A meaningful share of homes in Coronado, CA are still running on electrical panels that were sized and installed for a household that no longer exists.
That's the gap most homeowners discover the hard way: a breaker that won't stop tripping, lights that dim when the AC cycles, or an inspector flagging the brand on the door.
Panel Services We Offer
200 Amp Service Upgrade & Installation
The standard upgrade for modern household demand. Includes the new panel, service entrance conductors, meter base if needed, grounding system upgrade where required, and full coordination with the local utility.
Ideal for homes with central HVAC, EV charging, electric appliances, and finished basements.
Main Electrical Panel Replacement
When the existing panel is at end-of-life, has been flagged by an insurance carrier, or is from a manufacturer with documented safety concerns.
Federal Pacific & Zinsco Panel Replacement
Both manufacturers produced panels with well-documented failure modes. We replace these panels routinely in Coronado, CA.
Sub-Panel Installation
For garages, finished basements, workshops, accessory dwelling units, or any addition pulling enough load.
Main Panel Repair & Component Replacement
Not every panel issue requires replacement. A failed main breaker, loose lug, damaged neutral — these are repairable. We diagnose first.
Service Panel Inspection & Insurance Documentation
Required when buying, selling, renewing insurance, or refinancing. We provide a detailed written report.
Service Entrance Upgrade
Meter base, mast, weather head, and service entrance conductors upgraded to current code.

Electrical Panel Upgrade & Repair in Coronado: Myths Worth Clearing Up
"If my panel is working, it's fine." Not always. Federal Pacific panels often "work" until they don't trip during an overcurrent event.
"100 amps is enough for any home." For modern Coronado homes with EV chargers, central air, and electric appliances — no.
"Upgrading the panel will lower my electric bill." It improves capacity and safety, not efficiency.
"Panel upgrades take a week." Almost never. A standard 200 amp upgrade is a one-day job.
Standards We Hold Every Job To
- Licensed electrician on-site for the entire job
- Permit pulled before work begins
- Branch circuits documented and labeled
- Grounding system verified and upgraded
- Surge protection offered as part of upgrade
- Full walkthrough and documentation
A Few Local Realities
Older neighborhoods in Coronado frequently include Federal Pacific or Zinsco panels. Some streets have aluminum branch wiring. These are typical conditions we plan for in Coronado, CA.
When a Panel Repair Beats a Full Replacement
The default recommendation tends to be "replace the panel." But it's not always the right answer.
Common repairable failures we see:
- A failed main breaker
- A loose main lug
- A damaged or burnt neutral
- A faulted single bus connection
We diagnose first. We recommend replacement only when it's the right answer.
