RV Surge Protector Buying Guide

Know Your Amperage

RVs typically use either 30 or 50 amp service. You need to match your surge protector to your RV's electrical system:

• 30 Amp RVs: Smaller trailers, Class B and Class C motorhomes
• 50 Amp RVs: Larger fifth wheels, Class A motorhomes with multiple AC units

Portable vs. Hardwired

Portable: Connects between the power pedestal and your RV's power cord. Easy to use, can take with you if you change RVs.

Hardwired: Permanently installed inside your RV. Offers protection without having to set up every time you park. No risk of it being stolen.

Protection Level

Basic Surge Protection: Protects against power surges and may indicate some electrical issues.

Advanced EMS: Full protection systems that monitor for all electrical issues and automatically disconnect when dangerous conditions exist.

• Joule Rating: Higher is better (2,000+ for 30 amp, 3,000+ for 50 amp)
• Weather Resistance: Important for outdoor exposure
• Warranty: Lifetime warranties offer the best long-term value
• Display Type: Digital displays provide more detailed information

Costs of Electrical Damage

• Air conditioner control boards ($300-500)
• Refrigerator circuit boards ($500-800)
• Microwave electronics ($200-400)

Things to Consider

• Typical camping locations (established campgrounds vs. mom & pop)
