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 main service panel upgrades, subpanel installations, and panel replacements.
A main service panel upgrade involves increasing the amperage capacity of your home's main electrical service, usually from 100 amps to 200 amps. This is often necessary when adding major new electrical loads like an electric vehicle charger, central air conditioning, or a large home addition. Subpanel installations add additional electrical capacity to specific areas of the home, like a garage or workshop. And a full panel replacement may be required if your existing panel is outdated, damaged, or no longer meets electrical code.
