Commercial Electrical Upgrades in Commerce, CA
Commercial electrical upgrades in Commerce (Downtown Commerce). C-10 #1120441. Call (657) 239-6331.
Quick answer
Do you rewire suites and small commercial in Commerce?
Yes when the branch wiring itself is the problem (aluminum, ungrounded, cloth), not only the panel. We cover Commerce from our La Mirada shop. We scope panel-only versus rewire-heavy after a walkthrough. Every job is different. We provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum. Call (657) 239-6331.
Electrical Upgrades in Commerce
Commercial electrical upgrades in the Industrial District (feeders, distribution, and lighting) follow California Electrical Code. Flex suites that grew into denser lighting or process equipment often need feeder and branch work. Downtime is planned into the quote so a machine bay is not dark longer than the scope. Call (657) 239-6331 with the suite address and what loads you cannot lose.

Commerce issues we see with electrical upgrades
- Warehouse and flex-space panels that run hot or trip under tenant machinery load
- Tenant-suite faults: dead circuits before opening, no spare slots for TI work
- Overloaded residential services in nearby tracts: dryer and AC trip the main together
- Federal Pacific, Zinsco, or Pushmatic panels that still turn up in mid-century houses: warm breakers or a main that will not stay reset

About Commerce
First Electric is a licensed C-10 shop based in La Mirada (C-10 #1120441). We cover homes and small commercial suites across Commerce: Downtown Commerce, Industrial District, and Residential Commerce.
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 upgrade usually runs
Walk the suite
We look at the panel, accessible wiring, equipment loads, and problem areas. You get an honest scope: targeted vs broader upgrade.
Written plan and quote
Every job is different. We provide a custom quote after we see your site. Includes outage windows, sequencing, and what other trades need to know.
Permit and protect
We pull permits when required, protect finished areas, and stage work so inspection milestones are clear.
Install, test, inspect
New circuits, devices, and protections as scoped. Test under load when possible, then city sign-off when required.
Timeline
Targeted upgrades may finish in a day or two. Broader suite rewires run longer and often need off-hours blocks. We set expectations after the walkthrough.
Why businesses trust us with upgrades
Right-size the scope
Smallest correct fix first. Full gut only when the distribution system warrants it.
Operations-aware scheduling
Off-hours and phased cutovers when the work allows so customers and staff are not stranded.

Frequently Asked Questions About Electrical Upgrades
Process Questions
We do not give blind estimates over the phone. After we understand your Commerce 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.
Pricing Questions
Commercial upgrade and TI pricing depends on infrastructure and equipment load. Every job is different. We provide a custom quote after we see your site. Typical commercial electrical projects often start around $2,832 in labor (8 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.
Rewire pricing depends on access (attic/crawlspace vs walls open), knob-and-tube or aluminum remediation, panel condition, and finish repairs. A ~2000 sq ft home is not a fixed package price. Every job is different. We provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.
Service Questions
Yes, new kitchens, medical gear, CNC, EV fleets, and HVAC often need feeders, panels, or 3-phase work. We load-calculate and design additions that pass inspection without overselling gear.
Age alone is not the rule, condition is. Many 60-70 year old Commerce homes still have original cloth, knob-and-tube, ungrounded circuits, or overloaded panels. If circuits are brittle, ungrounded, aluminum branch wire, or failing inspection/insurance review, a partial or full rewire is often the right long-term fix.
Yes. We replace overloaded panels, upgrade services when needed, and coordinate inspections. 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.
Yes. When aluminum, ungrounded, or undersized branch wiring is the root problem, we plan a whole-home rewire or major upgrade. Every job is different. We provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.
