Frequently Asked Questions About Electrical in Cupertino

How much does a panel upgrade cost in Cupertino?+
A 200-amp panel upgrade in the Cupertino area costs $1,800–$4,500 depending on complexity. A straightforward panel swap averages $2,500–$3,500. If your meter base also needs replacement or the utility requires a riser upgrade, expect $3,500–$4,500.
Do I need a panel upgrade for an EV charger?+
Most Level 2 EV chargers require a dedicated 50-amp circuit. If your panel is 100 amps or less, you'll likely need an upgrade to 200 amps. Many Cupertino homes built before 2000 have undersized panels. We can assess your capacity and handle the full upgrade plus charger installation.
How much does EV charger installation cost?+
EV charger installation in Cupertino costs $500–$2,500 for labor, depending on the distance from your panel to the charger location and whether a panel upgrade is needed. A simple installation with the panel in the garage averages $500–$800.
Do I need a panel upgrade for an EV charger?+
If your home has a 200-amp panel with available capacity, usually not. However, many Cupertino homes have 100-amp panels that can't safely support a 50-amp EV circuit on top of existing loads. We assess your panel before quoting.
How much does it cost to rewire a house in Cupertino?+
Whole-house rewiring in Cupertino costs $8,000–$25,000 depending on home size, accessibility, and whether walls need to be opened. A typical 1,500 sq ft home averages $10,000–$15,000. Homes with easy attic/crawlspace access cost less than those requiring extensive wall work.
How long does rewiring take?+
A full rewire takes 5–10 days for an average Cupertino home. You can typically remain in the home during the work, though power to certain areas will be off at times. Drywall patching and painting after the electrical work adds 1–3 days.
