This article gives you a clear, practical framework for navigating NEC Article 250, NFPA 780, NFPA 77, IEC 62305-3, IEEE Std 142, and related standards, with special focus on the bonding and documentation requirements that trip up even experienced engineers. Static discharge: Metal doors can build up static charge, especially in high-voltage environments. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. During the manufacturing process, metal enclosures typically have fixed points welded to the base plate or side walls. Note to paragraph (a): This section covers grounding of transmission and distribution lines and equipment when this subpart requires protective grounding and whenever the employer chooses to ground such lines and equipment for the protection of employees.
