What type of systems does Article 685 encompass?

Article 685 of the National Electrical Code (NEC) specifically addresses Integrated Electrical Systems. These systems are designed to consist of a combination of electrical components that work together to serve a particular purpose or function, which may encompass various energy generation, distribution, or conversion methods.

This article provides the standards for the safe installation and maintenance of these systems, ensuring that they operate efficiently and do not pose safety hazards. Understanding the scope of Integrated Electrical Systems under Article 685 is crucial for electrical professionals because it helps ensure compliance with safety standards, proper integration of components, and effective performance of the overall system.

In contrast, other options such as fuel cell systems, solar photovoltaic systems, and fire pumps are covered under different articles in the NEC, which focus specifically on their distinct requirements and safety considerations. Recognizing the specific focus of Article 685 highlights the importance of adhering to the regulations that pertain to the integration and operation of multiple electrical components.
