WebAs a regulatory requirement, selective coordination has evolved over the past 20 years, most significantly over the past decade. Selective coordination was first required for elevator circuits in the 1993 edition of the NEC. During the 2005 NEC revision cycle, the Code Making Panel elevated selective coordination from a design consideration to a WebType 1 and Type 2 coordination is a definition that applies to motor starters, set out in the IEC standard 60947-4-1. The coordination level relates to the level of resilience and protection in the event of a high current short-circuit fault. The differences between the two types can be summarised as follows.
