Electrical Panel Upgrade Upland CA Done Right the First Time
An Electrical Panel Upgrade Upland CA homeowners can count on starts with a real load calculation, not a guess. We swap outdated fuse boxes and failing panels for Square D and Eaton gear, pull the city electrical permit, and leave you with labeled circuits and AFCI protection. Most homes are back on in a single day.

Electrical Panel Upgrade Upland CA Built on Code-Correct Work
We start by pulling the dead front and reading the existing service. Then we run a load calculation, check torque on every breaker terminal, and test each circuit before the new panel goes in. You get the labels and a short written summary at the end.
We handle Electrical Panel Upgrade Upland CA work for houses from Historic Downtown Upland bungalows to The Colonies two-story plans. That means 100 to 200 amp service upgrades, subpanel additions, meter main replacements, and fuse box conversions, all wired to the California Electrical Code and NEC 2020 standards. Every job starts with a load calculation so the panel you buy actually fits the house.
What separates us is the paperwork and the follow-through. We pull the city electrical permit, coordinate the utility disconnect, and hand you a labeled panel plus a written summary of what changed. Homeowners in San Antonio Heights and North Upland call us for affordable breaker panel replacement Upland because we quote the job before we cut power, not after.

Panel and Service Work We Handle
Every job below starts with a walkthrough and a load calculation, whether you need a 100 amp panel or a 400 amp service for an EV charger and solar.
100 to 200 Amp Service Upgrade
The standard upgrade for older Upland homes still running 60 or 100 amp service.
200 to 400 Amp Service Upgrade
Built for larger homes adding EV chargers, solar, or a detached ADU. A 400 amp service splits into two 200 amp panels so you keep room for future circuits.
Subpanel Installation
A subpanel in the garage or at the back of the house shortens circuit runs and clears space in a crowded main panel.
Fuse Box to Breaker Panel Conversion
Old fuse boxes in Historic Downtown Upland homes cannot take AFCI or GFCI protection and often have no main disconnect.
Outdated Panel Replacement
Federal Pacific and Zinsco panels are known failure points, and insurance carriers in Upland increasingly ask about them.
AFCI and GFCI Breaker Installation
AFCI breakers protect bedrooms and living areas from arc faults; GFCI breakers protect kitchens, baths, laundry, and garage circuits.

What shapes your panel quote
Every panel job is priced after we see the service size, the meter location, and what the branch wiring looks like behind the dead front.
How estimates work
We inspect the panel and run a load calculation, then hand you a written scope with the amperage and parts listed.
Request pricingHow much service does the house need?
Fits small homes with gas appliances and no EV charging planned.
Where does the panel and meter sit?
Easiest access, shortest conduit runs, and the simplest swap.
What is behind the dead front?
Clean terminations, so the swap stays close to a like-for-like job.
How a Panel Upgrade Actually Goes
From the first call to the inspector signing off, here is the sequence we follow on every Electrical Panel Upgrade Upland CA job. You will know what is happening and when the power comes back on.
Walkthrough and Load Calc
We inspect the existing panel, meter main, and service mast, then run a load calculation on your appliances and square footage. You get a written scope and a fixed price before anything is ordered.
Permit and Scheduling
We file the city electrical permit and schedule the utility disconnect. Most Upland jobs get on the calendar within the same week, and we confirm the day and the power-off window with you in advance.
Panel and Service Swap
Power off, old panel out, new panel and meter main in. We torque every breaker terminal, land the grounding electrode conductor, and install AFCI and GFCI breakers where the code calls for them.
Test, Label, and Inspect
We test each circuit with a voltage tester and circuit breaker finder, print the panel labels, and walk the inspector through the work. You get the signed inspection card and a written summary of the job.
Panel Problems We Fix in Upland Homes
Most calls start with a symptom, not a diagnosis. Here are the ones we see most often in Upland, and what it takes to fix them properly.
That is an overloaded electrical panel, not a bad breaker. We run a load calculation, and if the service is undersized we upgrade to 200 amps with a new meter main and correctly sized feeders.
Meter Main and Service Mast Replacement
These panels have a documented failure history and parts are scarce.
Outdated Panel Replacement
A fuse box cannot accept modern arc-fault or ground-fault breakers, which is a real safety gap in bedrooms and kitchens.
AFCI and GFCI Breaker InstallationA cracked mast or corroded meter main fails inspection and can drop the utility drop. We replace both, re-terminate the service conductors, and restore correct clearances. This is the repair that gets a red-tagged service back online.
Meter Main and Service Mast ReplacementWe verify your busbar rating and open capacity first. If there is room, we add the 240V circuit and a whole home surge protection and panel upgrade Upland CA setup in one visit.
Whole-Home Surge ProtectionWhat Upland Customers Say
Our 1950s house near Historic Downtown still had the original fuse box. They converted it to a breaker panel, labeled everything, and walked me through which breaker runs the kitchen. The inspector signed off the same day. Power was back on before dinner.
I needed a 200 amp upgrade to add a Level 2 charger for my truck. They ran the load calculation, showed me why 100 amps would not cut it, and had the new panel and meter main in over two days. Clean conduit work, no surprises on the invoice.
Our Zinsco panel was scaring the insurance company. They replaced it with an Eaton panel, found heat damage on two branch circuits, and fixed the aluminum wiring terminations. Took a full day and the price matched the quote to the dollar.
Storm took out our service mast last winter. They came out, replaced the mast and meter main, and got the utility to reconnect. Communication was good, though we waited a couple extra days for the inspection slot. Work itself was solid.
We manage several rentals around Upland Palms and College Heights. They have done three panel swaps for us now, always pull the permit, and always leave the panel labeled. Tenants barely notice the power going off for the day.
Breakers kept tripping whenever the AC kicked on. They ran the numbers, upsized us to 200 amps, and added a whole-home surge protector while the panel was open. No more tripping, and the price was fair for the scope.

Electrical Panel Upgrade Upland CA Questions
The questions we get most often about panel work in Upland, answered straight.
Still have a question?
Describe what you are seeing and we will point you to the right next step.
(909) 850-3163A like-for-like breaker panel swap in Upland typically runs $1,850 to $2,900, while a full 200 amp service upgrade with a new meter main and mast lands between $3,200 and $5,400. A 400 amp dual-panel setup for an EV and solar runs $6,500 to $9,800. The load calculation and panel location drive the final number.
Look for a C-10 Electrical Contractor License, a willingness to pull the city permit, and a crew that runs a load calculation before quoting. We do all three, work to NEC 2020 and California Electrical Code, and leave every panel labeled. Ask any contractor for their license number and permit history before you hire.
Yes. The City of Upland requires an electrical permit for a panel or service change, and the work has to pass inspection. Unpermitted panel swaps can surface during a home sale and give an insurer grounds to deny a claim. We file the permit and meet the inspector on site as part of the job.
Most single-family homes in Upland do fine on 200 amps, which covers central AC, an electric range, a dryer, and a future EV charger. Homes over 3,000 square feet or those adding solar and an ADU often go to 400 amps split across two panels. We confirm with a load calculation rather than guessing.
We handle emergency breaker panel replacement Upland CA calls for dead panels, burning smells, and storm-damaged service masts, and we keep after-hours slots for those situations.
