Quick View of 50 Amp RV Protectors & Our Top Picks

There are lots of surge protectors on the market even online shops. All are not for use in a long time. In my research, I looked at over 30+ most popular models of 50 amp surge protectors on Amazon.

From these, I have chosen the top 10 most popular surge guards for your 50 amp RVs. Each model was chosen for its great features, good design, high customer ratings, and reputable brand name. Therefore, you can pick whichever you like. Below is a quick view of the top 10 RV protectors with our best pick’s models and brands.

Types of RV Surge Protectors:

Currently, RV surge protectors are available in three different types. Depending on your needs and the level of protection you require, you will know which is best suited for you and your RV.

  • Single-phase: The first, and a simplest surge guard unit is the standard single-phase RV surge protector that plugs into an external outlet, though some may have an extension cord that makes them even more functional.
  • Triple Phase: The next one is the triple-phase surge protector. This type of surge protector has three (3) separate electrical lines; one for power, neutral, and ground. It protects the RV from surges, as well as noise and unwanted power that can harm or degrade your RV’s electrical system if not properly protected.
  • Multiple Phase: The most expensive surge protector, but also the strongest and best-suited to protect an RV against any voltage surge, is the multiple-phase unit. This type of RV surge protector provides three (3) independent power lines, plus a ground line. Additionally, multiple-phase surge protectors are the only surge protectors designed to guard against all power surges or noise problems.

Why do you need a 50 amp RV surge protector?

A 50 amp RV surge protector is necessary because multiple devices are consuming more than the limit of your 50 amp cord on your 30 amp RV’s electrical system.

A 50 amp surge protector protects your RV’s electrical system from damage caused by a brownout, blackout, or power spike.

When you connect multiple devices to your RV’s 30 amp system, you exceed the maximum amperage of your cord.

If you plug in two 15 amp devices into your 30 amp system, you are using half (15 amps) of your available power before any other device is turned on. When you plug in another appliance, such as a microwave or coffee pot, the line will go dead. In this case, you need a 50 amp RV surge protector.

The majority of RV manufacturers recommend using your generator to power your air conditioner (12,000 – 15,000 watts) or microwave (more than 12,000 watts). Hence, a 50 amp RV surge protector is needed for handling high-power RV devices.

Also, a 50 amp surge protector will protect your air conditioner and microwave from being overvoltage if the power source is faulty.

Also, a 50 amp surge protector will provide the following benefits:

  • Protects your RV’s electrical systems from high-power devices like an air conditioner or microwave oven.
  • Protects your RV’s electrical system from damage caused by power surges (brownouts, blackouts).
  • Protects your RV from over-voltage damage caused by a bad power supply.
  • A 50 amp surge protector should be wired to your RV’s 30-amp electrical cord between the power supply and your RV. If you have a 50-amp cord, you should plug the surge protector directly into your RV.
  • The 50 amp surge protector is a separate unit from your 30 amp surge protector.

What should I look for when buying an RV surge protector?

When buying an RV surge protector there are a few things you should consider. When you follow this advice, you will be more likely to buy a quality product that meets your electrical needs and keeps your RV equipment safe.

UL certification:

An overloaded surge protector will not do much good if it fails due to a power surge. UL (Underwriters Laboratories) tests products to ensure they meet a minimum standard of safety and quality.

Some surge protectors will carry the UL symbol, but not all, so you should always ask. If the surge protector is not UL-certified, the company cannot honor its warranty.

  • Protection of life and property from fire and electrical hazards.
  • Enhanced value in terms of performance, reliability, durability, and safety.

Joules Rating:

A higher joules rating is better. The joules rating indicates how much energy a surge protector can handle before it fails. The higher the rating, the more expensive the unit will be. Therefore, I recommend that you purchase an RV surge protector with at least 800 joules. It will protect your appliances.

If you have a surge protector with fewer joules, it’ll be cheaper but failure is more likely and that means that your RV appliances will not be protected. The easiest way to determine how many joules your surge protector can absorb is by looking at the label. 

Amp Rating:

In electrical theory, an electrical current measurement tells us how much current can safely flow through your wire. In general, the higher the amp rating, the thicker the wire needs to be. 

Having a 50 Amp RV should be no problem, but increasing the power source may be necessary to protect your camper. So you should increase the size of the wires. So before purchasing a surge protector, make sure it has an adequate amp rating for your RV.

Power surge capability:

Your 50 amp power surge protector will protect you against voltage spikes caused by larger appliances like air conditioners, heaters, ovens, and microwaves. It’s important to check the power supply of these appliances before plugging them into an electrical source.

If you have more than one appliance, you should check the total amps to ensure that your RV surge protector will accommodate the extra power.

Portable vs Built-In:

There are two types of RV surge protectors. One is a portable RV surge protector and another is a built-in RV surge protector. The portable option allows you to move the unit from one location to another within your RV, which is the option that I recommend.

