The Best RV Surge Protectors And Electrical Management Systems (2021)

RV surge protectors are a necessary accessory to protect your electric system, and internal appliances.

Many campers will tell you that surge protectors are not necessary, but it only takes one bad connection and you’ll quickly be out thousands of dollars in equipment.

Surge protectors are inexpensive, and will give you peace of mind while camping. In this article, we’ll tell you what to look for, and how to find the best surge protector for your camper or trailer.

Why Get an RV Surge Protector?

A surge protector monitors and protects your RV’s power supply. It finds defects and levels electricity usage, protecting the RV and its equipment.

You can lose your power supply with one small bad connection. Whether you use your RV every day, seasonally, or once a year, having an RV in your toolkit is a must. 

Your RV will need protection in the following scenarios:

  • Power surges
  • Voltage drops
  • Lightening strikes
  • Poor wiring

Surge protectors prevent voltage spikes.

What Is An Electrical Management System?

Electrical management systems are similar to surge protectors, but they protect against every type of bad power connection.

They will also give you amperage readings, high and low frequency protection, and protect against faulty grounds.

Electrical management systems are more expensive than a standard surge protector. But they offer the best protection for your camper!

What To Look For In An RV Surge Protector

Amp Rating

This indicates the amount of power you’ll use. You want one that’s appropriate for your operation. Otherwise, you increase the change of overheating, fire, and electrical problems.

If you have a 30 amp RV, you should use a 30A surge protector. If you have a 50 amp RV, you should use a 50A protector; simple as that!

Installation

Simple surge protectors plug in-between the campground power pedestal and your RV power cord.

Electrical management systems are hardwired into your camper. These require more installation, but you won’t have to worry about leaving them behind!

Weight

Choose a lightweight unit. You don’t want to add too much of a load to your ride. Plus, if you have an outdoor unit, you want to avoid breaking your back during the physical transport.

Display

The best surge protectors have indicator lights that will show you additional information such as:

  • Open Neutral
  • Open Ground
  • Reverse Polarity
  • Open Circuit/No Power
  • Surge Protection Status
  • Overheating Plug/Receptacle
