We Know Sunnyvale's Electrical Challenges

We’ve been handling electrical panel replacements throughout Sunnyvale for years. We understand the unique challenges of homes built during Silicon Valley’s rapid growth periods.

How long does electrical panel replacement take in Sunnyvale?

Most electrical panel replacements in Sunnyvale take 4-8 hours to complete, usually finished in one day. The timeline depends on your home’s specific electrical setup and whether we need to upgrade your meter base or add new circuits. We coordinate the power shutdown with your utility company to minimize disruption. Simple panel swaps are faster, while homes needing electrical service upgrades or extensive rewiring take longer.

Yes, electrical panel replacement requires permits from the City of Sunnyvale. We handle the permit application process for you, including submitting the necessary documentation and scheduling required inspections. The permit ensures your new panel meets current electrical codes and safety standards. Most electrical panel upgrades also require a final inspection before your utility company will restore power. We coordinate with both the city and your utility company to make sure everything is properly approved and inspected.
Electrical panel replacement costs in Sunnyvale typically range from $1,500 to $4,000, depending on the panel size, your home’s electrical setup, and whether additional work is needed. Basic panel swaps cost less, while homes needing service upgrades or meter base replacement cost more. Factors affecting price include the amperage of your new panel, permit fees, inspection requirements, and any necessary electrical code updates. We provide detailed written estimates that break down all costs so you know exactly what you’re paying for.
Replace your electrical panel if it’s over 25 years old, frequently trips breakers, shows signs of corrosion or burning, or can’t handle your electrical load. Many Sunnyvale homes built in the 1970s and 1980s have panels that struggle with modern electrical demands. If you’re adding major appliances, electric vehicle charging, or planning home additions, you likely need a panel upgrade. Insurance companies sometimes require panel replacement for older homes. Any burning smells, sparking, or warm panels indicate immediate replacement needs for safety reasons.
Most Sunnyvale homes need 200-amp electrical panels to handle modern electrical loads adequately. Smaller homes with basic electrical needs might work with 150-amp panels, while larger homes or those with electric vehicle charging, pools, or extensive smart home systems may need larger capacity. We calculate your electrical load based on your home’s size, appliances, and planned electrical usage. The right panel size ensures you have enough electrical capacity for current needs plus room for future additions without overloading your system.
No, electrical panel replacement in Sunnyvale requires a licensed electrician and proper permits. This work involves high-voltage electrical connections that can be deadly if handled incorrectly. California law requires licensed professionals for electrical panel work, and insurance companies won’t cover damage from unpermitted electrical work. DIY electrical panel work also violates local building codes and creates serious safety hazards. Professional installation ensures your new panel is safe, code-compliant, and properly connected to your home’s electrical system and utility service.
