The answer to 'types of panel upgrade' is that there are several common types of electrical panel upgrades homeowners may need to consider. The most common are upgrading to a larger main service panel, converting to a modern circuit breaker panel, and replacing an outdated fuse box with a breaker panel.
Upgrading to a larger main service panel is often necessary when a home's electrical needs have grown beyond the capacity of the existing panel, such as when adding major new appliances or converting to an electric heating system. This involves installing a new, higher-capacity main service panel to handle the increased electrical load.
