Quick answer
Do you upgrade electrical panels in Whittier?
Yes. We cover Whittier 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 Whittier
Commercial panel upgrades for Whittier shops and suites get load calcs, City of Whittier permits, and a change-out window around opening hours. Greenleaf storefronts and warehouse bays both need real-load sizing, not a one-size board swap. We coordinate SCE when the meter moves and document historic or mixed-use constraints when the building requires extra care. Call (657) 239-6331 with suite hours up front.

Whittier issues we see with panel upgrades
- Overloaded 100A services in East and South Whittier tracts: kitchen and AC trip the main together
- Federal Pacific, Zinsco, or Pushmatic panels that still turn up in mid-century stock: warm breakers or a main that will not stay reset
- Aluminum or ungrounded branch circuits in older Uptown plaster homes: two-prong rooms that fail a buyer inspection
- Greenleaf storefront faults: dead circuits before opening, no spare slots for a remodel
- Dead outlets and GFCI that will not hold after a storm or bathroom remodel
About Whittier
First Electric is a licensed C-10 shop based in La Mirada (C-10 #1120441). We cover Uptown historic and plaster homes, East and South Whittier tracts, West Whittier edges, and small commercial suites on Greenleaf.
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.

Yes. Panel and service upgrades need a permit and inspection. We pull the permit, schedule the inspection, and work with your building department and the utility when the service entrance changes.
Power must be off for the cutover. Many Whittier businesses schedule night or weekend windows so customers are not impacted. We coordinate the outage plan before work starts.
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.
