TIA Related to the Wiring of Emergency Systems Issued

Aug. 16, 2017
Tentative Interim Amendment needs input.

Tentative Interim Amendment (TIA) Log #1293 to NFPA 70, National Electrical Code, 2017 edition, revises Sec. 700.10(D). The comment closing date on this TIA is Sept. 14, 2017.

As noted in the substantiation section of this TIA:

“Article 700.10(D)(3) “Health care occupancies where persons are not capable of self preservation” conflicts with the current (2015) version of NFPA 99.”

As outlined in a portion of the Emergency Nature section of this TIA:

“The standard contains a conflict within the NFPA Standard or within another NFPA Standard. The conflict between NFPA documents 70, 700.10 (D) (3), and 99, 6.5.2.2.1.5, may result in AHJs being unable to determine which of the code statements takes precedence.”

You can view the full text of the TIA on the NFPA website.

Note: A TIA is tentative because it has not been processed through the entire standards-making procedures. It is interim because it is effective only between editions of the standard. A TIA automatically becomes a public input of the proponent for the next edition of the standard; as such, it then is subject to all of the procedures of the standards-making process.
