Best RV Surge Protector: 50 Amp and 30 Amp Options

I broke down the list between 50 amp and 30 amp. The prices do range from less than a $100 to over $600.

These surge protectors will keep your RV electrical system safe from most electrical inconsistencies.

I'm sure you're wondering by now "Do I need a RV surge protector?" or "Why use a RV surge protector". Many of us look at the costs associated with a surge protector and choose to put something like this off for a while.

I know we did that until we were at a state park with inconsistent voltage. We didn't have a surge protector and I could smell my electrical wires start to burn. After changing out many of the burnt wires, I realized that having RV surge protector was well worth the money.

RV Surge Protector Buyer’s Guide

30-amp vs. 50-amp RV Surge Protector

Image Source: Canva

Purchasing a surge protector is essential if you want to keep your RV safe from any potential electrical damage. To choose the right surge protector for your RV, you must first check the power cord.

If your RV?s power cord comes with three prongs, you will need a 30-amp surge protector. If it has four prongs, then you require a 50-amp surge protector.

Most camping sites have both 50-amp and 30-amp plug-ins. However, the most common plug-in is for a 30-amp surge.
A 50-amp supplies the RV with a maximum power of 12,000 watts and on the other hand, a 30-amp is limited to provide only 3,600 watts.

If your RV has a 50-amp capacity, you could also use a 30-amp cord by attaching it to an adaptor, but keep in mind that the electrical flow is less powerful than what a 50-amp cord provides.

But if your RV has a 30-amp capacity, you cannot plug it into a 50-amp cord, as the power fluctuated by the 50-amp cord will overload the RV with more than what it can take. This will ultimately cause damage. To be on the safe side use the respected capacity cords for your RV.

Using voltage analyzers and voltage monitors will add extra protection to the power to your RV.

Number of Ports

Most surge protectors come with 6 or 8 ports, but some of them have 12 ports. Buying the right surge protector with the proper required number of ports for your electrical devices is critical.

UL Seal

Checking for the UL seal is very important. UL stands for Underwriters Laboratories, which is a non-profit, safety certification company that checks the products and approves them once they meet the UL 1449 standards.

They make sure that the surge protector is a transient voltage surge compressor and will be safe to use. If you get a surge protector that does not have a UL seal, there are high chances that the product will fail to function.

Since it’s a safety device you must go the extra mile to get the best protector. This will be beneficial if you put your RV in the safest hands possible.

You might find some defective surge protectors with the seal too, but at least you are assured that they enter the standard quality. So your choice entirely depends upon the company you choose to buy from.

Safety Level

There are chances for the RV surge protector or the electrical management systems to catch fire. The possibilities are very low, but it’s best to always stay on guard. Most RV surge protectors or EMS come with a safety guard built to avoid disasters.

When the power supply is heavy, there is a massive chance for fire accidents. But with a good RV surge protector, you can potentially avoid this.

This is why you need to invest in a good surge protector for your RV. The surge protectors are equipped with LEDs and alarms that caution the user if there is an overload or lesser load. Some of them come with automatic shut-off systems. These aspects ensure the complete protection of your RV.

Joule Rating

A joule rating will show how much energy or electricity the surge protector can contain until it becomes incapable of extracting energy.

If the surge protector has a higher rating, then you can be sure that it will work longer. Also, a higher joule rating means that the devices you have plugged in have a higher protection rate against electrical issues.

It’s important to choose your surge protector by checking the joule rating. Remember, the higher the number means the more benefits and safety.

Noise Level

Sometimes when an RV has a strong surge, it makes a humming sound. In this case, check the plugins because it?s possible that the power supply has a problem.

Noises from the surge protector are common, but they aren?t normal. If you?re hearing noises, then you need to check your surge protector. Any kind of noise generated from the surge could be very disturbing, so find out what is causing the noise. 

It’s better if you drawback and check the connections. Avoid overloads.

Continuous hums or vibrations will indicate that you need to replace your surge protector. It?s always a good idea to consult an expert before making any decisions regarding the replacement of your surge protector.

Primary Vs Secondary Surge Protectors

The Primary and Secondary surge protectors differ from each other, the power flow, protection type, installation are the strong aspects that show them apart. But the only thing that is similar is that they ensure protection from power surges, lightning, and other electrical harms.

Primary and Secondary Surge protectors differ by:

Power Flow: The Primary surge protector can contain larger sources than the Secondary surge protectors. If the capacity of the Primary one is 100-200kA/1800-2000kV then the Secondary one is capable of about 40-80kA/2500kV.

Protection: Primary surge is exclusively used to protect the power from leakage. The Secondary surge works to protect overvoltage that might occur. It limits itself to protect the DC surge protectors.

Positioning: The Primary Surge protector is found with the main power supply hub while the Secondary surge protector is exclusively fixed in the input and exit lines.

Primary and Secondary protectors come in different forms. The former comes with a box while the latter is a module that is based on high lightning protection.

The users can choose the right one according to their needs. Give your RV good protection that will ensure safety and a good experience while using it.

Auto On-Off

Some surge protectors come with an automatic on-off feature, which will help keep the electrical flow in check. The emergency power off is an important feature for the RV surge protector.

If the surge protector senses that the power supply is overloaded, then it shuts off. The surge protector also shuts down if the power supply has low voltage.

This will ensure the safety of the user and the RV. The surge protector is designed to alert the user of electrical discharge and automatically cuts off the power supply when it?s potentially dangerous. So while using a surge protector you can be convinced of your safety by all means.

Weatherproofing

Image Source: Canva

A great traveling or camping experience in an RV depends highly on the weather. RV protectors are made in a way that they can resist tough weather conditions, as they are always used outdoors.

You no longer need to worry about the rain. RV surge protectors come with a plastic cover that keeps your tour device from getting soaked.

Campgrounds also have power pedestals that are protected with a cover. So, you don’t have to worry about your plugins because they are shielded to prevent water or dust from touching them.

Surge Protector vs. Electrical Management System

A regular surge protector and an electrical management system are two types of surge protectors.

The regular surge protector is the basic kind where it’s directly plugged into the power pedestal and then your RV cord is connected to the surge protector.

The RV surge protector is similar to the other surge protectors used at home.

RV surge protectors solely lookout for any overloading and keep your RV safe from excess surges of electricity.

The electrical management system does more than the surge protector. The EMS consists of several features and it protects the RV from dangerous circumstances.

The EMS will continuously check on the power flow and it will disconnect the power supply if the voltage is severely low or high. The EMS will also save your RV from reversed polarity or other issues like damaged pedestals in the campsite.

EMS provides the most protection.

Portable vs. Fixed Surge Protectors

Surge protectors come with two options: one is hard-wired and the other one is portable.

The hard-wired surge protectors are directly connected to the RV. As the hard-wired surge is always connected to the RV, it keeps it safe and protected. But the hard-wired surge is expensive and needs installation. Once it’s installed, you needn’t bother about installation again.

On the other hand, the portable surge protector is highly popular because it is easy to install. You will only need to plug in the RV cord to the electrical pedestal for electricity. Some of the portable surge protectors come with a lock system to avoid theft. You can easily replace your portable surge protector if you find any difficulty with it over time.

  2. Thanks for the great useful article. I called Progressive Industries and were very helpful. the key takeaway is that the cheaper models have limitations where you’re best to step up to the $200+ models and buy the right unit the first time! The $100- units are worth purchasing.
