Is it true or false that Article 110 only applies to electrical installations covered by chapters 1 through 4?

The statement is false because Article 110 of the National Electrical Code (NEC) pertains to general requirements for electrical installations, including those not limited to just the specific chapters. Article 110 sets forth standards for the installation, operation, and maintenance of electrical equipment and installations but applies broadly across various types of electrical systems, extending beyond just chapters 1 through 4.

It covers essential aspects that are relevant to all electrical installations, ensuring they adhere to safety and operational guidelines regardless of the specific application or setting. This includes commercial, industrial, and residential environments, thus highlighting the far-reaching applicability of the article in promoting safety across various settings.
