## Electrical Panel Upgrade in Los Gatos, CA

A lot of Los Gatos houses are still running the panel they were built with, on a service sized for one window AC and a black-and-white television. Add an EV, a heat pump and an induction range and that panel is out of room and out of capacity.

Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

## Situations we see in Los Gatos

### 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.

### 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.

### 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 Los Gatos jobs.

## Reviews from Santa Cruz County

★★★★★

Tesla 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.

We needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.

Six recessed lights in the living room and a dimmer that finally doesn't buzz. They laid the whole layout out on the ceiling with tape first, which I appreciated.

## Electrical Panel Upgrade in Los Gatos — questions

How much does an electrical panel upgrade cost in Los Gatos?

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.

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.

Do I need a permit for a panel upgrade in Los Gatos?

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.
