When it comes to protecting your RV and its electronics, few products are more important than a high-quality surge protector. Monitoring the power coming into your RV and blocking damaging electrical issues is essential. So today, we wanted to look at the Southwire Surge Guard 50 amp surge protector to see if it’s the right fit for you. 

Why Every RVer Should Use a Surge Protector

In the absence of a surge protector, your RV and its contents are at risk of damage. When unstable voltage occurs, it can damage appliances in your RV. Sensitive electronics require a certain amount of power to operate correctly. Motors and wiring often permanently fail when subjected to low and high voltages. Subjecting wiring to voltage spikes can cause a fire, which is never something you want to risk when it comes to your RV.

The Southwire 50 amp Surge Guard analyzes the power pedestal to ensure proper electrical conditions are present before allowing power to the RV. The Surge Guard provides protection against open ground, open neutral, and reverse polarity. It also works to keep your RV safe from a miswired pedestal as well as low or high-voltage fluctuations.  

Our Favorite Features of the Southwire 50 Amp Surge Guard 

There are many products out there that monitor incoming power. Here are a few reasons why we think the Southwire 50 amp Surge Guard is a top pick. 

Easy-to-Read Display

The easy-to-read digital display doesn’t leave you guessing. There’s an LED screen with backlighting so you can access the information you need in any light. The display tells you the amps and voltage draws but will display error alerts when present. Additionally, users can choose to see voltage and frequency readouts.

Lifetime Warranty

Should your Surge Guard 50 amp fail with proper usage, the company will either repair or replace your unit. Surge protectors often come at a high price as they’re a complex device that does an important job, so a lifetime warranty on the surge protector gives you confidence in your purchase. 

Low and High Voltage Protection

Both low and high voltage can be equally damaging to your RV. Some surge protectors only guard against high voltage, but that’s only half the equation, but the Surge Guard 50 amp surge protector will defend you against both. This unit constantly monitors voltage and frequency, indicating potential improper polarity and ground wiring.

While this Surge Guard 50 amp surge protector has a lot going for it, there are, of course, cons with any product. So let’s look at what might become a source of frustration for you should you choose to make this your purchase. 

Pull Handle Can Be Difficult to Use

When leaving the campsite, the last thing you want to do is deal with a demanding teardown process. The pull handle on this surge protector can be difficult to remove from the pedestal. Those who have limited strength in their hands may need assistance with unplugging the unit.
