PANEL UPGRADES
Older Oakland Homes, Modern Electrical Loads
Much of Oakland's housing stock was wired for a fraction of the load a modern household draws. A 100A service that coped in 1965 is now running a heat pump, an induction range, and increasingly a car.
VoltGuard handles the whole upgrade: load calculation, City of Oakland permit, PG&E coordination, the panel change itself, and final inspection sign-off. You get one contractor and one point of contact.
WHAT WE DO
Panel and Service Upgrade Work in Oakland
From a straightforward board swap to a full service upgrade with utility coordination.
100A to 200A upgrades
Full service upgrade including mast, meter, panel and grounding brought up to current code.
Subpanel installation
Added capacity for garages, ADUs, workshops and rear extensions without replacing the main.
Breaker box replacement
Like-for-like replacement where the service size is adequate but the enclosure has failed.
Federal Pacific replacement
Stab-Lok panels have a documented failure-to-trip history. Replacement is strongly advised.
Zinsco replacement
Another known-defective legacy board still common in Oakland properties. Replaced in full.
Meter main combination
Combined meter and main units for properties where the utility connection is also being renewed.
Permit and PG&E coordination
City of Oakland permit filed and the utility disconnect and reconnect scheduled on your behalf.
EV and solar-ready capacity
Panels specified with headroom so a future charger or array does not force a second upgrade.
Load calculation
NEC-compliant calculation establishing the service size your property actually needs.

COMMON QUESTIONS
Frequently Asked Questions
How long does a panel upgrade take?
Most residential upgrades are completed in a day, with power off for part of it. Permit and utility scheduling happen before that day.
Do I need a permit for a panel upgrade in Oakland?
Yes. A service upgrade requires a City of Oakland electrical permit and a final inspection. We file it and attend the inspection.
How do I know if I need 200A?
A load calculation gives the answer properly. As a rule, adding an EV charger, heat pump or induction range to a 100A service is where capacity runs out.
My panel is a Federal Pacific. Is that urgent?
Federal Pacific Stab-Lok panels have a documented history of breakers failing to trip under fault. Replacement is widely recommended and most inspectors will flag it.
Will my power be off all day?
No. The outage window is limited to the changeover itself and is scheduled with PG&E in advance so you can plan around it.
Can you upgrade the panel and install an EV charger together?
Yes, and it is usually cheaper than doing them separately. See the EV charger page for how the two jobs combine.
What does a panel upgrade cost in Oakland?
It depends on service size, mast and meter condition, and the utility connection. You get an itemised written quote after the site visit — no figures over the phone.
