The National Fire Protection Association issued Tentative Interim Amendments (TIAs) to the 2014 NEC on August 4, 2016, which was after the 2016 CEC was adopted and published July 1, 2016. Tentative Interim Amendments (TIAs) are designed to address critical problems within an NFPA standard that requires prompt action before the next edition of the NFPA standard.
