Why Selective Coordination is Mandatory – Presentation

 

ImageThere are now requirements for mandatory selective coordination in 4 different Articles in the NEC. The first, in Article 620, was added in 1993 for elevator circuits.  The second and third, in Articles 700 and 701, for emergency systems and legally required standby systems, were added in the 2005 NEC.  The most recent, in Article 708, for Critical Operations Power Systems, was added in the 2008 NEC.  Click here to review a presentation on the reasons that selective coordination is required for life-safety-related systems in the NEC by Cooper Bussman.

  • I would have liked to view the presentation on selective coordintation, but it is apparently presented in an unusual formate (Articulate) that I don't have and have never heard of. I went to the Articulate site, but there is apparently no free viewer, or I couldn't locate one. I'd recommend limiting presentations to more standard formats in the future if possible.
