Electrical Panel Upgrade FAQ — Phoenix, AZ

Frequently Asked Questions: Electrical Panel Upgrades in Phoenix, AZ

How much does a 200-amp panel upgrade cost in Phoenix?

Most projects land in the $2,400-$4,800 range when no major utility-side reconstruction is required.

Do I need a permit in Phoenix?

Yes. Panel upgrades require permitting and inspection through City of Phoenix Planning & Development Department (https://www.phoenix.gov/pdd).

How long does a panel upgrade take?

The on-site electrical work is usually completed in one day. Full timeline is typically 1-4 weeks depending on permit review and APS / SRP scheduling.

Should I replace a Federal Pacific or Zinsco panel immediately?

Yes. These legacy panels have documented safety concerns and are commonly flagged by inspectors and insurers. Replacement is strongly recommended.

Can I add an EV charger without upgrading the panel?

Sometimes, but many homes require panel capacity upgrades first. A licensed electrician should perform a load calculation before adding a 240V EV circuit.

How do I verify contractor licensing?

Verify licensing through Arizona Registrar of Contractors (ROC) (https://roc.az.gov/) and confirm the contractor pulls permits in their own license name.
