NFPA 110-2025 Standard for Emergency and Standby Power Systems
Chapter 6: Transfer switch equipment – NFPA 110-2025 Standard for Emergency and Standby Power Systems

NFPA 110-2025 Standard for Emergency and Standby Power Systems 6.2.14-6.2.16: 6.2.14 to 6.2.16 Motor load transfer, neutral isolation and nonautomatic switches

Provisions limit inrush from transferring motor loads where it could damage equipment or trip devices; neutral continuity, transfer and isolation are provided where the sources are separately grounded for ground-fault sensing; and nonautomatic switches are mechanically held, operated manually or by remote electrical control, interlocked against paralleling, and show their position.
