Panel Upgrades in La Puente
Commercial panel upgrades near Hacienda Blvd get load calcs, city permits, and a change-out window that protects opening hours. Gear full of tandems is a panel decision, not a breaker-swap loop. We coordinate SCE when the meter moves. Call (657) 239-6331 once you know which loads matter most.

La Puente issues we see with panel upgrades

About La Puente
First Electric is a licensed C-10 shop based in La Mirada (C-10 #1120441). We cover homes and small commercial suites across La Puente: Downtown La Puente, East La Puente, and West La Puente.
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 La Puente 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.
Yes. Commercial service and panel work needs permits and inspection. We handle permitting and coordinate with the building department and utility when service equipment changes.
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.
Most panel change-outs take one day (often 4-8 hours of power-off work). Utility meter appointments, underground service, or a full service relocation can add schedule time. We confirm the timeline after we see your panel and coordinate with the utility when needed.
