The answer to 'why is my electrical panel circuit overload' is that the circuit is drawing more electrical current than it is designed to handle. This can happen for several common reasons, such as a short circuit, too many high-wattage devices connected to the circuit, or a problem with the circuit breaker itself.
Symptoms of an overloaded circuit can include flickering lights, outlets that don't work, or the circuit breaker tripping frequently. If you're experiencing these issues, it's important to address the problem quickly to prevent potential fire hazards or damage to your electrical system. In some cases, you may be able to resolve the issue yourself by reducing the load on the circuit or resetting the breaker. However, if the problem persists or you're unsure of the cause, it's best to call a licensed electrician to diagnose and fix the issue.
