Article 640 deals with which type of equipment?

• A. Audio Signal Processing, Amplification, and Reproduction Equipment
• B. Induction and Dielectric Heating Equipment
• C. Sensitive Electronic Equipment
• D. X-Ray Equipment

Answer: (A)

Article 640 of the National Electrical Code (NEC) specifically addresses the installation and requirements for audio signal processing, amplification, and reproduction equipment. This includes aspects such as wiring methods, grounding, and equipment ratings that ensure safety and compliance when installing and utilizing audio-related devices. The article provides important guidelines that help mitigate issues such as noise interference, safety hazards, and operational integrity of audio systems. The focus on audio signal equipment is crucial because this type of equipment often involves complex configurations and can be sensitive to electrical interference. Thus, having a dedicated article allows for more precise standards tailored to the unique requirements of audio technology, enhancing both performance and safety. Other options listed deal with different types of equipment that fall under other specific NEC articles, each with tailored regulations that address their unique operational and safety requirements. Induction heating, sensitive electronics, and X-ray equipment are governed by separate standards due to the distinct electrical characteristics, hazards, and operational protocols associated with these technologies.
