The answer to 'why is my panel upgrade' is that your electrical panel may need to be upgraded for several common reasons, such as an outdated or insufficient capacity, safety issues, or the need to accommodate new electrical demands in your home. Symptoms of a needed panel upgrade include frequently tripping breakers, burning or discolored outlets, and difficulty adding new circuits or appliances.
The solution is to have a licensed electrician assess your panel and electrical system and determine if an upgrade is necessary. This may involve replacing the entire panel with a larger, more modern unit, adding sub-panels, or upgrading the main service to your home. While some basic electrical work can be done DIY, a panel upgrade should always be handled by a professional to ensure it's done safely and up to code.
