Engine-driven generators used as secondary power are considered emergency power supplies. NFPA 70 Article 700 is dedicated to emergency systems, laying out how the emergency source is connected and started, how automatic transfer switches move loads from normal to emergency power, and how the emergency circuits are wired, protected, and tested. It also covers issues like preventing backfeed to the utility, required maintenance and testing, and the qualifications of the loads that must be served by emergency power (often life-safety or critical systems). Because this topic specifically falls under emergency power requirements, Article 700 is the appropriate NEC reference. Other NEC articles focus on different topics (general wiring methods, lighting equipment, or fire alarm signaling) and don’t address the emergency power specifics.
