Stay up to code with the updated 2017 National Electrical Safety Code (NESC)
This Code covers basic provisions for safeguarding of persons from hazards arising from the installation, operation, or maintenance of (1) conductors and equipment in electric supply stations, and (2) overhead and underground electric supply and communication lines. It also includes work rules for the construction, maintenance, and operation of electric supply and communication lines and equipment. The standard is applicable to the systems and equipment operated by utilities, or similar systems and equipment, of an industrial establishment or complex under the control of qualified persons. This standard consists of the introduction, definitions, grounding rules, list of referenced and bibliographic documents, and Parts 1, 2, 3, and 4 of the 2017 Edition of the National Electrical Safety Code.
- Scope, application, and definitions have been revised for improved clarity, particularly with respect to whether the NESC or the National Electrical Code applies in certain situations.
- Grounding rules added specificity to the methods used to help achieve effective grounding connections.
- Electrical supply stations rules added options for improved protection of energized parts from interference by activities outside the stations and rules for guarding inside the stations.
- Underground rules revised the inspection rules and clarified requirements for direct-buried cables and conduits not part of a conduit system.
- Work rules added options for determining appropriate arc ratings for apparel to be worn while working on energized lines.
- Minimum approach distances (MADs) were revised to meet the requirements of IEEE 516(TM)-2009, and specification for the location of employee protective grounds was revised.
