Your electrical panel is the heart of your building power distribution system. For homes and commercial properties across Sonoma County, an outdated or undersized panel creates real problems: tripped breakers, inability to add new equipment or appliances, code compliance issues, insurance complications, and fire risk. Firebrand Electric specializes in panel upgrades that keep your property running safely and efficiently.
Whether you need a simple 200-amp residential panel swap or a complex commercial service entrance upgrade, our licensed electricians handle the entire process — from assessment and PG&E coordination to permitting, installation, and final inspection. We have upgraded hundreds of panels across Santa Rosa, Petaluma, Windsor, Healdsburg, and every corner of Sonoma County.
Common signs your electrical panel needs attention include frequent breaker trips especially when running multiple appliances, flickering lights under load, panels that are warm to the touch, use of Federal Pacific Stab-Lok or Zinsco equipment which have documented failure rates, running out of breaker spaces and relying on tandem breakers or double-taps, panels rated at 100 amps or less in homes with modern electrical demands, and insurance company requirements to replace outdated equipment.
If your Sonoma County home was built before 1990, there is a good chance the original panel was not designed for todays electrical demands. Air conditioning, EV chargers, home offices, hot tubs, solar systems with battery storage, induction cooktops, and electric dryers all add significant load that older panels simply cannot support safely.
Tenant improvements and build-outs in Santa Rosa, Petaluma, and Windsor frequently require panel upgrades or new sub-panels to support the electrical demands of modern commercial spaces. Whether you are converting a retail space to a restaurant, adding server rooms, installing new HVAC systems, or preparing for EV charger installations, we size and install panels that meet your current and future needs.
We also see many commercial properties in downtown Santa Rosa and Petaluma historic districts where original electrical infrastructure dates back decades. These buildings need careful assessment and often require coordinated upgrades with PG&E to increase service entrance capacity. For commercial clients planning build-outs or renovations, we coordinate panel upgrades with the broader project timeline so electrical capacity is in place when new equipment arrives.
Sonoma County homes — especially those built in the 1960s through 1980s in neighborhoods throughout Santa Rosa, Rohnert Park, Sebastopol, and Cotati — commonly have 100-amp or even 60-amp panels that cannot support modern electrical demands. Adding air conditioning, electric vehicle chargers, hot tubs, home offices, or solar systems with battery storage often requires upgrading to a 200-amp or 400-amp panel.
We regularly upgrade panels in homes across Sonoma, Kenwood, Healdsburg, and the surrounding wine country communities where older construction meets modern lifestyle demands. Every residential upgrade includes a full load calculation, permit filing with your local building department, and a final inspection to ensure everything meets current NEC and California electrical code requirements.
Federal Pacific Stab-Lok panels, Zinsco panels, and certain Challenger panels have well-documented failure rates. Independent testing has shown that Federal Pacific breakers fail to trip in up to 25 percent of overload situations — meaning they may not protect your home during the exact scenario they are designed for. If your Sonoma County home or business has one of these panels, replacement is not optional — it is a safety issue. Insurance companies are increasingly requiring panel replacements as a condition of coverage or renewal.
Our process starts with an on-site assessment where we evaluate your existing service, panel condition, current loads, and planned additions. We provide a detailed scope of work and transparent pricing before any work begins.
1. Assessment: We inspect your current panel, measure existing loads, discuss your planned electrical additions, and determine the appropriate panel and service size.
2. PG&E Coordination: If the service entrance capacity is increasing — for example from 100-amp to 200-amp — we coordinate with PG&E for the meter upgrade and temporary disconnect.
3. Permitting: We pull all necessary permits from your local building department.
4. Installation: New panel installation with proper copper busing, correctly rated breakers, torqued connections, and clear circuit labeling. For commercial projects, we schedule the switchover during off-hours or weekends to minimize downtime.
5. Inspection: County electrical inspection to verify code compliance.
6. PG&E Reconnection: Meter reconnection and service activation.
We install panels from trusted manufacturers including Square D, Eaton, and Siemens. All connections are torqued to specification, and every circuit is labeled clearly so you — and any future electrician — can quickly identify what each breaker controls.
California electrical code requires arc-fault circuit interrupter (AFCI) protection on many circuits during panel replacements. GFCI protection is required in kitchens, bathrooms, garages, outdoors, and other specific locations. Our electricians understand current code requirements and ensure your upgrade brings your system into compliance without unnecessary additions that inflate the cost. We explain which upgrades are code-required versus optional so you can make informed decisions.
A panel upgrade is often the ideal time to address other electrical needs. Many of our Sonoma County customers combine their panel upgrade with EV charger installation, lighting upgrades, dedicated circuits for new appliances, solar preparation, whole-house surge protection, and generator transfer switch installation. Bundling this work saves on permitting costs, reduces the number of times PG&E needs to disconnect service, and minimizes overall disruption.
Firebrand Electric provides panel upgrades throughout Santa Rosa, Petaluma, Windsor, Healdsburg, Sebastopol, Rohnert Park, Cotati, Sonoma, Kenwood, Forestville, Cloverdale, and the greater Sonoma County area. CA License #1063440.

A standard 200-amp panel upgrade in Sonoma County typically costs between $2,500 and $5,000 depending on your home age, existing wiring condition, and whether PG&E service entrance work is required. If the meter base and service entrance cable need replacement to increase from 100-amp to 200-amp service, the cost is at the higher end. We provide detailed written estimates after an on-site assessment.
Most residential panel upgrades are completed in one day. You will be without power for 4 to 8 hours during the swap. If the project involves a service entrance upgrade requiring PG&E coordination, the timeline may extend to include a separate PG&E visit for the meter reconnection, but we schedule this to minimize your inconvenience.
Not necessarily. If your existing wiring is in good condition and properly sized for the circuits it serves, it can remain. The panel upgrade itself does not require rewiring the entire house. However, if we find unsafe conditions during the assessment — such as aluminum wiring connections, damaged insulation, or overloaded circuits — we will recommend addressing those issues for safety.
Yes. Independent testing has consistently shown that Federal Pacific Stab-Lok breakers have a significantly higher failure rate than other brands. The breakers may not trip during overloads or short circuits, which means the protection you think you have may not actually work. Insurance companies and home inspectors routinely flag these panels. We strongly recommend replacement if you have a Federal Pacific panel in your Sonoma County home.
It depends on your current panel capacity and condition. Homes with 200-amp panels in good condition can usually accommodate a solar system without a panel upgrade. Homes with 100-amp panels or panels that are nearly full may need an upgrade to safely add the solar inverter connection. We assess this as part of any solar installation evaluation.
Yes, though 400-amp service is less common in residential applications. It requires a larger meter base, heavier service entrance cable, and PG&E coordination for a 400-amp service drop. This is typically needed for very large homes or properties with multiple buildings, EV chargers, pools, hot tubs, and other high-demand loads. We can evaluate whether 400-amp service is warranted or if load management solutions can keep you within 200-amp capacity.
