Section 700.12 – Add an Informational Note after Section 700.12(D)(2)(d) to read as follows:
Informational Note: Operational requirements in other codes and regulations may specify fuel supplies that support longer durations of operation for certain occupancies. See Articles 517 and 708.
Section 700.12 – Add a new Section 700.12(D)(6) to read as follows:
(6) Grounding of Temporary Generators Connected to Building Wiring System. Temporary generators used to supply building wiring systems shall comply with 250.35(A) for separately derived systems or 250.35(B) for non-separately derived systems.

(G) Fuel Cell System. Fuel cell systems shall be permitted to be used as a source of power for emergency systems in Group R-2 occupancies and shall be of suitable rating and capacity to supply and maintain the load for not less than 6 hours of full-demand operation. Installation of a fuel cell system shall meet the requirements of Parts II through VIII of Article 692. Where a single fuel cell system serves as the normal supply for the building or group of buildings concerned, it shall not serve as the sole source of power for the emergency standby system.
Section 700.12 – Revise Section 700.12(H) to read as follows:
(H) DC Microgrid Systems. DC Microgrid systems shall not be permitted unless approved by the AHJ. The system shall be capable of being isolated from all non-emergency sources.
DC microgrid systems used as a source of power for emergency systems shall be of sufficient rating and capacity to supply and maintain the total emergency load for not less than 6 hours of full demand operation.
Where a DC microgrid system source serves as the normal supply for the building or group of buildings concerned, it shall not serve as the sole source of power for the emergency standby system.
