## Situations we see in Chula Vista

### 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.

### 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.

### 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 Chula Vista jobs.

## Reviews from San Diego 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.

★★★★★

Added outlets to three bedrooms and a weatherproof one out back. Cuts were small, patches were tidy, and everything got labeled at the panel.

Warehouse high bay retrofit to LED. Did it over a weekend so we never stopped shipping, and the place is twice as bright.

## Electrical Panel Upgrade in Chula Vista — questions

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.

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.

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.

Do I need a permit for a panel upgrade in Chula Vista?

Yes, service work is permitted and inspected. We pull the permit, schedule the inspection and meet the inspector so you don't have to.

How much does an electrical panel upgrade cost in Chula Vista?

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.
