Electrical Panel Upgrade in California

Your electrical panel sets the limit on everything else in the building. If yours is full, outdated or only rated for 100 amps, adding an EV charger, air conditioning or an induction range can push it past what it was built for. An electrical panel upgrade in California gives you the capacity and the breaker protection modern loads need.

Electrical Panel Upgrade cost in California

Electrical panel upgrade cost in California depends on the amperage, whether the service is overhead or underground, where the meter sits, and what the utility and building department require. A like-for-like panel swap is at the low end; relocating the service or upgrading 100 amp to 200 amp with new grounding costs more. We inspect the existing setup and give you a written, itemized price.

Electrical Panel Upgrade FAQs

How long will my power be off?

For most panel upgrades in California the power is off for one working day, typically four to eight hours. We schedule the utility disconnect and reconnect so the outage is as short as possible.

Do I need 200 amps?

If you plan to add an EV charger, electric heat pump, induction range or solar, usually yes. We run a load calculation on your property so the decision is based on numbers, not a sales pitch.

Is a permit required for a panel upgrade in California?

Yes. Panel and service upgrades require a permit and inspection, and the utility has to approve the reconnection. We handle all of it.

My panel is an older brand people warn about. Should I replace it?

Some older panel designs have breakers that can fail to trip. If yours is one of them, or shows heat damage, replacement is the safe choice. We'll open it and show you what we find.

Can you add a subpanel instead?

If the main service has spare capacity but no spare slots, a subpanel is often the cheaper answer. If the service itself is undersized, a subpanel will not help. See dedicated circuits and EV charger installation for common reasons to upgrade.
