Which article addresses systems related to industrial machinery?

Article 670 of the National Electrical Code (NEC) specifically deals with the requirements for industrial machinery. This article outlines the safety provisions, wiring methods, motor control, and other electrical installations associated with various forms of industrial machinery. The focus of Article 670 is to ensure safe operation and prevent hazards that could arise from the unique characteristics of industrial equipment, which often operates under different conditions compared to standard residential or commercial electrical systems.

In contrast, other articles listed focus on different subjects: for instance, Article 680 pertains to swimming pools and similar installations, Article 675 involves specific requirements for the installation of electrical equipment in hazardous locations, and Article 692 discusses renewable energy systems. Understanding the purpose and scope of each article helps in effectively applying the NEC standards to various electrical installations, particularly in an industrial setting where safety and adherence to the code are critical.
