Commercial Panel & Service Upgrades
When your building trips breakers, runs out of panel space, or can't power what you're adding, it's time to upgrade the service, not just the wiring.
Commercial panel and service upgrades that add real capacity
Genius Electric handles commercial panel and service upgrades across the Antelope Valley, the High Desert and Victor Valley, Santa Clarita, Greater Los Angeles, and the Inland Empire. When a building outgrows its electrical service, the signs show up fast: breakers that trip once a few loads run together, a panel packed with no open slots, or new equipment the service was never sized to feed. Those aren't wiring faults you chase down and repair. They're capacity limits, and capacity is fixed on the service side.
This is different from day-to-day wiring and repair work. The service itself is what changes: upgrading to 100, 200, or 400 amps, replacing an outdated or unsafe panel, updating the meter and service-entrance, adding a subpanel or service disconnect, and sizing the whole thing for your load and to current code. Get the service right and every circuit downstream finally has room to work.
As an owner-operated, licensed, bonded and insured electrical contractor, Edgar runs the load calculation, gives you a free upfront estimate, pulls the permit, coordinates the utility cutover around your hours, and sees the job through inspection. You end up with a safe, correctly labeled panel and the headroom to add equipment, HVAC, or EV charging without booking another upgrade next year.
Service-side electrical, sized for how your building actually runs
A service upgrade isn't just a bigger box on the wall. It's a load calculation, a meter and service-entrance that can carry it, a panel with room to grow, and clean coordination with the utility and inspector. Here's the service-side work Genius Electric handles for commercial buildings across Southern California.
- 100, 200, and 400-amp commercial service upgrades when a building has outgrown its power or is taking on new equipment
- Meter, service-entrance, and mast work, including weatherhead and service-conductor replacement
- Replacing outdated, overloaded, or unsafe panels, double-tapped breakers, and panels that can no longer be serviced or fitted with parts
- Load calculations and capacity planning so the new service is sized for today's equipment and tomorrow's additions
- Subpanels that extend distribution to a new area, suite, or machine without maxing out the main
- Service disconnects and correctly rated main breakers so the building has a safe, code-compliant point of shutoff
- Added capacity for HVAC, refrigeration, Level 2 EV charging, and other high-draw commercial loads
- Code-compliant work with permits pulled and utility coordination handled from the first call through final inspection
- Clearly labeled panel directories so your staff and the next electrician know exactly what feeds what
If you're not sure whether you need a full service upgrade or just a subpanel to buy some headroom, that's exactly what the site visit and load calculation are for.
How It Works
A Straightforward Process
- 01
Load assessment and capacity planning
We walk the site, open the panel, and review your existing service against the equipment feeding off it, then run a load calculation. That tells us whether you need 100, 200, or 400 amps, a subpanel, or simply a safer panel, and how much room to build in for what's coming next.
- 02
Free upfront estimate and scope
You get a clear written estimate covering the panel or service work, the meter and service-entrance if they're involved, permits, and utility coordination, with no surprises. We also flag anything that has to be brought up to current code as part of the upgrade.
- 03
Scheduled cutover with minimal downtime
Cutting over a service means the power is off for a stretch, so we plan it around your operation, before you open, after close, or on your slowest day, and line up the utility disconnect and reconnect so the building is dark for as little time as possible.
- 04
Inspection, sign-off, and walkthrough
We call for the required inspection, get the work signed off, label the new panel directory, and walk you through what changed, how much capacity you now have, and what that means for adding equipment later.

Commercial Panel & Service Upgrades Questions
Straight answers about commercial panel & service upgrades — and how we approach it for businesses.
How do I know if my business needs a service upgrade or just an electrical repair?
If a single fault keeps tripping one breaker, a repair usually fixes it. If breakers trip whenever a few things run at once, your panel is full with no open slots, or you're adding equipment the building was never wired for, that's a capacity problem, and no amount of repair adds amps. A load calculation settles it. We measure what you're actually drawing before recommending anything.
What amperage does my building need, 100, 200, or 400?
It depends on your connected load and your plans, not a rule of thumb. Small offices and retail spaces often run fine on 200 amps; a building adding HVAC, refrigeration, EV charging, or shop equipment may need 400 or a subpanel to spread the load. We run the numbers on your actual and planned equipment and size the service so you're not upgrading again in two years.
Will you have to shut off power, and for how long?
Some downtime is unavoidable, cutting over a service or swapping a panel means the power is off for part of the job, and part of that window is the utility disconnecting and reconnecting. We schedule the work around your hours, before you open, after close, or on your slowest day, and coordinate the utility so the outage is as short as possible. You'll know the window before we start.
My panel is old, do I have to replace the whole thing?
Not always. Some older or overloaded panels genuinely need replacing for safety; in other cases, adding a subpanel or upgrading a specific part of the service gets you the capacity and safety you need without a full service change. We'll tell you honestly which one your situation calls for after we see the panel and run the load.
Can you upgrade our panel to support a new EV charger, HVAC unit, or added equipment?
That's one of the most common reasons businesses call. New high-draw equipment often needs more capacity than the existing service has room for. We calculate the added load, confirm whether your current service can carry it, and upgrade the panel or add a subpanel and service capacity so the new equipment gets clean, dedicated, code-compliant power.
Do you handle permits and utility coordination?
Yes. Service and panel work is permitted and inspected, and a service change involves the utility disconnecting and reconnecting your power. We pull the permit, coordinate the cutover with the utility, and see the job through inspection and sign-off, so you're not chasing paperwork or scheduling the shutoff yourself.
