The answer to 'why is my circuit breaker not working' is that there are several common causes, including an overloaded circuit, a short circuit, or a faulty breaker. Symptoms may include flickering lights, appliances not working, or the breaker tripping repeatedly. Solutions can range from resetting the breaker to replacing a damaged one.
If the breaker is tripping frequently or you're unsure of the cause, it's best to call an electrician. They can diagnose the issue and make any necessary repairs or replacements to restore your electrical system safely. Trying to fix a complex problem yourself can be dangerous, so it's important to know when to call in a professional.
