The answer to 'why is my circuit breaker flickering lights' is that a flickering circuit breaker is often a sign of an overloaded or faulty electrical circuit. This can be caused by too many devices or appliances drawing power from the same circuit, a short circuit, or a problem with the circuit breaker itself.
Some common symptoms include lights flickering, power surges, or the circuit breaker tripping repeatedly. This could indicate an issue like a loose connection, damaged wiring, or a failing circuit breaker. If the problem persists, it's best to have a professional electrician inspect the circuit and make any necessary repairs.
