Code News Update


As noted on the NFPA website, three Tentative Interim Amendments (TIAs) have recently been issued for the 2011 NEC. All three had an issue date of October 19 and an effective date of November 8, 2011. The TIAs were related to these sections of the Code:

  • 625.13 Electric Vehicle Supply Equipment Connection
  • 625.14 Rating
  • 230.44(5)
You can read the full details of each TIA by clicking on the items listed under the heading Tentative Interim Amendment on the NFPA 70 landing page of 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 proposal 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.
