NFPA has been working on a series of videos to help explain the significant changes to the 2017 edition of NFPA 70: National Electrical Code that impacts the electrical industry as a whole, as well as the work you do every day. We’re pleased to see so many of you are taking the opportunity to view the videos and ask questions on our Xchange platform.


Please join me for the next video in the series. In this one, I talk through the significant changes that impact limited energy circuits and communications systems, most notably in Chapters 7 and 8 of the NEC. These changes include:
•    Revisions on the use of unsupported lengths of power-limited tray cables
•    A new condition allowing metal masts and supporting structures for antennae to be protected by a building or structure lightning protection system instead of direct connection to a grounding electrode
•    New requirements covering the ampacity of signaling, data and communications cables that also provide power to connected devices in order to keep pace with new power over the Ethernet (PoE) technology


… plus other impactful changes from the 2017 edition that you absolutely need to know.
The following is a video preview:
