What You'll Learn
The National Electrical Code (NEC)
The NEC is updated every three years by experts and engineers from the National Fire Protection Association (NFPA) to address new technologies and reflect the latest safety research. The NEC contains two types of rules: mandatory and permissive. Mandatory rules use terms like "shall" or "shall not" and indicate requirements that must be followed. For example, "Electrical panels shall have a clear working space 36 inches wide and 30 inches deep in front of them." On the other hand, permissive rules use the phrasing "shall be permitted," indicating options that are allowed but not required. For instance, "In unfinished basements, exposed Romex wiring shall be permitted."
The North Carolina State Electrical Code is based on the NEC but also includes state-specific amendments. While there were no transition periods between various editions of the Electrical Code in the past, the state now provides dates for when specific editions of the NEC were in effect, along with links to any corresponding electrical amendments. The NFPA website provides access to all editions of the NEC, although users must create an account to view the codes. The 2015 NC Existing Building Code, which was effective from March 1, 2015, through December 31, 2018, has now expired, and the NC Rehabilitation Code is effective until 2025.
It is important to note that while the NEC provides guidelines and standards for safe electrical practices, it is not a substitute for local or state-specific electrical codes and regulations. Electricians and engineers must refer to the relevant authorities and governing bodies in their respective areas to ensure compliance with the applicable codes and any updates or amendments. Adhering to the NEC helps reduce fires, shock hazards, and other electrical risks, making it safer for both electricians and residents in buildings with electrical systems.

North Carolina State Electrical Code Amendments
The North Carolina State Electrical Code consists of an adapted version of the National Electrical Code (NEC) supplemented by North Carolina Amendments. The Electrical Code is updated periodically, with the 2023 State Electrical Code (2023 NEC with State Amendments) being the most recent version as of February 2024. This code was accepted by the Building Code Council and the Rules Review Commission.
The state's electrical code typically undergoes amendments every few years, with the previous update being the 2020 State Electrical Code (2020 NEC with State Amendments), which was accepted in 2021. The 2020 version included amendments such as the One- and Two-Family Exception Scope (Sections 10.1 and 10.2) and amendments to Section 210.11(C).
Prior to that, the 2017 Electrical Code was effective from June 12, 2018, through June 11, 2018, with no transition periods between editions. The 2014 Electrical Code was in effect from April 1, 2016, to June 11, 2018. The 2011 Electrical Code was effective from July 3, 2011, to April 1, 2016.
In addition to the electrical code, North Carolina also has a range of other building codes, including the Existing Building Code, Rehabilitation Code, Accessibility Code, and Fuel Gas Code, which are also subject to periodic amendments and updates. These codes are promulgated by the North Carolina Building Code Council (BCC) and interpreted and enforced by the Engineering and Codes Section.

North Carolina Accessibility Code
The North Carolina Accessibility Code is a set of regulations that ensure sites, buildings, structures, facilities, and spaces are accessible to individuals with disabilities. The code is part of the North Carolina Building Code, which is promulgated by the North Carolina Building Code Council (BCC) and interpreted and enforced by the Engineering and Codes Section.
The Accessibility Code includes requirements for accessible routes, units, circulation paths, public entrances, and more. For example, according to the 2012 North Carolina Building Code, accessible routes must have a clear width of at least 48 inches (1220 mm). The code also specifies when certain areas are exempt from these requirements, such as detached single-family dwellings, religious spaces, and areas accessed only by ladders or catwalks.
The North Carolina Rehab Code is another important component of the state's accessibility regulations. This code is specifically designed for existing buildings and provides guidelines for repair, renovation, alteration, and reconstruction. It aims to make it easier and more affordable to rehabilitate older structures, including historic buildings, to meet modern safety and accessibility standards.
To ensure digital accessibility, North Carolina state agencies are encouraged to follow the North Carolina Accessibility and Usability Standard, which outlines best practices for creating accessible digital content.
The specific requirements of the North Carolina Accessibility Code can vary depending on the year of its implementation and any amendments made by the BCC. For example, the 2009 NC Accessibility Code includes the 1999 NC Accessibility Code with the 2002 NC Amendments, while the 2018 NC Codes include the 2018 NC Ad-Hoc Committee amendments adopted by the Building Code Council. It is important to refer to the official sources for the most up-to-date and accurate information on the current accessibility requirements in North Carolina.
