Four Different Jobs, Four Different Prices
Job | Price | What it involves |
|---|---|---|
Sub panel replacement | $1,000 – $5,000 | Replaces a secondary panel. Depends on size and location. |
Main panel replacement | $3,000 – $4,000 | Replaces the main panel. The meter and the service stay exactly where they are. This is what most people mean when they search for panel upgrade cost. |
Meter main load center upgrade | $4,000 – $9,000 | Replaces the combined meter and main disconnect equipment along with the panel. Involves the utility. |
Underground service upgrade, 100A to 200A | $10,000 – $30,000 | Replaces the service itself along with the panel. See our underground service page for why that range is so wide. |
Why the Meter Main Range Is Wide
AFCI and GFCI breakers cost $150 to $250 each. A modern panel built out with combination AFCI/GFCI breakers throughout costs considerably more than one without them, and current code requires them on far more circuits than older code did. That single factor accounts for most of the spread between $4,000 and $9,000 on the same panel.
Signs You Need a Panel Upgrade
Your panel is 60 or 100 amp and you want to add an EV charger, heat pump, hot tub, electric range or ADU.
Your panel is a Zinsco, Federal Pacific Stab-Lok, Challenger or Pushmatic. These have documented failure modes and many insurers now require replacement.
Breakers trip repeatedly under normal loads, or the panel is full with no room for a new circuit.
There is rust, scorching, a burning smell or a warm breaker. Stop using the panel and call an electrician.
A home inspector or insurance carrier flagged the panel during a sale or renewal.
What the Job Includes
Load calculation and equipment sizing. The permit through your city or county. Coordination with PG&E for the service disconnect and reconnect. Removal of the old panel and meter main. Installation of the new panel, breakers, grounding and bonding to current code. Every breaker correctly labeled. Whole-home surge protection at the panel. The final inspection.
Grounding Upgrades
Current code requires two ground rods along with a cold water bond and a gas bond. On older Central Coast homes we rarely find all three present. Grounding is what gives fault current a path back to the source so a breaker can do its job, so an improperly grounded service is a safety issue regardless of how long it has been that way. We correct grounding and bonding as part of every panel and service upgrade.
How Long It Takes
We deliver a quote within about three days. The panel work itself is a one-day job and the power is off for roughly eight hours. If the job includes an underground service upgrade, PG&E's lead time is three to six months from application to energized service — that is utility scheduling, not our crew availability, and it is the part to plan around.
You May Not Need One At All
If the only reason you are considering an upgrade is to add an EV charger, load management can often avoid it. A load-managing charger installed runs $3,300 to $5,300 — less than every panel option above.
How long does a panel upgrade take?
We deliver a quote within about three days. The panel work itself is a one-day job and the power is off for roughly eight hours. If the job includes an underground service upgrade, PG&E's lead time is three to six months from application to energized service.
Will my power be off during the upgrade?
Yes, for roughly eight hours on the day of the panel work.
Do I need a permit for a panel upgrade?
Yes. Panel replacement requires an electrical permit and a final inspection. Inside city limits the permit comes from the city building department; outside, from the county. We pull it as part of the job.
Are Zinsco and Federal Pacific panels dangerous?
Both have documented issues with breakers failing to trip under fault conditions, and California insurance carriers increasingly require replacement. A panel of either brand should be replaced rather than added to.
