The answer to 'what is panel upgrade' is a process of replacing an older, outdated electrical service panel with a new, more modern and higher capacity panel. This is often necessary when a home's electrical needs have outgrown the existing panel, or when the panel has become unsafe or unreliable due to age or damage.
A panel upgrade typically involves installing a new service panel, usually with a higher amperage rating to handle the increased electrical demands of a modern home. This may include adding more circuit breakers, upgrading the main breaker, and ensuring the panel meets current electrical codes and safety standards. A panel upgrade can also improve the overall efficiency and reliability of a home's electrical system, reducing the risk of power outages, electrical fires, and other safety hazards.
