Phoenix heat is hard on aluminum bus bars and on 100-amp services that were never meant to run two air conditioners and an EV charger. That is why Valley electricians talk about Federal Pacific, Zinsco, and Challenger in the same breath as capacity. The insurance letter may only name the brand. The quote you get will also be about APS versus SRP and about whether the mast can survive another summer.
APS serves most of the City of Phoenix. SRP serves large East Valley areas and some Phoenix neighborhoods. Contractors who work both sides will ask for a photo of the bill. Their service-entrance hardware rules are not interchangeable.
ROC numbers are public on purpose
Arizona’s Registrar of Contractors is the cleanest license lookup of the metros on this site. RES Arizona prints ROC #147434 on the Phoenix panel page and says they replace Zinsco, Federal Pacific, and Challenger, often in a day. Oliver Electric prints ROC #229347 on a statewide cost article that names those same brands as insurance problems. Those two shops are the listings: they advertise this job and print a ROC number on their own site. 602 Electric’s cost page tells you to look for a residential electrical classification and to check roc.az.gov before you hire — useful advice, not a listing, because we did not treat that page as both bars. We did not invent any of those numbers.
What the prices actually cover
RES’s $2,500–$3,500 200-amp figure is the tightest Phoenix-specific band we found, and they say it includes permit and inspection. Oliver’s $1,800–$4,500 is a wider Arizona range. Tech Energy America’s Scottsdale table starts at $2,400–$3,800 for a panel-only 100-to-200-amp meter/main and steps up when grounding and service-entry conductors are in the scope. If three quotes land in three different bands, look at whether the mast, the grounding electrodes, and the utility ticket are included — not just the steel box.
City of Phoenix permits go through Planning and Development. Scottsdale, Tempe, Mesa, and Chandler are separate counters. A “we work the whole Valley” truck still has to pull the permit where the house sits.

Permit
Who pulls it: Permitted panel work is pulled by an Arizona ROC-licensed electrical contractor. 602 Electric’s public cost page says homeowners should look for a residential electrical classification (C-11 / R-11 territory) and verify it at roc.az.gov.
Arizona’s homeowner exemption for tiny electrical jobs does not read like a green light to replace a service panel. If the city requires a permit — and panel replacements do — plan on a licensed contractor.
Utility coordination
Arizona Public Service (APS) for most of the City of Phoenix; Salt River Project (SRP) in parts of the East Valley and some Phoenix pockets
Who disconnects: The electrician notifies APS or SRP for meter and service-entrance work. Each utility has its own service-equipment rules. Confirm the logo on the bill before the estimate.
Outage window: RES Arizona says many hazardous-panel replacements are done in a single day. We did not find an APS or SRP page that publishes a standard residential outage length.
A service-size change is a utility job as well as a city permit. A same-amp panel swap may still need a meter pull. Ask the contractor which ticket they will open.
What to hand the insurer
- Closed City of Phoenix or suburban permit
- Final inspection
- Invoice showing the ROC license number
- Photos if requested
Ask your agent for the exact list. Carriers do not publish a single national checklist.
Electricians who advertise this job
A shop is listed only if it advertises Federal Pacific, Zinsco, or insurance-driven panel replacement on its own site and prints a license number there. Trade-association locators already exist. We will not pad this list. Verify the license before you hire.
