Electrical Panel Upgrades in Cupertino, CA

Usually yes. Most 1960s and 70s Cupertino ranch homes were built with 100-amp service that is already close to full once you add modern HVAC and a home office. Before we quote an upgrade we run a load calculation to confirm it, because sometimes a load-management device gets you charging without a full panel swap. If you are also planning a heat pump or induction range, 200 amps is usually the smarter call.

Yes, and this is exactly the kind of home where it matters. The Eichlers in Rancho Rinconada have post-and-beam roofs, radiant slab heat, and no attic, so there is nowhere to hide a wire run overhead. We plan the new service and any added circuits around the slab and exterior walls instead of cutting into those ceilings. It is the way these specific homes have to be wired.

Both, in their own roles. Cupertino is PG&E territory, so PG&E handles the service disconnect and reconnect at the meter, while the electrical permit and inspection run through the City of Cupertino Building Division. We pull the permit, schedule the PG&E window, and attend the inspection, so you are not chasing two agencies yourself.

The outage window depends on the approved work, PG&E scheduling and the required Cupertino inspections. Confirm the disconnect and reconnect arrangements before the installation date, including what happens if work or inspection takes longer than planned.

Often not. The newer townhome developments along Stevens Creek tend to have modern panels with some spare capacity, so the work is usually adding a dedicated charging circuit rather than replacing the panel. We confirm with a load calculation, and where an HOA or shared garage is involved we work out the metering and routing before any wire is run.

Identify the panel rating, breaker layout and branch wiring at the property. A limited number of circuits can justify assessing additional circuits, but it does not by itself establish the need for a 200-amp service or a full rewire. Review the actual loads and proposed appliances before choosing the scope.

The schedule includes city permit review, any PG&E service approval, equipment availability and the inspection/reconnect arrangements. Confirm whether the project qualifies for Cupertino's Instant Permit path, then obtain the utility schedule before choosing an installation date.
