The answer to 'how does panel upgrade work' is that a panel upgrade involves replacing an old, outdated electrical service panel with a new, larger capacity panel. This is done to accommodate increased electrical demands in a home, such as adding new appliances, HVAC systems, or home automation. The process typically involves shutting off power to the home, removing the old panel, installing the new panel, and reconnecting all the electrical circuits to the new panel.
A panel upgrade is an important electrical project that should be done by a licensed electrician. They will ensure the new panel is properly sized and installed to safely handle the home's electrical needs. The electrician will also check the condition of the home's wiring and make any necessary updates or repairs during the upgrade process.
