Do You Really Need a Surge Protector?
Power Surges
Power surges occur when there is a sudden increase in electrical voltage. This can lead to devices receiving a burst of power that they cannot handle, which may result in damage. Common causes of power surges include lightning strikes or issues with the electrical grid, especially in campgrounds where connections can be unreliable.
To protect equipment, it is important to choose a surge protector with a high joule rating. This rating indicates the protector’s ability to absorb excess energy. A minimum of 2000 joules is recommended for most RV applications, but higher ratings offer even better protection.
Low Voltage
Low voltage issues arise when the electricity supplied to the RV is less than required. This can lead to appliances malfunctioning or becoming damaged if it happens consistently. A surge protector equipped with low voltage protection is essential for situations like this.
Many modern surge protectors will automatically shut down when they detect low voltage, thus safeguarding the RV’s electrical system. It is wise to choose a model that offers comprehensive protection against both high and low voltage scenarios to ensure smooth operation.
Open Ground
An open ground condition occurs when a ground wire in the RV’s electrical system is disconnected or absent. This situation poses significant safety risks. Without a proper ground connection, the risk of electric shocks or electrical fires increases. Additionally, ungrounded systems may lead to equipment failure or malfunction.
Using a surge protector that can detect ground issues helps ensure safety. Many devices come with indicator lights to signal when the ground connection is compromised. If this light is activated, it’s crucial to address the underlying problem before continuing to use electrical systems.
Open Neutral
An open neutral situation is similar to an open ground, but it pertains to the neutral wire specifically. If the neutral wire is disconnected or broken, it can cause uneven voltage distribution, which can damage electronics within the RV.
Like open ground indicators, surge protectors often have lights to signal open neutral issues. If such a light is on, it warns the user that there is a problem with the electrical supply. Taking action, such as consulting campground staff, is important to rectify the situation and ensure safety.
By understanding these potential risks, RV owners can make informed decisions about surge protection to keep their equipment and themselves safe while enjoying their journeys.

Things to Consider
30-Amp RV Surge Protector Or 50-Amp RV Surge Protector?
Choosing the right surge protector depends on the electrical needs of the RV. For smaller RVs, like travel trailers and campers, a 30-amp surge protector is usually sufficient. Travelers should ensure that their RV’s electrical demands align with the 30-amp capacity before making a decision.
For larger RVs or those with greater electrical needs, a 50-amp surge protector is the better option. This is essential if the RV is equipped with appliances that consume more power, such as air conditioning units or washing machines. Selecting the right amperage ensures adequate protection and performance.
Portable or Hard-Wired?
The choice between a portable surge protector and a hard-wired model primarily depends on personal preferences.
Portable surge protectors are user-friendly and convenient. They can be easily transported and used with different RVs. If a portable unit malfunctions, it can be replaced without much hassle.
On the other hand, hard-wired surge protectors are directly installed into the RV, making them more secure against theft and weather damage. They are ready to use as soon as the RV is connected to shore power, eliminating the chance of forgetting it at a campsite. Installation can be complex, but once set up, they offer hassle-free operation for the long term.
Joules Ratings
The joules rating indicates how much energy a surge protector can absorb before failing. This rating is crucial for the protection of the RV. Higher joules ratings generally deliver better defense against power surges, similar to having a stronger shield against an attack.
For optimal safety, buyers should look for surge protectors with a joules rating of at least 1000 joules. Ratings above 2000 joules are more desirable, and those exceeding 3000 joules provide even greater assurance during extreme electrical events, such as lightning strikes.
EMS VS Surge Protector
Surge protectors and Electrical Management Systems (EMS) serve different purposes. Surge protectors primarily shield the RV’s power supply from voltage spikes. They are simple, cost-effective, and suitable for those who need basic surge protection.
Conversely, an Electrical Management System offers comprehensive safety. It provides protection against low voltage, open ground situations, and other electrical hazards. For those looking to safeguard expensive RV equipment, investing in an EMS can be worthwhile.
While surge protectors are adequate for minimal needs, an EMS is a more complete solution. With its extra features, an EMS can prevent multiple types of issues, ensuring better overall safety for the RV and its electrical systems.
Our Verdict
When preparing for RV adventures, surge protection is a must. Given the significant investment in an RV, often reaching six figures, along with valuable equipment inside that could cost thousands, having a surge protector is essential. Without it, the risk of damage from power surges is too great.
For those seeking a reliable portable option, the Southwire Surge Guard 34951 stands out as an excellent choice. This surge protector combines great value with user-friendly features, ensuring peace of mind on the road.
If a hardwired solution is preferred, the Hughes Autoformer Power Booster with Surge Protection offers another solid choice. Not only does it provide surge protection, but it also boosts voltage, enhancing the RV’s electrical system performance. This dual functionality makes it a practical investment for any serious RV owner.
A surge protector is not just a luxury; it is a necessary investment. Ignoring this need can lead to costly repairs after unexpected electrical issues. Imagine the regret of losing your entire system to a freak lightning storm because protection was overlooked.
In addition, many surge protectors come with a connected equipment warranty, providing extra assurance. This warranty offers coverage for devices connected to the surge protector, adding a layer of security to the overall protection strategy.
In short, whether opting for a portable or hardwired model, prioritizing surge protection is a wise decision for any RV enthusiast. Ensure safety and preserve valuable equipment on every journey.
