Preparation focuses on safety and core function. For summer peaks, ensure your panel and breakers are in good condition to prevent overheating. For winter, a licensed electrician can install a manual transfer switch for a portable generator, allowing you to safely back up essential circuits. Avoid unsafe practices like 'backfeeding' power through an outlet. Whole-house surge protection also guards against voltage spikes when grid power is restored.

It's highly likely. Homes in Rollingwood from the early 1960s were wired with cloth-jacketed copper for a different era of electricity use. That 65-year-old insulation becomes brittle and can't safely handle the simultaneous demands of modern appliances like central air, computers, and kitchen gadgets. This creates overloaded circuits and voltage drop, which manifests as dimming lights and is a significant fire risk that requires evaluation.

While PG&E grid-switching events are the primary source of minor surges in our area, your sensitive electronics are telling you your home lacks proper protection. These small, repeated surges degrade circuitry over time. The solution isn't just a power strip; it's installing a whole-house surge protective device at your main panel. This device, required by the current electrical code, clamps these grid disturbances before they reach your expensive electronics.

Yes, terrain directly impacts grounding. The rocky, hilly soil common on these coastal slopes often has high resistance, making it difficult to establish a proper ground for your electrical system. A poor ground can lead to erratic breaker trips, equipment damage, and is a safety hazard. We test ground resistance with specialized meters and may need to drive additional grounding rods or use chemical enhancements to achieve a code-compliant, low-resistance ground path.

With a 100-amp service from 1961, adding a Level 2 EV charger is not feasible and would be unsafe without a full service upgrade. The math is straightforward: a charger alone can draw 40-50 amps, nearly half your home's total capacity. Furthermore, we must check for a Federal Pacific panel, a known fire hazard common in homes of that era. A modern 200-amp service is the required foundation for an EV charger or a new heat pump system.

Overhead service masts, standard for 1960s Rollingwood homes, have specific failure points. The mast itself can corrode or be damaged by tree limbs, and the service entrance cables connecting to it degrade over 65 years. We inspect for weathering, proper mast head height, and secure connections at the weatherhead. During a service upgrade to 200 amps, we replace the entire mast assembly with new, rated components to handle the increased capacity safely.

For a no-power, burning smell emergency, we treat it as a priority one dispatch. From our location near the park, we can typically be on-site in your Rollingwood neighborhood within 8 to 12 minutes using I-280 for the fastest route. Your first action should be to call 911 if you see smoke or flames, then call us. We'll secure the service and locate the fault immediately upon arrival.

A panel upgrade always requires a permit from the San Bruno Building Division. As your electrician, we handle the application, detailed plans, and scheduling of inspections. The 2025 California Electrical Code, which adopts the 2023 NEC, is strict on safety—mandating AFCI breakers for most circuits and specific surge protection rules. Our work is performed under a California CSLB license, ensuring full compliance so your upgrade is safe, legal, and insurable.
