Serving San Diego County and the Inland Empire — panel upgrades permitted, inspected, and done right.
Two panel brands with documented safety failures that affect thousands of Temecula-area homes built before 1990.
FPE Stab-Lok breakers fail to trip during overloads at a documented rate of 25–65%. The Consumer Product Safety Commission investigated these panels in the 1980s. Many insurance carriers now refuse to insure homes with FPE panels.
What to do: Replace the entire panel — not just the breakers. The bus bar design is the underlying flaw.
Zinsco breakers are known to fuse to the bus bar, making them impossible to manually trip. They can fail to interrupt fault current, allowing sustained arcing inside the panel. Like FPE, the entire panel should be replaced.
What to do: Full panel replacement with a modern Square D, Eaton, or Siemens unit.
We assess your existing service, determine the correct panel size, and pull the city permit before any work begins.
We coordinate with Southern California Edison for the power shutoff window — typically a 4-hour morning window.
Panel installed, labeled, and tested. City inspector signs off. Power restored same day in most cases.
Most residential panel upgrades fall between $3,500 and $6,500. Larger scope projects — including service upgrades with new meter sockets, mast replacements, or coordination with SCE / SDG&E — can run higher. We provide written flat-rate quotes before any work begins.
Rebates & Incentives Available
SCE customers may qualify for up to $4,200 through the Charge Ready Home program. Federal tax credits of up to 30% may also apply.
See all available rebates →A 100A to 200A electrical panel upgrade in Temecula typically costs $3,500–$6,500+ installed, permitted, and inspected. Price varies based on SCE / SDG&E coordination requirements, meter socket condition, and local permit fees.
Most residential panel upgrades are completed in a single day. We coordinate the SCE / SDG&E power shutoff in advance and schedule the inspection so power is restored the same day.
Yes. Federal Pacific Stab-Lok and Zinsco panels have documented failure rates where breakers don't trip during overloads, creating a fire hazard. Insurance companies increasingly refuse to cover homes with these panels. Replacement is strongly recommended.
Not always. If you have a 200A panel with available breaker space, you likely don't need an upgrade. If you have 100A service or the panel is full, an upgrade is typically required. We assess this during your free quote visit.
