A whole-house surge protector installs at your main electrical panel and clamps voltage spikes from lightning, utility switching, and PSPS reconnections before they reach your electronics and appliances. NorCal homeowners are especially vulnerable to surges during PG&E PSPS events when power is restored, as the initial reconnection can produce significant voltage spikes. Surge protectors rated for Type 1 or Type 2 application divert excess voltage to the grounding system, protecting everything plugged into your home's outlets. We install Eaton, Siemens, and Leviton panel-mount SPDs rated for 50,000-100,000A surge capacity.

NorCal's PSPS events create unique surge risks during power restoration. Summer thunderstorms in the Sierra foothills also produce lightning strikes that cause utility surges reaching valley homes through the grid.

Berkeley is located in Alameda County (East Bay). Iconic university city with Craftsman bungalows, brown-shingle homes, and modern condos. The local utility provider is PG&E.

California Building Code

NEC 2020 (Article 230.67) requires Type 1 or Type 2 surge protection on all new dwelling unit service equipment. California adopted this requirement in the 2022 California Electrical Code. SPD lead lengths should be as short as possible (ideally under 6 inches) for optimal performance.

Project Timeline

Panel Assessment

15 min

Inspect the panel for available breaker space, verify the grounding system is adequate, and select the correct SPD model for the panel brand. Check the main bonding jumper and grounding electrode.

SPD Installation

30-45 min

Install the dedicated 2-pole breaker, mount the SPD as close to the main breaker as possible (short lead lengths improve performance), and connect the SPD leads to the breaker and neutral/ground bus.

Testing & Verification

10-15 min

Energize the SPD, verify the indicator light shows active protection, test the panel voltage, and confirm grounding integrity. Demonstrate the status indicator to the homeowner.

Whole-House Surge Protector in Berkeley — FAQ

How much does a whole-house surge protector cost?+

A professional whole-house surge protector installation in NorCal costs $300-$600 including the device, breaker, and labor. This is a small investment compared to the $5,000-$20,000+ in electronics and appliances it protects.

Do I still need power strip surge protectors?+

Yes. Whole-house SPDs handle large external surges (lightning, utility). Point-of-use power strip protectors catch smaller, internally generated surges from appliance motors. A layered approach (panel + power strip) provides the best protection.

How long do surge protectors last?+

Whole-house SPDs last 5-10 years depending on how many surges they absorb. Most have LED indicators that change color when the device is depleted. We recommend checking the indicator annually.

Why are PSPS reconnections a surge risk?+

When PG&E restores power after a PSPS event, the initial energization can produce voltage spikes as transformers re-energize. These spikes can damage unprotected electronics. A whole-house SPD clamps these surges before they reach your devices.
