RV circuit breakers help keep your electrical system safe and operational. When too much electricity flows through your RV's electrical system, it is the job of the circuit breaker to stop the flow of that electricity. This may seem frustrating when it happens, but it saves you from melted wires, fire damage, and more.
Circuit breakers prevent your RV's electrical system from becoming overloaded and therefore, causing fire and electric shock. In other words, they act as a failsafe: they interrupt the power in case of an electrical surge. This is the main reason why they trip.
When you use electricity in your RV, the first place the current goes to is the circuit breaker box. Here, it becomes divided into the different circuits that run throughout your rig. In places where only a small amount of electricity is used (for lights, alarm clocks, and other small items), 15-amp circuits are generally used.
AFCI (arc fault circuit interrupter) circuit breakers protect against unintentional electrical discharge in wiring. Once the breaker senses the electrical fault, it shuts off, protecting you from the potential damage from the electrical arc.
