Electrical Panel Upgrades in Los Angeles & Orange County
Replace an outdated, undersized, or unsafe panel with modern service sized for today's loads — EVs, HVAC, home offices, and everything else your home or business runs now that it didn't 20 years ago.
A panel upgrade starts with a load calculation — figuring out what your home or business actually draws right now, and what it's likely to draw soon: an EV charger, a heat pump, a home office setup, or expanded commercial equipment. The new panel gets sized to comfortably cover that, not just to meet it, because a panel that's already at its limit on day one leaves no room for the next addition without another disruptive upgrade.
Older panels are often the actual bottleneck behind problems that look unrelated. A 100-amp service that was adequate for a smaller home decades ago can't comfortably support central air, an EV charger, and a modern kitchen's appliance load all at once — and the symptoms show up as tripped breakers or dimming lights rather than an obvious panel failure. Some panel brands carry a well-documented history worth knowing about specifically: Federal Pacific and Zinsco panels are the two most frequently flagged in home inspections nationally, for breakers that don't reliably trip when they should.
The physical work is a coordinated sequence rather than a single step. We handle the permit, then schedule a service disconnect and reconnect with the utility — this is the part that actually determines when your power is briefly out, and we plan that window around your schedule where possible rather than leaving it open-ended. The panel and meter socket get swapped, every circuit gets re-landed and clearly labeled (not left as a mystery for the next person to trace), and grounding and bonding get verified to current code, which older installations frequently lack.
Before anything is re-energized, the work gets inspected. That inspection is your assurance that the new service was actually installed correctly, not just that it looks finished — and it's not a step we skip or work around.
For commercial properties, panel upgrades often come bundled with a broader capacity need — added equipment, a tenant improvement project, or a planned expansion — and we scope the panel size around where the building is headed, not just where it is today.
Commercial Service Upgrades: 400A and 800A
On commercial buildings, a panel job is often part of a bigger capacity question. New equipment, a tenant improvement or a planned expansion can push a building past its existing service. We scope commercial service upgrades, including 400A and 800A services, from a load calculation, then line up the permit, the utility and the shutdown window so your operation loses as little working time as possible. For homes, the most common job is still an old fuse box or 100A panel moving to 200A service.
Utility Coordination with SCE and LADWP
Every panel swap needs the utility to disconnect and reconnect service. Across most of our service area that's Southern California Edison. Inside the City of Los Angeles it's LADWP, and Anaheim runs its own utility. We schedule that window for you, so you know ahead of time when the power goes off.
Signs You Might Need One
Is This the Right Service?
- A fuse box, or a panel more than 20–25 years old
- Breakers that trip when you run more than one major appliance
- Lights that dim or flicker when the AC or a big appliance starts
- No room left to add circuits for a remodel or new equipment
- A panel brand with a well-documented safety history (Federal Pacific and Zinsco panels are the two most commonly flagged in home inspections)
How It Works
Our Process
Load Calculation & Assessment
We check your current and near-future power needs before recommending a size.
Permit & Utility Coordination
We handle the permit and schedule the utility disconnect/reconnect.
Panel Swap
The physical swap happens during a scheduled outage window, not an open-ended one.
Inspection & Re-Energize
Signed off by the inspector, then powered back up and tested.
Where We Do This Work
We upgrade panels for homes and businesses from Santa Fe Springs out to Whittier, Downey, Norwalk, La Mirada, Buena Park and Fullerton.
Residential & Commercial
We Handle This for Both
Whether it's your home or your business, this service is scoped and scheduled to fit the property.

How long does a panel upgrade take?
The physical swap is usually a single day; the outage window itself is typically just a few hours, scheduled in advance.
Will I be without power the whole time?
No — only during the scheduled swap window, which we coordinate around your schedule where possible.
Do I need a permit for a panel upgrade?
Yes, and we handle that as part of the job.
