Electrical Panel Upgrade in Phoenix, AZ
Phoenix homes built before 1985 often run on a 100A or 125A panel that was sized for a swamp cooler and a single-stage AC. Adding a heat pump, a Tesla Wall Connector, or a variable-speed pool pump pushes that service past its limit on a 110°F afternoon. CheckedHomePros routes your request to AZ ROC C-11 electricians who pull the City of Phoenix permit and coordinate the APS or SRP meter cutover.
What electrical panel upgrade actually involves
Replacement of the existing service panel with a 200A Square D QO or Eaton CH load center
New grounding electrode system meeting NEC 250 as adopted by the Phoenix Electrical Code
Coordination with APS or SRP for meter pull, meter base replacement when needed, and cutover scheduling
City of Phoenix or Maricopa County permit pulled and rough plus final inspection scheduled
Optional Type 2 surge protective device added at the new panel during the same trip
Phoenix-specific things to know
- Federal Pacific Stab-Lok panels common in 1960s-1970s homes in Arcadia, Encanto-Palmcroft, and Coronado, where breakers fail to trip on overload
- Zinsco panels in 1970s Maryvale and Sunnyslope tract homes, with aluminum bus bars that corrode and arc at the breaker stab
- 100A services that drop a breaker when a heat pump, pool pump, and Level 2 charger draw at the same time during a July afternoon
- Attic-routed feeder insulation cracking after 20 summers above 150°F in unconditioned attics across the Valley
- Pitted meter bases on west-facing walls in Buckeye and Goodyear from monsoon-driven dust intrusion
