I have the 2014 book which has many errors. Errata is posted on the NFPA website. We are working under the 2014 code with revisions here in Massachusetts since January 1st...biggest moan and groan around here is all the AFCI protection added for dwellings. AFCI everything in the kitchen...DW, DP, ref, micro, even the oil burner if it is controlled by a device in the kitchen.
