Panel Upgrades in Cerritos
Commercial panel upgrades for Towne Center and Auto Square suites get load calcs, city permits, and a written outage plan. Gear full of tandems or warm under tenant lighting is a panel decision. We schedule the change-out so the suite is dark only while the gear swaps. Call (657) 239-6331 once you know which loads matter most.

Cerritos 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 Cerritos
First Electric is a licensed C-10 shop based in La Mirada (C-10 #1120441). We cover homes and small commercial suites across Cerritos: Cerritos Towne Center, East Cerritos, and West Cerritos.
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.
Licensed and checkable
C-10 #1120441. Bonded and insured. Verify on our license page.
Permit path included
City inspection and utility coordination are part of the job, not your homework after the fact.

Service Questions
Size follows a real load calculation: connected equipment, continuous loads, HVAC, kitchen or process gear, and planned expansion. We measure demand and recommend amperage that passes inspection without oversized guesswork.
Frequent breaker trips, warm or buzzing panels, flickering lights when large loads start, a full panel with no spare slots, Federal Pacific / Zinsco / Pushmatic equipment, or a 60-100A main when you want EV or HVAC upgrades. Any burning smell or sparking at the panel is an emergency.
