Underground service laterals, common in Foster City, mean your main electrical feed comes from a PG&E transformer via a buried conduit. Upgrading your service or adding a sub-panel requires coordination with the utility to ensure the existing lateral can handle the increased load. The work involves pulling new conductors from the property line to your new meter main and panel, which must be permitted and inspected by the Foster City Community Development Department.

Foster City's flat coastal plain and soil conditions can impact grounding electrode performance. Damp, saline soil near the lagoon is generally good for conductivity, but it can also accelerate corrosion on metal grounding rods and connections. We verify that the grounding electrode system is intact, has low resistance, and that all connections are clean and tight. This is a critical part of ensuring your safety systems function properly.

All panel replacements require a permit from the Foster City Community Development Department. As of 2026, all work must comply with the California Electrical Code, which is based on the NEC 2023. This includes requirements for AFCI and GFCI protection, specific working clearances around the panel, and proper labeling. We handle the permit process and ensure the installation passes inspection, providing you with documentation for your records and future home sales.

For summer AC peaks, ensure your cooling system is on a dedicated, properly sized circuit and consider a whole-house surge protector to guard against voltage sags. For extended outages during rare winter cold snaps, a permanently installed generator with an automatic transfer switch is the safest, code-compliant solution. Portable generators must be used with extreme caution and never connected directly to your home's wiring without a proper transfer switch to avoid back-feeding the grid.

For an emergency like a burning smell, we prioritize immediate dispatch. From our shop near Leo J. Ryan Park, we can typically be on site in Foster City within 5-8 minutes, using US-101 for quick access to the Central neighborhood. Our first priority is making the situation safe by identifying the source—often a failing breaker or loose connection—and securing your power.

Flickering lights often point to a loose connection in your home's wiring, typically at an outlet, switch, or within the main panel. While PG&E maintains a reliable grid here with low surge risk from lightning, minor grid fluctuations can occur. However, your smart home electronics and appliances are most vulnerable to the voltage variations caused by internal faults. A diagnosis will pinpoint if the issue is on the utility side or, more commonly, within your property.

Yes, a Federal Pacific panel is a known safety hazard and should be replaced immediately. These panels have a high failure rate and may not trip during an overload, creating a serious fire risk. Furthermore, a 100-amp service from 1976 cannot safely support the simultaneous load of a heat pump and a Level 2 EV charger. A full service upgrade to 200 amps and a new, code-compliant panel is the necessary first step for both safety and capacity.

Your 50-year-old NM-B (Romex) wiring from 1976 is likely safe if undisturbed, but it was installed for a different era. Modern 2026 homes demand far more power for computers, large-screen TVs, and kitchen gadgets. This original 100-amp service and circuits can become overloaded, causing breakers to trip and creating excessive heat at connections. An evaluation can determine if you need new circuits to handle today's loads safely.
