Which of the following articles covers safety procedures for electrical installations?

The correct choice is Article 110, which covers general requirements for electrical installations, including safety procedures. This article addresses the essential aspects of safety in electrical installations, such as working conditions, access to equipment, and installation practices that ensure safe operation and maintenance of electrical systems.

Article 110 establishes the foundational requirements for ensuring the safety of the installation and the personnel involved. It emphasizes the need for safe work practices, proper access to electrical equipment, and guidelines to prevent electrical hazards. A thorough understanding of these procedures is essential for any electrical contractor as it helps minimize risks and comply with safety regulations.

While other articles, such as Article 225, Article 230, and Article 408, focus on specific types of installations or equipment, they do not encompass the broad range of safety procedures applicable to general electrical installations that Article 110 covers.
