NFPA 70, the National Electrical Code, has just had an errata released modifying the new 2011 Edition. It is the second errata released for this edition of the NEC so far. Additionally, there have been four Tentative Interim Amendments released which also impact the use of the document.
Errata are numbered using first the Code number, then the year of the edition and finally the numeric identifier. So the first Errata for NFPA 70 was Errata 70-11-1, from 4/8/2011. This errata made pen-and-ink changes to 23 different pages. The new second Errata is 70-11-2, from 1/24/2012, with changes for 8 different pages.
Tentative Interim Amendments (TIA’s) follow a similar numbering scheme. 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 for the next edition of the standard.
TIA 11-1 for the NEC, released on 3/1/2011, makes 2 exceptions for section 680.42(B). TIA’s 11-2, 11-3, and 11-4 were all released 10/19/2011. TIA 11-2 modifies section 625.13 on Electric Vehicle Supply Equipment Connection. TIA 11-3 impacts section 625.14, Rating for Electric vehicle supply equipment. And TIA 11-4 is a change for section 230.44(5).