You can place it near your electrical panel or at the front of your RV, where power cords are most likely to be plugged in. This way, you can easily monitor your appliances and ensure that they are not overloaded.

A built-in RV surge protector is only located in one location of your RV. This option may be better if you have a generator or inverter that is hard to access. So you should consider, which you want before making a purchase.


Several RV surge protectors have alarms that sound if they detect any abnormalities in the electrical current. This type of RV surge protector is the only one that has a row for you to set up your voltage and current. But keep in mind that if your appliances overload, it won’t be able to protect them.

Thus, it is a good idea to purchase a surge protector with an alarm. You will be aware of any potential problems with your appliances before they occur.


Lighting is another great feature included in some surge protectors. There are some surge protectors for RVs that have a green light that indicates proper operation. If it is red, you should not plug any appliances into the surge protector until the problem is fixed.

Some 50 amp RV Surge Protectors have a red light that turns on when it detects any abnormality. If the problem persists, the light will stay on and you should consider turning off that particular circuit until it is resolved.

It is also a good idea to purchase a surge protector with a lamp on it, as it will alert you when there is a problem. This will reduce the risk of serious damage to your appliances when an electrical problem occurs.

Surge Protector Response Time:

A surge protector’s response time measures the time it takes to sense a voltage spike and shut off the power. The faster it can shut off the power, the less damage it will cause to your appliances.

So, a fast response time of a surge protector is another reason that you should consider it. It will ensure that your appliances are not damaged by shutting off the power in time.

Other important factors to consider

Low voltage:

It is very important that your surge protector can automatically shut off power when low voltage is detected. If your surge guard lacks this feature, you cannot use it for low-voltage situations.

Therefore, before buying a surge protector, make sure it is equipped with this feature. If the system doesn’t shut off power on low voltage, you have a risk of overloading your RV’s electrical system.

Display or no display:

You should consider whether you want an LCD display on your surge protector. Display surge protectors typically cost more than non-display models.

Some displays also show voltage and current. The same information can also be obtained from surge protectors with built-in alarms and lamps. Therefore, you can purchase a surge guard unit with indicator lights and an LCD display.

Electronic equipment insurance:

The majority of RVers are now wondering how to get RV insurance? Well, here is the answer. Many surge protectors offer you insurance against equipment damage and electrical issues.

For example, Progressive Surge Protection covers any appliances that are damaged because of an electrical surge. The policy will cover the full replacement cost of the appliance, as long as it was safely connected to a Progressive Surge Protection system. Therefore, you can keep this in mind when purchasing a surge protector.

Tips Before You Plug RVs Into Your 50 amp Surge Protector

Before you plug RVs into a surge protector, you should carefully check these things if you do not have enough knowledge about electrical things.

1. Ensure that the voltage of the power source is at least equal to or higher than one-fourth of the RV’s voltage. For example, if your RV is a 12-volt system, you should plug it into a power source with 120 volts or higher.

2. A surge protector cannot handle any surges from the power source, so if the power source has any electrical problems, it will just pass through to your RV.

3. The surge protector should have a clear label saying “No Equipment Ground”. If the label says “Equipment Ground” or has a green wire, it can not be used as a surge protector and is very dangerous to use with RVs.

4. Do not plug extension cords into surge protectors. It is very dangerous to use surge protectors with extension cords, and it will void the warranty.

5. If you have an Aluminum Alloy Trailer, a Travel Trailer, or any other type of specific instructions, check your owner’s manual.

6. The surge protector must be in good condition when you plug in RVs into it, so check for any damaged material.

7. Check your surge protector at least once a month with a multi-meter to make sure it is still working properly. You should also read your owner’s manual for information on how to do this.

8. Make sure the power source has the right voltage and ampere for RVs, otherwise they will be damaged quickly.

9. A lot of experts agree that mis-wiring is one of the primary causes of RV fires. Therefore, you should check your wiring. You should consult an RV specialist or someone with a lot of experience with electrical components if you aren’t sure how to check it.

10. If the voltage is too low, your appliances will not run efficiently, and they may even be damaged. You should check the voltage regularly.

  1. My RV is wired for 50amp service. My question is if I buy a 50 amp surge protector and in occasion plug it in to a 30 amp or even 15 amp service which is the only available power at the campsite will I still get the full protection benefits of the 50 amp surge protector? Thanks Norm…

    • The devices will be fully protected; however, it is recommended that you should use a surge protector that is compatible with the power of your RV devices. For example, if your RV device requires 30 amps of power, you should use a surge protector that has the capacity to handle 30 amps.

  2. We bought our first motorhome last summer. The motorhome has been used and we have had intermittent issues with the fridge shutting off. After researching online, the standard of nutrition at campsites was a typical theme. I purchased this air conditioning after comparing some makes and models. I have not had an accident since! No lights flickering, no resetting the fridge, nothing. The unit indicates what proportion of current and voltage you’re consuming at any given time. Very easy to use. it has been worth every penny up to now. I might die again within the blink of an eye fixed.
