The National Fire Protection Association (NFPA) recently released a proposed Tentative Interim Amendment (TIA) to the 2023 Edition of the National Electrical Code (NEC). The TIA was submitted by Michael Savage, Sr., Marion County Building Safety, and has a comment closing date of September 28, 2023.
TIA Log No.: 1752
Reference: 517.30(B)(3)(a)
1. Revise section 517.30(B)(3)(a) to read as follows:
517.30(B)(3) Fuel Cell Systems. Fuel cell systems shall be permitted to serve as the alternate power source for all or part of an EES. [99:6.7.1.5.1]
(a) Installation of fuel cells shall comply with the requirements in Parts I through VI VII of Article 692 for 1000 volts or less and Part VIII for over 1000 volts.
Substantiation: In the 2017 revision cycle, CMP 4 deleted Part VIII of Art. 692, then during the 2020 revision cycle, Art. 692 was reduced to six parts. There are no references in the current language to voltages, either 1000V or more, or 1000V or less, therefore the incorrect references need to be remedied through the TIA process.
Emergency Nature: The standard contains an error or an omission that was overlooked during the regular revision process.
In the 2017 and 2020 NEC code revision cycles Part VII and VIII were removed, with the 2020 revision cycle reducing a total of six parts, this TIA seeks to correct the error of identifying the parts that were removed during the previous revisions’ cycles.
