A home from 1980 was wired for a different era, using NM-B Romex for standard lighting and outlet circuits. The original 100-amp service panel was sized for far fewer appliances than a modern home uses. Today's high-draw devices like air fryers, instant pots, and multiple computers can overload those older circuits, causing voltage drop that manifests as dimming lights. Upgrading the panel and adding dedicated circuits is often necessary to meet 2026 electrical demands safely.

Your Federal Pacific panel is a known safety hazard with a high failure rate and should be replaced regardless of new loads. A 100-amp service from 1980 is insufficient for a Level 2 EV charger or a new heat pump. Adding either would likely overload the system, creating a serious fire risk. A full service upgrade to 200 amps is the required first step, which allows for a new, code-compliant panel and the dedicated circuits these high-capacity appliances need.

Flickering lights often point to a loose connection in your home's wiring or at the service entrance, not necessarily a utility issue. While PG&E's grid and our low lightning risk mean major external surges are rare, micro-surges and brownouts can still occur. A whole-house surge protector installed at your main panel is the most effective defense for sensitive electronics. It's also wise to have an electrician check your panel's bus bars and neutral connections for the cause of the flicker.

For summer peaks, ensure your air conditioning circuit is dedicated and in good condition to reduce strain. Consider a managed generator inlet for essential circuits during extended outages from ice or heat. Installing a whole-house surge protector is critical, as brownouts can be followed by damaging voltage spikes when power restores. These proactive steps, combined with a professional load calculation of your current panel, significantly improve resilience for our climate's extremes.

Overhead mast service is common here. The primary vulnerabilities are at the weatherhead and the mast itself. Check for any sagging or damaged service cables, which are PG&E's responsibility up to the weatherhead. Ensure the mast is securely anchored; high winds in the hills can strain it. From the weatherhead in, all wiring and connections are homeowner responsibility. Any corrosion or loose lugs in the meter base or service panel can lead to intermittent power or heat buildup.

The rolling terrain can impact grounding. Rocky or variable soil conditions may compromise your grounding electrode system, leading to potential voltage irregularities or that noticeable hum. Proper grounding is non-negotiable for safety and equipment protection. Additionally, heavy tree canopy in these areas can cause interference or damage to overhead service drops during storms. An inspection should verify your ground rods meet NEC 2023 depth requirements and that masthead connections are secure.

For an emergency like a burning smell, our dispatch prioritizes immediate response. From a start point near Vine Hill Elementary School, we use I-680 for direct access, typically arriving within 8 to 12 minutes. Your first action should be to shut off the main breaker at the service panel if it's safe to do so. We'll diagnose the fault, which often involves overheating connections or a failing breaker, and secure your home to prevent a fire.

Any service panel upgrade requires a permit from the Contra Costa County Building Inspection Department and must be installed to NEC 2023 standards. As a C-10 licensed contractor, I handle the permit application, scheduling of inspections, and PG&E coordination for the meter disconnect and reconnect. The county inspector will verify proper sizing, AFCI/GFCI protection, and grounding. Attempting this without a permit and licensed professional risks fines, invalidated insurance, and serious safety hazards.
