How does North Carolina adopt the NEC?
North Carolina enforces the 2020 NEC with state amendments (2020 NC Electrical Code, effective November 1, 2021) in every building except one- and two-family dwellings, which section 10.1 of those amendments sends to the 2017 NC Electrical Code (2017 NEC with 2017 NC amendments). The State Fire Marshal applies that to townhouses up to three stories and to accessory structures such as detached garages, pools and docks; apartments, condominiums and triplexes follow the 2020 code (OSFM interpretation, 2021). The 2020 amendments change 32 NEC sections; among them they delete 210.8(F) (GFCI for outdoor outlets), 230.67 (surge protection) and 406.4(D)(4) (AFCI for replacement receptacles) and add GFCI exceptions to 210.8(A). For one- and two-family dwellings, the 2017 amendments limit AFCI (210.12(A)) to a room list without kitchens and laundry areas and delete the 210.8(D) dishwasher GFCI requirement.
What are North Carolina's amendments to the NEC?
210.12(A): One- and two-family dwellings (2017 NC Electrical Code, 2017 NEC numbering): AFCI is required for 15- and 20-ampere branch circuits supplying family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways and similar areas; kitchens and laundry areas are not on North Carolina's list. The 2020 NC Electrical Code does not amend 210.12(A).
210.12(D): Modified, replaced or extended branch-circuit wiring in an AFCI area needs AFCI protection by an allowed means, including an outlet branch-circuit AFCI at the first receptacle of the existing circuit, except an extension of 50 feet or less that adds no outlets or devices (2020 NC Electrical Code; 2017 code for one- and two-family dwellings).
406.4(D)(4): The 2020 NC Electrical Code deletes the AFCI requirement for replacement receptacles. For one- and two-family dwellings the 2017 NC code (amended January 1, 2021) requires a replacement receptacle in an area listed in 210.12(A) or (B) to be an outlet branch-circuit AFCI receptacle or AFCI-protected, with exceptions.
210.8: 2020 NC Electrical Code: 210.8(F) (outdoor outlets) is deleted; 210.8(A) exempts a 250-volt receptacle installed for a dryer, range, oven or similar cooking appliance, and adds exceptions for a garage-door-opener receptacle more than 8 feet up, a dedicated sewage-lift-pump receptacle and a fire or burglar alarm receptacle in an unfinished basement. 2017 NC code (one- and two-family dwellings): GFCI covers 125-volt 15- and 20-ampere receptacles, and the 210.8(D) dishwasher requirement is deleted.
230.67: Deleted: the 2020 NC Electrical Code does not require surge protection at dwelling services.
250.142(B): One- and two-family dwellings: where a main disconnect is relocated or added and the old service conductors become a feeder, the existing panelboard may stay grounded through the neutral if it has no equipment grounding conductor, replacing the conductors is impractical, all grounding electrode conductors are removed from it and the neutrals are insulated (2017 NC Electrical Code 250.142(B) Exception No. 5; 2020 code Exception No. 4).
Who issues electrical permits in North Carolina?
Local inspection departments (city, county or joint) issue electrical permits, inspect and issue a certificate of compliance at final inspection (G.S. 160D-1102, 160D-1104, 160D-1110, 160D-1116); the state building code applies throughout the state (G.S. 143-138(e)). In one- and two-family dwellings, a licensed electrical contractor needs no permit to replace fixtures, receptacles or switches with ones of the same voltage and the same or lower amperage, or to reconnect a like replacement electric water heater (G.S. 160D-1110(a)(4)).
Who licenses electricians in North Carolina?
The NC State Board of Examiners of Electrical Contractors licenses every person or firm in the business of electrical contracting (G.S. 87-39, 87-43). Each licensee needs a qualified individual who has passed the Board's exam on duty at each place of business; licenses are Limited or Intermediate (with project-value limits), Unlimited, or special restricted classes such as the single-family detached dwelling license (G.S. 87-43.3, 87-43.4). An employee of a licensee needs no license for that work (G.S. 87-43.1), and North Carolina's licensing law creates no journeyman license. Licensing board: North Carolina State Board of Examiners of Electrical Contractors.

Is North Carolina moving to a newer NEC edition?
The Building Code Council adopted the 2023 NC Electrical Code on December 12, 2023, for January 1, 2025, as part of the 2024 NC State Building Code; S.L. 2024-57 moved it to July 1, 2025, and S.L. 2025-2, Section 5.12 set it at 12 months after the first day of the month following the State Fire Marshal's certification that the code is published and distributed and the Residential Code Council is fully constituted. As of September 2026 OSFM lists the 2023 code as delayed indefinitely and the Residential Code Council's members as not yet determined, so the 2020 code, and the 2017 code for one- and two-family dwellings, remain in force.
Is North Carolina on NEC 2026?
No. NEC 2026 is the newest edition; the one current in North Carolina is NEC 2020, two editions older. NFPA publishes a new edition every three years and each state adopts on its own schedule.
