What is the NESC 2023 National Electrical Safety Code?
New code in effect as of 1 February 2023 and is available for access on IEEE Xplore. Produced exclusively by IEEE, the National Electrical Safety Code (NESC) specifies best practices for the safety of electric supply and communication utility systems at both public and private utilities.
What is the NESC National Electrical Safety Code?
Published exclusively by IEEE and updated every five years to keep the Code up-to-date with changes in the industry and technology, the National Electrical Safety Code® (NESC®) sets the ground rules and guidelines for practical safeguarding of utility workers and the public during the installation, operation, and ...What is the latest version of the NESC? - 2023 edition
Course Overview. The 2023 edition of the National Electrical Safety Code (NESC) will be published in August 2022 by the Institute of Electrical and Electronics Engineers (IEEE). The NESC is the national standard for safety in the design, construction, operation, and maintenance of electric and communication systemsWhat is the difference between NESC and NFPA 70E?
The primary difference is that the NFPA 70E table values are based on calculations, while the NESC table values are a combination of arc energy levels from calculations and results from actual test results performed in a utility test lab.What is the purpose of the NESC?
In addition to emphasis placed on the need for appropriate protective clothing for workers, the NESC provides guidance and rules for specific situations such as the effective grounding of circuits, and maintaining minimum safe clearances between conductors and the ground or nearby buildings.What are the four main parts of the NESC?
Following the general sections are four main parts including: rules for electric supply stations (Part 1), rules for overhead lines for clearances and strength and loading (Part 2), rules for underground lines, (Part 3), and work rules (Part 4).Does OSHA follow NEC code?
The OSHA electrical standards were based on the National Fire Protection Association's standard NFPA 70E, Electrical Safety Requirements for Employee Workplaces, and the NFPA 70 Committee derived Part I of their document from the 1978 edition of the National Electrical Code (NEC).

Full Description
Scope
The NESC covers:
1. Supply and communication facilities (including metering) and associated work practices employed by a public or private electric supply, communications, railway, trolley, street and area lighting, traffic signal (or other signal), irrigation district or other community owned utility, or a similar utility in the exercise of its function as a utility.
2. The generation, transmission, and distribution of electricity, lumens, communication signals, and communication data through public and private utility systems that are installed and maintained under the exclusive control of utilities or their authorized representatives.
3. Utility facilities and functions of utilities that either (a) generate energy by conversion from some other form of energy such as, but not limited to, fossil fuel, chemical, electrochemical, nuclear, solar, mechanical, wind or hydraulic or communication signals, or accept energy or communication signals from another entity, or (b) provide that energy or communication signals through a delivery point to another entity.
4. Street and area lights that provide a supply of lumens where these facilities are supplied from the line side of the service point by underground or overhead conductors maintained and/or installed under the exclusive control of utilities (including their authorized contractors or other qualified persons).
5. Utility facilities and functions on the line side of the service point supplied by underground or overhead conductors maintained and/or installed under exclusive control of utilities located on public or private property in accordance with legally established easements or rights-of-way, contracts, other agreements (written or by conditions of service), or as authorized by a regulating or controlling body.
6. Wiring within a supply station or in an underground facility that is (a) installed in accordance with Part 1 or Part 3 of this Code and maintained under the exclusive control of utilities and (b) necessary for the operation of the supply station or underground facility.
7. Utility facilities installed, maintained, and controlled by utilities on surface or underground mine sites, including overhead or underground distribution systems providing service up to buildings or outdoor equipment locations on the line side of the service point.
8. Similar systems to those listed above that are under the exclusive control of qualified persons and authorized by a regulating or controlling body, including those associated with an industrial complex or utility interactive system.
Purpose.
The purpose of the NESC is the practical safeguarding of persons during the installation, operation, and maintenance of electric supply and communication facilities, under specified conditions. NESC rules contain the basic provisions, under specified conditions, that are considered necessary for the safeguarding of the public and utility workers (employees and contractors)..
