Quick answer
Do you upgrade electrical panels in Brea?
Yes. We cover Brea from our La Mirada shop. When a suite is out of slots or the gear runs warm under normal load, we load-calculate, pull the city permit when required, and coordinate SCE. Every job is different. We provide a custom quote after we see your site. Typical panel upgrade projects often start around $4,957 in labor (14 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum. Call (657) 239-6331.
Panel Upgrades in Brea
Commercial panel upgrades near Brea Mall and Downtown get load calcs, city permits, and a change-out so the suite is dark only while the gear swaps. Gear full of tandems is a panel decision with a written outage plan. Call (657) 239-6331 once you know which suite and which loads matter most.

Brea issues we see with panel upgrades
- Overloaded 100A services: dryer, AC, and kitchen trip the main when they run together
- Federal Pacific, Zinsco, or Pushmatic panels that still turn up here: warm breakers or a main that will not stay reset
- Aluminum or ungrounded branch circuits: two-prong rooms that fail a buyer inspection
- Shared neutrals and kitchens remodeled without a service upgrade: lights flicker when the laundry starts
- Dead outlets and GFCI that will not hold after a storm or a bathroom remodel
About Brea
First Electric is a licensed C-10 shop based in La Mirada (C-10 #1120441). We cover homes and small commercial suites across Brea: Downtown Brea, East Brea, and West Brea.
People call when something stopped working: a dead receptacle, a breaker that will not hold, half a house dark, or a panel that feels warm. We fix that first. When the service is maxed out (no spare slots, unsafe gear, or load that will not support an ADU or Level 2 charger), we plan the upgrade honestly and pull the permit. Fire or life-safety emergency? Call 911 first, then us.
How a commercial panel upgrade works
Assess load and gear
We review the existing panel, connected loads, and planned equipment so the upgrade matches real demand.
Custom written quote
Every job is different. We provide a custom quote after we see your site. Call (657) 239-6331 to schedule around your hours.
Permit and utility
Building permit, inspection, and SCE coordination when the meter or service ampacity changes.
Install in a planned outage
Power is off for the swap. We land circuits cleanly, test, and meet inspection with downtime planned up front.
Timeline
Many small commercial change-outs land in one extended outage window (often 6–12 hours). Utility appointments or larger gear can add schedule time.
Why businesses hire us for panel upgrades
Load calc for the suite
We size for current and planned commercial loads under the California Electrical Code, not a default residential pitch.
Downtime planning
Off-hours and weekend windows when the work allows. You know when power will be off before we start.

Frequently Asked Questions About Panel Upgrades
Process Questions
We do not give blind estimates over the phone. After we understand your Brea project and, when needed, visit the site, we provide a custom written quote with scope and pricing spelled out. Call (657) 239-6331 to start.
Commercial panel or service upgrades often take a full day to several days depending on amperage, switchgear access, and whether work must happen after hours. We plan outages around your operations whenever possible.
Expect rules for working clearances, grounding and bonding, overcurrent protection, labeling, and often AFCI/GFCI where the occupancy requires them. Tenant spaces may also need landlord or property-management approval before the utility cutover.
Yes. California C-10 electrical contractor license #1120441, bonded and insured. You can verify our license status through the CSLB (details on our license page).
Pricing Questions
A 100A-to-200A service upgrade depends on the meter/main location, grounding, conduit, and whether Southern California Edison (SCE) must change the service drop or meter. Every job is different. We provide a custom quote after we see your site. Typical panel upgrade projects often start around $4,957 in labor (14 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.
Many repairs and inspections start with a $189 diagnostic credited toward the job if you hire. Call (657) 239-6331; a real person answers.
Service Questions
Often yes. Many homes only need a new main panel or meter-main while existing branch circuits remain. If we find damaged wiring, aluminum branch circuits that need remediation, knob-and-tube, or overloaded feeders, we recommend targeted repairs or a partial rewire, not a full gut unless the system warrants it.
