Understanding RV Circuit Breaker


As outdoor enthusiasts, RVers take the opportunity to travel, explore, and revel in the beauty that nature has to offer. However, the beauty of the outdoors can also bring challenges to RVers when it comes to their vehicles. One of the most common issues is electrical problems, which can put a halt to your trip if not addressed promptly. That's where the RV circuit breaker comes in. In this guide, we'll help you understand what an RV circuit breaker is, how it works, and how to choose the right one for your RV.


What is an RV circuit breaker?

An RV circuit breaker is an important component of your RV's electrical system that controls the amount of electrical current flowing through each circuit. It is basically a switch that automatically shuts off when too much electrical current is detected to prevent damage to your RV's electrical system and appliances. It works by monitoring the electrical flow and, when it exceeds the specified limit, it stops the current by tripping the breaker.

Types of RV circuit breakers

RV circuit breakers come in two types: thermal and magnetic. Thermal breakers work by heating up a bi-metallic strip, which bends and eventually opens the circuit. On the other hand, magnetic circuit breakers work mainly on the magnetic fields created by the current flowing through the circuit.

Choosing the Right RV Circuit Breaker

When it comes to choosing the right RV circuit breaker, it largely depends on two factors: the capacity of your RV's electrical system and the appliances you're using. It is recommended to use circuit breakers that match the amperage of the appliance or circuit. For instance, appliances like air conditioners may require a higher amperage circuit breaker to handle the load.

Maintaining Your RV Circuit Breakers

Like every RV component, it's important to maintain your RV circuit breakers regularly. Check for any damage or wear and tear to the circuit breaker and its wires. If you notice any issues, replace the circuit breaker immediately. Also, make sure to turn off the circuit breaker before working on it or replacing it.



In conclusion, understanding your RV circuit breaker and how it works is essential for every RVer. It will allow you to troubleshoot and fix electrical issues on the road, making your trip more enjoyable and stress-free. Remember to choose the right circuit breaker for your electrical system, maintain it properly, and replace it when necessary.
