Standard 200-Amp Panel Swap
For a standard 200-amp swap with breaker replacement included, our Phoenix project data puts most homes between $1,650 and $2,700. Confirm whether the existing service entrance can remain.

What Is the Average Cost of an Electrical Panel Upgrade?
Phoenix House Rewiring puts most residential electrical panel upgrades in Phoenix at $1,290 to $4,460, with a typical installed project around $2,000 to $2,500. The useful comparison is what each quote includes: a panel swap, an increase in amperage, or replacement of the service entrance as well.
Quick Summary
- A 100-amp to 200-amp upgrade typically costs $1,800 to $3,500, depending on whether the service entrance conductors and meter socket need replacement.
- Labor accounts for roughly 40-50% of the project total. Panel access and utility shutdown coordination affect that cost.
- Permit and City of Phoenix inspection fees typically add $150 to $400. Check whether those fees are already included in the quoted total.
- Most straightforward swaps take one working day; service entrance upgrades or panel relocations can take two to three days.
What Drives Panel Upgrade Pricing
Service Entrance Replacement
Replacing the service entrance, weatherhead, and meter socket can add $800 to $1,500 to the job. Ask whether that work is included in the proposed upgrade.
On-Site Panel Assessment
A useful quote starts with the panel's amperage, age, location, and breaker inventory. Identify planned EV charging, pool equipment, or HVAC circuits before choosing the new capacity.
Panel Conditions That Affect the Quote
60-Amp Fuse Box in an Older Phoenix Home
Older Melrose District bungalows may still have 60-amp fuse boxes. The estimate should account for both the panel and the condition of the wiring it serves.
Accessible 200-Amp Panel on a Garage Wall
A garage-mounted panel with clear access is generally simpler to replace than one in a finished wall or a second-story utility closet. Access helps explain differences between quotes for the same amperage.
Electrical Service Mast, Meter Socket, and Grounding
These components distinguish a full service entrance upgrade from a panel-only swap. Homes built before the 1980s in Encanto and Willo may need this broader scope.
Compare the Parts of Your Estimate
Labor and Utility Coordination
Labor typically runs $600 to $1,800; hourly rates can range from $90 to $180. A flat project quote should account for access and any utility coordination for a temporary power shutdown.
Panel, Breakers, and Grounding Materials
Panel and breaker materials run $400 to $1,200, depending on amperage and equipment selection. Grounding rods, conduit, and connectors can add another $100 to $300.
Permit Fees and Inspection
City of Phoenix permit fees typically run $150 to $350, with inspection included in most cases. Confirm the fee allowance and responsibility for grounding, bonding, circuit labeling, and clearance checks.
Quotes With an Unclear Scope
For a quote below $950, ask exactly which panel work, breakers, permit fees, and inspections are included. Compare written scopes before treating a lower total as a better price.
Phoenix Panel Upgrade Price Ranges
| Panel upgrade scope | Phoenix price range | What to Review in the quote |
|---|---|---|
| 100-amp panel replacement | $800 to $1,800 | Replacement at the same capacity; confirm breaker and grounding work. |
| 150-amp panel upgrade | $1,500 to $2,800 | Panel capacity, equipment selection, and accessibility. |
| Standard 200-amp upgrade | $1,300 to $3,000 | With adequate existing service entrance conductors, includes new breakers, grounding, and permit fees. |
| Full service entrance upgrade | $2,500 to $4,600 | Broader work including a new meter socket and grounding; confirm whether the mast and conductors need replacement. |
| 400-amp panel for a large home | $3,500 to $6,000+ | Higher-capacity equipment and service requirements for a large home. |
Why Panel Upgrade Averages Differ
Phoenix pricing data puts the local average around $2,180, but a basic replacement and a full service upgrade cover different work. For historical comparison, basic panel replacement nationally averaged $1,341 in 2025, within a broader $500 to $2,500 range. Complex full-service projects involving rewiring ran $5,000 to $30,000 in that national comparison. Locally, larger upgrades with a new mast, meter socket, and grounding electrode system run $3,500 to $4,600. A panel upgrade replaces the distribution point; whole house rewiring replaces conductors serving outlets, switches, and fixtures, so the two scopes should be priced separately.
Additional Work That Changes the Total
A finished wall, difficult access, or deteriorated wiring can expand the work beyond the panel. Aluminum branch wiring in homes from the 1960s and 1970s, or older knob and tube wiring in Coronado and Garfield homes, needs evaluation before the new panel is connected. If the project also adds protection or circuits, ask for separate prices: individual breaker replacement runs $150 to $350, GFCI outlet installation $120 to $220 per location including labor, and dedicated circuits $250 to $800 depending on distance and wire gauge. Whole-home surge protection installed at the panel runs $300 to $650. An electrical safety inspection covering panel condition, wiring, and grounding runs $150 to $300.
Common Follow-Up Questions
Is the upgrade worth it? A fuse box, recurring breaker trips, or plans for an EV charger or new HVAC circuit are reasons to have the panel evaluated; a panel over 25 years old also deserves a condition review. Does replacement increase resale value? It can address an inspection concern, but there is no fixed dollar-for-dollar return. How long does the full process take? Allow about one to two weeks from the initial site visit through installation, including permit processing, with the physical swap usually taking one day. Can you do it yourself to save labor? Panel work involves service entrance conductors and utility disconnection, so use a qualified electrician.
