What this covers

100 to 200 amp service upgrades

The standard move for a California home adding air conditioning, an EV charger, a heat pump or a kitchen remodel. New panel, new meter main, new grounding.

Fuse box replacement

Screw-in fuses cannot protect modern branch circuits or handle today's loads. We swap the whole assembly for a breaker panel.

Obsolete panel replacement

Federal Pacific Stab-Lok, Zinsco and Challenger panels have known breaker failure histories. Replacement is the only real fix.

Sub panels

Feeding a detached garage, workshop, ADU or addition without overloading the main. Sized for what you will actually plug in.

Permits and utility coordination

A service change means a permit, an inspection and a power drop from the utility. We schedule all three so you are not chasing anyone.

Whole-home surge protection

A panel-mounted surge device is the cheapest insurance you can buy for a house full of electronics. Installed at the same visit.

Questions

How much does an electrical panel upgrade cost in California?

Price depends on the amperage you need, whether the meter main and service entrance are being replaced, how the run to the utility is configured and what the panel location requires. We quote the whole job as one flat number for California homes before any work starts, so call (833) 652-8933 and we will price your exact setup.

How long does a panel upgrade take?

Most residential service upgrades in California are a single day on site, with power off for a portion of it. Add time if the utility needs to schedule the disconnect and reconnect, which we book in advance so it lines up with our crew.

Do I need a permit for a panel upgrade in California?

Yes. A service change is permitted and inspected work in California, and the utility will not reconnect without a signed inspection. We pull the permit, meet the inspector and coordinate the reconnect as part of the job.

Do I really need 200 amps?

Not always. A modest California home with gas heat and cooking may be fine at 100 or 125 amps. But if you are adding an EV charger, electric range, heat pump or a large air conditioner, 200 amps stops you paying twice. We run the load calculation before recommending anything.

How do I know my panel is failing?

Warmth on the panel cover, a buzzing or crackling sound, a burning smell, breakers that trip with normal load, rust inside the enclosure or scorch marks on the bus are all end-of-life signs. If you see any of these in California, call (833) 652-8933 rather than waiting.
