What are the NFPA requirements for emergency and standby power systems?

International Building Code (IBC): Following IBC 2024 Chapter 27 Section 2702.1.3, emergency or standby power systems must be installed following the guidelines outlined in the International Fire Code IFC), NFPA 70: National Electrical Code (NEC) and NFPA 111: Standard on Stored Electrical Energy Emergency and Standby Power Systems.

How many opening releases should a circuit breaker have?

1.3.6 300 kV and 420 kV circuit-breakers shall be provided with two opening releases per operating mechanism. The opening releases shall be arranged for supply from independent battery systems and shall have segregated circuits such that failure of one device in a circuit does not prevent opening of the circuit-breaker.

When should a circuit breaker be charged and discharged?

1.2.9 Means shall be provided to allow the stored energy system to be charged and discharged when the circuit-breaker is either closed or open without causing operation of, or damage to, the circuit-breaker. This requirement is waived for springs connected directly to moving contacts, such as opening springs.
