2 2016 NFPA CAMs 43 NITMAM (Notice Intent To Make a Motion) Certified Amending Motions (CAMs) submitted for NFPA CAMs passed the Floor Vote The New Process of Inputs/Comments PI/PC led to First Drafts and Second Drafts: Rules and Regulations limit new language during this process due to lack of public review CMPs are restricted to the actions of the PCs and PIs. There may be PI and PC submitted by the Panels. TIAs are automatically submitted as inputs.

3 CAM Results of interest Failed - AFCI 2014 language remains (Results - AFCI System remains and no expansion ) (F) Passed - There was new language restricting the number of Feeders to sizes 1/0 or larger (Results - Taken out, all sizes are allowed to be considered ) (D) Passed - Language to require Service Disconnects Outside (removed requirement, previous language remains) Passed - requirement for increasing wire EGC was limited to Voltage Drop only when increasing ungrounded Conductors (all considerations, i.e. correction factors will require EGC to be increased)

4 CAM Results of interest (cont) Failed - Cablebus ampacities are now subject to ampacity tables and not Free Air tables ( Second Draft remains as-is) Passed - Tray Cable allowed in C1-D1 locations (removed) purview problems? 520.4(5) Cords on the Floor, language would have allowed BC and Feeder cables (art 400) to be on the ground (Removed language) Transcription correction All information on the meeting results on the Next Edition tab for NFPA 70
