NFPA 79: Electrical Standard for Industrial

The NFPA 79 (2018 Edition) is the key U.S. electrical safety standard for industrial machinery, covering electrical/electronic components operating under 1000V, focusing on operator/equipment protection, and harmonizing with international standards like IEC 60204-1, with major updates in this edition including mandatory Surge Protective Devices (SPDs) for safety circuits. Published in late 2017, it’s a vital document for manufacturers and users, detailing requirements for wiring, grounding, color-coding (e.g., black for AC power, red for AC control), and safety functions to prevent electrical hazards in manufacturing environments.
