They cover similar systems under the control of qualified persons, such as those associated with an industrial complex or utility interactive system. B. The NESC covers utility facilities and functions up to the service point.NOTE: The National Electrical Code (NEC), NFPA 70-1999 covers utilization wiring requirements beyond the service point.C. NESC rules cover street and area lights (supplied by underground or overhead conductors) under the exclusive control of utilities (including their authorized contractors) or other qualified persons (such as those associated with an industrial complex).NOTE: Luminaries not under such exclusive control are governed by the requirements of the NEC.D. NESC rules do not cover installations in mines, ships, railway rolling equipment, aircraft, or automotive equipment, or utilization wiring except as covered in Parts 1 and 3.Purpose
The purpose of these rules is the practical safeguarding of persons during the installation, operation, or maintenance of electric supply and communication lines and associated equipment.These rules contain the basic provisions that are considered necessary for the safety of employeesand the public under the specified conditions.
