An RV surge protector is a device that connects between your RV and the power source. It checks the incoming electricity and blocks harmful surges. These surges can come from lightning, faulty wiring, or unstable campground power.

Key Benefits:

• Stops power spikes before they reach your RV
• Protects expensive electronics and appliances
• Alerts you to wiring problems

• Helps prevent electrical fires

How to Choose the Best RV Surge Protector 30 Amp/50 Amp

Before buying, think about your RV’s power needs and how you travel.

1. Know Your Amp Rating

• 30-amp RVs use one hot wire and are common in smaller rigs.
• 50-amp RVs use two hot wires and are found in larger motorhomes.

2. Portable vs. Hardwired

• Portable: Easy to plug in and move. Great for travelers.
• Hardwired: Installed inside your RV. Offers theft protection and convenience.

3. Look for EMS Features

EMS stands for Electrical Management System. It adds extra protection like:

• Voltage monitoring
• Auto shutoff
