The answer to 'generator circuit overload' is that it is caused by drawing too much electrical load from the generator, which can lead to the circuit breaker tripping or the generator overheating. Common symptoms include flickering lights, appliances not working properly, or the generator shutting down unexpectedly. To solve this, you'll need to reduce the electrical load on the generator by turning off or unplugging non-essential devices and appliances.
If the overload persists, you may need to upgrade to a larger generator that can handle the power demand. In some cases, a faulty generator or wiring issue could also be the cause, so it's best to have a professional electrician inspect the system if the problem continues.
