Article 702 of the NEC deals with which systems?

The reason why the answer pertains to Optional Standby Systems is that Article 702 of the NEC specifically focuses on the installation and requirements for these systems. Optional Standby Systems are designed to provide power to specific systems or equipment in the event of a power outage, ensuring operational continuity for critical functions. This article outlines the necessary provisions for the design, installation, and maintenance of these systems, which can include generators and other sources of backup power.

Understanding Optional Standby Systems is crucial for electrical contractors and engineers because they facilitate the safe and efficient operation of equipment during emergencies, without being classified as life safety or critical systems like Emergency Systems found in Article 700. Therefore, a clear grasp of Article 702 is essential for compliance with safety standards and ensuring that these systems work effectively when needed.
