The answer to 'electrical panel dimming lights' is that dimming lights can be caused by a variety of issues with the electrical panel, such as a loose or faulty connection, a circuit overload, or a problem with the panel's wiring. Symptoms may include flickering or dimming lights, especially when other high-wattage appliances are in use.
To troubleshoot this issue, start by checking the circuit breakers in the electrical panel. If a breaker is tripped or the panel is making unusual noises, that could be the cause. You can also try resetting the breakers and see if that resolves the problem. However, if the issue persists or you're not comfortable working with the electrical panel, it's best to call a licensed electrician to diagnose and fix the problem safely.
