Flickering lights often point to a loose connection in your home's wiring, such as at a switch, outlet, or within the main panel. While PG&E provides generally stable power in this area with low lightning-related surge risk, minor grid fluctuations can occur. However, modern electronics are sensitive to even small voltage variations. A whole-house surge protector installed at your panel and a professional evaluation of your connections will protect your devices and resolve the flickering.

Summer air conditioning peaks strain the grid and can lead to brownouts. A professionally installed automatic standby generator, wired through a transfer switch, will keep essential circuits online. For winter, ensuring your heating system's electrical components are serviced is key. In both scenarios, a whole-house surge protector is critical; brownouts and power restoration often create damaging voltage spikes that can harm appliances and electronics, even with our area's low lightning frequency.

Homes from 1971 were wired with NM-B Romex cable, which was adequate for the era. The challenge is that modern 2026 appliances like inverter-driven AC units and refrigerators have much higher instantaneous startup loads. Your original 100-amp service panel and branch circuits are likely operating at capacity, causing voltage drop—manifesting as dimming lights—when a large motor kicks in. Upgrading to a 200-amp panel with new dedicated circuits is the standard solution to safely meet today's electrical demands.

For an emergency like a burning smell, which indicates a potential fire hazard, we dispatch immediately. From our starting point near the Hillsborough Town Hall, we take I-280 for direct access, typically arriving within 5 to 8 minutes. Our first priority is ensuring your safety by disconnecting power at the main breaker if it's safe to do so, then diagnosing the fault—often a failed breaker or overheated connection—to prevent further damage.

No, it is not safe. Federal Pacific panels are a known fire hazard due to breakers that can fail to trip during an overload. Furthermore, a 100-amp service from 1971 lacks the capacity for a Level 2 EV charger or a modern heat pump. Both require dedicated, high-amperage circuits. The necessary first step is a full service upgrade to a minimum of 200 amps with a new, UL-listed panel and AFCI/GFCI breakers to provide both the safety and the power your new equipment needs.

An underground service lateral, common in Hillsborough, offers reliability and aesthetics but requires specific considerations for upgrades. The conduit from the PG&E transformer to your meter must be sized correctly for new, larger cables if you increase your service amperage. We coordinate the trenching and conduit work with the Hillsborough Building and Planning Department for permits. While the meter and main panel location are fixed, we plan the new panel installation and grounding around this existing underground entry point.

Yes, the heavy tree canopy and rolling hillside terrain common in Lower North Hillsborough can impact electrical health. Overhead service lines, if present, are vulnerable to falling limbs during storms. More subtly, rocky or variable soil conditions can compromise the grounding electrode system, which is essential for safety and surge dissipation. We test ground resistance to ensure it meets NEC standards, and recommend tree trimming to maintain clearance from any utility lines entering your property.

All panel replacements require a permit from the Hillsborough Building and Planning Department and must comply with the 2023 California Electrical Code, based on NEC 2023. As a CSLB-licensed master electrician, I handle the permit application, scheduling of inspections, and ensure the installation meets all current safety standards for AFCI protection, grounding, and load calculations. This process not only ensures safety but also provides a legal record of the upgrade for home insurance and future sales.
