The answer to 'generator circuit overload' is that a generator circuit overload can be caused by too much electrical load being placed on the generator, which can lead to the generator shutting down or tripping a circuit breaker. Symptoms of a generator circuit overload include the generator slowing down, dimming lights, or tripping a circuit breaker. To solve this, you should reduce the electrical load on the generator by turning off or unplugging some of the devices or appliances being powered by it.
If the overload persists, it may be due to a problem with the generator itself, such as a faulty alternator or voltage regulator. In this case, it's best to call a professional electrician to diagnose and repair the generator.
