A hospital's backup generator and a house's aren't the same to the NEC.
In this lesson: Article 700 Emergency (life safety, 10-second transfer), 701 Legally Required Standby (code-mandated but not life safety, 60-second transfer), 702 Optional Standby (owner's choice, no required time), the fire pump exam trap (they're Article 695, not 700), wiring separation, automatic transfer, generator run-time and placement, and how to classify a real system in seconds.
Based on the 2023 NEC (Articles 700, 701, 702, 695).
