What's different about electrical panel upgrade in Modesto
The Modesto Irrigation District, which provides electricity in the city, schedules the disconnect and reconnect and reviews solar interconnection. A load calculation decides the right size. Permits come from the City of Modesto's building division, and work requires a CSLB-licensed contractor.
Older homes may have original wiring and small panels, and many postwar homes have Zinsco or Federal Pacific panels. Rooftop solar and EV chargers often push older panels past their limits. Valley summers keep AC running for months, so outdoor disconnects and condenser circuits wear out faster than in milder climates.
