Overloading the generator happens sometimes, especially if your generator doesn’t have a built-in voltmeter. In that case, depending on the construction of your generator, the engine will either automatically shut off or a circuit breaker will trip. If your generator has a built-in circuit breaker, you’ll likely need to reset the breakers using switches on your generator’s outlet panel. If specific outlets don’t have a reset button and there is no main breaker switch, you’ll need to turn the generator’s engine off to reset the system.
