200A Main Panel Upgrades in San Jacinto & Hemet: When Do You Need One?

Oct 5
2 min read

Homeowners in San Jacinto, Hemet, and nearby Riverside County communities often ask whether they need to upgrade from a 100-amp electrical service to 200 amps before adding an EV charger, battery backup, solar, an ADU, new HVAC equipment, a spa, or other major electrical loads. The answer depends on the property and the calculated electrical load.


When a 200A Main Panel Upgrade May Make Sense


A larger service may be appropriate when the existing electrical system does not have enough calculated capacity, when the panel is outdated or physically full, when new equipment adds substantial demand, or when utility and permit requirements make an upgrade necessary. In other cases, the existing service may still support the project after a proper load evaluation.


EV Chargers and Panel Capacity


A Level 2 EV charger can add a significant continuous load. Before installation, the service and panel should be evaluated for available capacity, breaker space, conductor size, routing, and permit requirements. A panel upgrade is one possible solution, but it should be recommended only after the existing system is reviewed.


Battery Backup, Solar, ADUs and New Loads


Battery, solar, ADU, HVAC, spa, and remodel projects can all change the electrical demand on a property. Planning the service early helps coordinate feeders, subpanels, backup circuits, inverter capacity, and future loads as one electrical system instead of separate projects.
