Electrical Panel Upgrades for Campbell Properties
Most of the panel work we do in Campbell traces back to one era: the 1950s and '60s tract-home boom that filled out San Tomas, Hacienda Park, White Oaks, and Capri after the orchards came down. Those homes were wired for a 1955 life — a fridge, a TV, and a couple of lamps — and a lot of them still carry the original 100-amp service or, in the older Budd Avenue and Downtown Campbell craftsman cottages from the 1920s and '30s, a fuse box that was never meant to run an EV charger, a heat pump, and an induction range at once. When a Campbell homeowner calls about flickering lights or a panel that runs warm, the root cause is usually that mid-century service trying to do a 2026 job. The newer infill condos near the Pruneyard and along Hamilton Avenue are the opposite problem — they have modern panels but no spare capacity once a home office and a car charger get added. Fox Electric upgrades these Campbell services to a modern 200-amp panel, sized with a real load calculation so you have headroom for whatever comes next, whether that's a backyard ADU on a deep San Tomas lot or a second EV.
In Campbell the service disconnect and reconnect runs through PG&E, and the permit and electrical inspection go through the City of Campbell building department — we coordinate both so you don't have to. The 1950s-60s tract homes here often sit on slabs with the panel on an exterior stucco wall, which keeps the swap clean but means new branch circuits get planned around the slab rather than an attic. Older Downtown and Budd Avenue cottages sometimes hide cloth or knob-and-tube wiring behind that fuse box, worth checking before the panel goes in.
Electrical project resources for Campbell
Campbell organizes applications by project group in MGO Connect, its online permit portal. Electrical service upgrades appear under General Trade Permits, while commercial tenant improvements and renewable-energy projects use separate guidance. If a new circuit is part of a remodel, describe the whole alteration before selecting a trade-only path. The project guide, not the portal name, determines the appropriate group.

Campbell FAQ
Does a Campbell panel upgrade go through PG&E or the city?
Both, in different roles. PG&E handles the actual service disconnect and reconnect at the meter, while the City of Campbell building department issues the electrical permit and sends an inspector to sign off. We pull the permit and schedule the PG&E window for you, so it's one coordinated job rather than two phone trees.
My 1960s San Tomas home still has a 100-amp panel and we're adding an EV. Do we need 200 amps?
Often yes, but we confirm it with a load calculation before quoting anything. A lot of these tract homes can take an EV charger with a load-management device instead of a full upgrade. If you're also eyeing a heat pump or induction range, going to 200 amps usually makes the next install plug-and-play, so we size it for what you're actually planning.
Will upgrading the panel mean tearing into my walls?
Usually not much. Most Campbell tract homes from the '50s and '60s have the panel on an exterior wall, so the swap itself is contained. Any new circuits we add get routed around the slab and exterior walls rather than fished through a nonexistent attic, which keeps drywall damage minimal and the work tidy.
Do older Downtown Campbell or Budd Avenue homes need rewiring along with the panel?
Sometimes. Those 1920s-30s craftsman cottages occasionally have cloth-insulated or knob-and-tube wiring behind the original fuse box. We check during the load walkthrough and tell you honestly whether the panel upgrade stands on its own or whether a section of wiring is worth addressing at the same time — no upselling a full rewire you don't need.
How long will my power be off during the upgrade?
The outage window depends on the approved work, PG&E scheduling and the required Campbell inspections. Confirm the disconnect and reconnect arrangements before the installation date, including what happens if work or inspection takes longer than planned.
Will a new panel force AFCI and GFCI breakers throughout my Campbell house?
No. Campbell's MEP application guide states that a panel replacement will not trigger AFCI or GFCI requirements, though the city recommends the upgrade; the panel and breakers must be of matching type and manufacturer and every breaker labeled.
Can an underground service be upsized to 200 A?
Usually, but Campbell's guide warns that underground service wires may limit the ability to upsize and can create other restrictions, so the lateral size is confirmed with PG&E through the Your Projects application before the meter-main is ordered.

Can a 100-Amp Panel Handle an EV Charger?
A 100-amp label is a starting fact. Demand, equipment condition, circuit space, and charging needs determine the installation.
