Article 110.7 pertains to which aspect of electrical installations?

Article 110.7 of the National Electrical Code (NEC) focuses specifically on the examination, identification, and use of electrical equipment. This article emphasizes the importance of ensuring that all electrical equipment is suitable for the intended application and has been properly examined for safety and performance. It sets the groundwork for identifying equipment by its ratings and marking, ensuring that installers and users can effectively and safely use electrical devices.

By detailing the significance of examining and identifying electrical equipment before installation or use, Article 110.7 helps prevent misuse, enhances system reliability, and contributes to overall safety in electrical installations. Understanding this aspect is crucial for compliance with the NEC and for ensuring that electrical systems operate as intended while minimizing risks.

The focus of the other choices lies in areas that are addressed elsewhere in the NEC or require different sets of codes and standards: installation techniques relate more to the practical means of putting equipment in place, energy consumption measurement pertains to efficiency and usage rather than safety, and safety equipment requirements are governed by other specific sections of the code.
