MAIN 200AElectrical Panel Upgrade in Loomis, CA
Panel upgrades are the job that unlocks everything else. In Loomis and across Placer County, most requests for EV charging, heat pumps or ADU power start with a service upgrade from 100 amps to 200, because there is simply nowhere left to land a new breaker.

Situations we see in Loomis
Adding an EV, heat pump or ADU
All of these need a load calculation. If existing demand plus the new load exceeds your service, the upgrade comes first.
Zinsco or Federal Pacific panel
These breakers have a documented history of failing to trip under fault. Replacement is the only real remedy, and it is one of our most common Loomis jobs.
No space left in the panel
Double-tapped breakers and tandem cheaters are a sign the panel is full. A 200 amp replacement gives you 40 or more spaces and room for the next ten years.
Panel is rusted or wet
Water in an enclosure corrodes bus stabs and creates high-resistance connections. Once rust reaches the bus, the panel is done.

Reviews from Placer County
Standby generator install. They sized it to what we actually use rather than the biggest unit, then walked me through the transfer switch and the exercise cycle.
Renee B.Generator · LoomisFlickering through the whole house turned out to be a loose neutral at the service. They found it in under an hour when two other companies had shrugged.
Bill T.Troubleshooting · LoomisTesla Wall Connector in the garage, clean conduit run, done in an afternoon. They talked me out of a panel upgrade I didn't actually need.
Devon W.EV charger · LoomisElectrical Panel Upgrade in Loomis — questions
Do I need a permit for a panel upgrade in Loomis?
Yes, service work is permitted and inspected. We pull the permit, schedule the inspection and meet the inspector so you don't have to.
Do I really need 200 amps?
If you are adding EV charging, electric heat, a hot tub or an ADU, almost certainly. We run an actual load calculation rather than guessing, and if 100 amps genuinely still works we will tell you.
Can you replace just the breakers instead of the whole panel?
Sometimes. On a sound modern panel, breaker replacement is fine. On a Zinsco, Federal Pacific or corroded enclosure, new breakers don't fix the bus, so the panel gets replaced.
How long will my power be off during the upgrade?
Plan on most of a working day. We coordinate the utility disconnect and reconnect so the outage lands in one block rather than spread over days.
How much does an electrical panel upgrade cost in Loomis?
Cost tracks the service size, the condition of the service entrance and whether the meter has to move. A straight 100 to 200 amp swap sits well below a job that needs a new mast and underground feed. Call (833) 652-8933 and we will walk your panel and quote a flat number.
