from fire hazards and short circuits.


When travelling with your family in your own RV, one of the most critical aspects is ensuring the safety of your dear ones as well as your vehicle. Thus, carrying a portable surge protector or having a hardwired one fitted into your RV is a must. This will ensure your trip stays pleasant and you stay away from unwanted fire accidents.

How to install an RV Surge Protector

Best RV Surge Protector - Portable RV Surge Protector

Note: This installation procedure is applicable to hardwire RV surge protectors. Portable ones don’t need any installation.

First things first, you don’t need to be a mechanical genius to do this. Just enough household electrical knowledge will get you through.

Hardwire surge protectors come with a display panel which shows the amp reading, the hertz, and the voltages and also indicates if there is something wrong. The panel can be fitted at a convenient location on the RV’s dashboard area or anywhere else. You also get a cable that looks like a telephone cable with the whole setup to connect the surge protector and the display.

Some people prefer to install the surge protector in the same compartment as their power converter. This is done for the convenience of tackling with fewer wires and sockets. In this example too, we’re doing the same.

Before beginning the installation, unplug the trailer from the power outlet and remove the battery because you don’t want to accidentally electrocute yourself. Thereafter, follow the below-mentioned steps:

RV Surge Protector – Installation Steps

Step 1: Cut the main 30 Amp wire (or the one that your RV is currently running on) at a convenient spot and peel it about 3-4 inches back. Do this on both ends of the cut you’ve made.

Step 2: Consult the user manual of the surge protector to understand the sides where the power should be coming in and going out from. Then make the appropriate outgoing connections between the cut cables and your surge protector cables (you’ll have to unscrew the lid of your surge protector to see what wires are inside).

Step 3: Attach the grounding connections. Then make the incoming connections and remember to use the sensor within the surge protector which goes over the lead.

Step 4: Now plug in the telephone-like cable into the surge protector and attach it to the display. Now when you plug in the power to your RV, the display should start reading the incoming power, volts, hertz, and indicate if there are any errors.

Step 5: Lastly, attach the display to a convenient location and you should be good to go!

Buyer’s Guide –Best RV Surge Protector

Buyers Guide Icon

After digging deep into the basics mentioned above and going through our list of the top picks, are you ready to pick out your favorite RV surge protector? Good! But before you put your money on the line, take care of the below-listed factors that you should definitely consider. Keeping these factors in mind will help you make the best buying decision.

Power Rating (Joules)

The power rating or joules rating of a surge protector indicates the level of protection that it can offer. Whenever there is an excessive flow of electricity caused by power spikes, the surge protector should be able to dissipate the heat and save your rig. The higher the joules rating of a surge protector, the more capable it will be to fit fire harm and damages.
With the abundant variety of devices available online as well as in the open market, it’s very easy to get stuck with cheap knock-offs if you’re out buying a surge protector for the first time. One way of making sure you buy a genuine product is to ensure that it is UL certified. UL or Underwriter’s Laboratory offers a seal for genuine products and the ones that have it are the best ones you can get out there.

Extra Factors

Load Capacity
It is crucial to consider how much electrical load your device can handle. Every device needs some amount of electricity to perform its intended function. But how much electricity can it comfortably handle? Ensure that you check the load capacity of the surge protector you’re considering and pick that protector, which is suitable for your use. Its load capacity should make it less prone to overheating, fire and other electrical issues.
In addition to considering the above-mentioned factors, you must pay attention to the cost, for obvious reasons. The surge protector you pick should be cost effective and should fit your initial budget. That certainly doesn’t mean that you straightaway go for the cheapest buy. All you need to do is compare the prices of all the models you like, weigh the pros and cons carefully and then make a buying decision.


To wrap it up

RV surge protectors are an absolute must for you if you like to be on the road with your rig and your family. These devices can prove to be lifesavers in adverse situations. Unless you want the carefully picked out appliances and furniture in your RV to get fried because of an electrical surge and short circuit, you need a surge protector to dissipate power spikes whenever you plug in your RV for charging.

In our opinion, the Smart Surge Protector from Progressive Industries is the best device you can get for safeguarding you against unexpected power surges. It is capable, affordable, and quite robust. Avoid going ahead with a device only because it is cheap; after all, your high-risk appliances are worth protecting.

That’s all from us here folks! Have a safe trip and keep our pointers in mind.

Happy camping!
