The answer to 'panel upgrade keeps tripping' is that the issue is likely caused by an overloaded or faulty electrical panel. Symptoms may include frequent circuit breaker tripping, flickering lights, or appliances not working properly. Common causes include an outdated panel, too many high-draw appliances, loose connections, or a faulty breaker.
If your panel is outdated or you've added new high-draw appliances, it may be time to upgrade to a larger panel with more capacity. This is best done by a licensed electrician, as it requires safely disconnecting the power, upgrading the panel, and ensuring proper wiring. For minor issues like a loose connection or faulty breaker, a DIY repair may be possible, but it's important to take proper safety precautions. If you're not comfortable working with electricity, it's best to call in a professional electrician to diagnose and resolve the problem.
