A Guide to Choosing an RV Surge Protector

When it comes to maintaining and safeguarding your RV, ensuring electrical safety should be a top priority. A surge protector is an essential device for protecting your RV’s electrical system from power surges and fluctuations. But if you’re not familiar with electrical systems, choosing the right one might be a bit of an arduous task. Fortunately, you don’t need to be a trained electrician to choose a surge protector for your RV. This guide will walk you through the key considerations in selecting the best option for your needs.

Do RVs Have Surge Protectors Already?

New RV owners might wonder if surge protectors are already built into their vehicles. The answer depends on the make and model. While some high-end RVs may include built-in surge protection systems, most do not. Even among those that do, the protection provided might be basic and insufficient for handling severe power spikes or miswired pedestals at campgrounds.

Without a dedicated surge protector, RVs will be left vulnerable to potential electrical issues caused by unstable power sources, leading to damaged appliances, compromised wiring, and costly repairs. Regardless of whether your RV has basic protection or none at all, investing in a quality surge protector is a wise decision.

Are Surge Protectors Something You Can Wait To Buy?

The short answer is no. Since RV surge protectors are necessary to protect electrical systems from damage caused by surges, spikes, and wiring issues, waiting would be a bad idea. RVs frequently need to connect to external power pedestals at parks and campgrounds. Anytime you do, you’ll be putting your RV at risk of encountering unreliable or miswired sources, which could lead to a short. Here are a few examples of factors that can cause power surges:

• Lightning strikes that cause voltage spikes.
• Power grid failures that lead to unstable currents.
• Improper wiring or faulty connections at campground hookups.

While these scenarios aren’t overly common, you never know when they could happen, which is why waiting to buy a surge protector is unwise.

Even outside of the fact that surge protectors act as gatekeepers, blocking excessive voltage from damaging your electrical system, they provide other useful advantages that you could be taking advantage of. Many surge protectors come with diagnostic capabilities to test the power source and alert you to potential wiring faults or low-voltage issues. This makes them critical for ensuring the safety and longevity of your RV’s electrical components.

What Types of Surge Protectors Are There?

Now that you know that you shouldn’t wait to buy a surge protector for your RV, it’s time to learn how to choose one effectively. This starts by understanding which types are available to you. Typically, RV surge protectors generally fall into two main categories based on their level of functionality, so here’s what you should know about them.

1. Basic Surge Protectors

Basic surge protectors provide minimal protection, but they provide the basics by protecting your vehicle from voltage spikes. They are a cost-effective solution for RV owners who want a simple line of defense but may not include additional features like diagnostic tools or hardwiring capability.

2. EMS (Electrical Management Systems)

Electrical Management Systems (EMS) take functionality to the next level. They not only protect against voltage surges but also monitor for various issues, such as:

• Open ground or open neutral
• Reverse polarity
• Low voltage
• High voltage

EMS devices shut off the power flow to your RV when they detect potentially harmful conditions, making them a more robust and comprehensive solution.

Additionally, there are deeper categories for these types of surge protectors, which are determined by their design and installation type:

• Portable surge protectors are plug-and-play devices that connect externally to the power pedestal and your RV’s power cord. These are ideal for flexibility and on-the-go protection.
• Hardwired surge protectors are installed permanently inside the RV and protect the entire electrical system from within. They often require professional installation but eliminate the risk of theft or weather exposure.

Which Features Should Yours Have?

The most important thing to know about this decision is that it involves understanding your unique needs. That way, you can ensure that the device you select is equipped with all the right features. Here are some key considerations you should take into account before making a purchase.

1. Amperage Compatibility

Your RV will either have a 30-amp or 50-amp electrical setup. Select a surge protector that matches your RV’s requirements. Using the wrong amperage can result in equipment failure or insufficient protection.

2. Weather Resistance

Since many surge protectors will be exposed to the elements, ensure your device is weatherproof or comes with protective covers. This is especially important for portable models that connect outside.

3. Joule Rating

The joule rating determines the surge protector’s capacity to absorb energy. A higher joule rating indicates stronger protection against power surges. For RVs, look for ratings of at least 2,000 joules or more for adequate protection.

4. Diagnostics and Indicators

Advanced surge protectors come with LED displays or indicator lights that show real-time updates on the status of the power source. Look for diagnostic features such as:

• Voltage readings
• Fault detections
• Alerts for unsafe conditions

5. Auto-Shutdown Feature

Premium surge protectors and EMS devices have auto-shutdown capabilities. This means the device will automatically disconnect your RV from power if it detects unsafe levels of voltage or other electrical hazards.

6. Durability and Design

Durability matters, particularly if you travel frequently. Choose a surge protector constructed from heavy-duty materials that can withstand wear and tear. Compact designs may also save valuable storage space in your RV.

7. Warranty

Many reputable brands offer extended warranties for their surge protectors. A strong warranty adds peace of mind and ensures you’re covered in the rare event of a malfunction.

How Do You Come to a Final Decision?

Selecting the right RV surge protector ultimately comes down to understanding your RV’s electrical requirements and travel habits. Here are some final things to keep in mind that should help you narrow down your search:

• If you frequently visit campgrounds with unknown or unreliable power sources, invest in a high-quality EMS for comprehensive protection.
• If you prefer simpler solutions for casual or occasional RV trips, a basic surge protector is a solid budget-friendly choice.
• Portable models are great for flexibility, while hardwired systems offer convenience and reduced risk of theft or disconnection by others.

Be sure to research and compare different brands and models. Look for trusted reviews and consider factors like ease of use, customer support, and cost-effectiveness. The initial investment in a quality surge protector is minor compared to the potential cost of repairing damage from an electrical surge. Taking this step to protect your RV’s electrical system is crucial so you can focus on enjoying the road ahead, worry-free.
