Florida uses a state-amended version of the NEC. Whether you are sizing a service entrance in Florida, calculating voltage drop on a long feeder run, or verifying conduit fill for a commercial panel installation, SparkShift's 40+ NEC calculators run in any browser and require no sign-up.
State note: Florida uses the Florida Building Code — Electrical (FBC-E), based on NEC 2020. Chapter 69A-60, Florida Administrative Code, governs electrical inspections and installations. Hurricane-prone area rules add wiring protection requirements beyond the base NEC. Pool and spa installations carry Florida-specific Article 680 amendments.
Licensing in Florida is administered by the Florida Department of Business and Professional Regulation (DBPR). All calculations on SparkShift default to NEC provisions; always verify against the edition your AHJ enforces and any Florida-specific amendments.

Yes — virtually all Florida jurisdictions require an electrical permit and inspection for service entrance upgrades, panel replacements, and load center relocations. The permit is pulled through your local AHJ, which may be a city building department, county, or state authority. The specific process varies by municipality; contact the Florida Department of Business and Professional Regulation (DBPR) or your local AHJ for requirements.
