Selective Coordination Requirements, Solutions, Tips and Tricks

The electrical power industry has been struggling to address the recently added code requirements of selective coordination that apply to Emergency, Legally Required, Elevator, Fire Pumps, and COPS systems. Selective coordination is essential for proper fault isolation of these important systems. Old rules of thumb are no longer valid, and it is critical for design engineers to understand the implications of these requirements and define new solutions and rules of thumb to prevent major re-design to comply with code. This webinar, given by Joe Dietrich, P.E. and Joe Kerfoot, P.E., electrical engineers at Rosendin Electric, explains valuable insights and provides guidance for design engineers to help them re-imagine essential system design practices.
