Tips
- Confirm your electrician holds a current Natrona County electrical license (Contractor/Master/Journeyman/Apprentice, or Low Voltage/Limited class) — Natrona County runs its OWN electrical licensing program separate from the Wyoming State Fire Marshal's statewide program used by most other unincorporated WY counties.
- This differs from many other Wyoming counties (e.g. unincorporated Albany, Sweetwater, Sheridan, Uinta, Fremont) where electrical is handled by the state — in Natrona County, always use the COUNTY'S OWN application and licensing, not wsfm.wyo.gov.
- Solar/PV installation is a listed 'Nature of Project' option directly on the electrical permit application — no separate standalone solar electrical form exists; use this Electrical Permit Application for the electrical interconnection portion of a solar project.
