      SELECTIVE COORDINATION SOLUTIONS

      Certain electrical power system designs need to ensure the selection and setting of protective devices cause the smallest possible portion of the system to be de-energized due to an abnormal condition.

        Selectivity Guidelines For Square D Panelboards

        The natural advantages of circuit breakers make them the logical choice for overcurrent protection. This guide is intended to facilitate the design of selectively coordinated systems when using Square D™ I-Line™, NF and
        NQ panelboards.

        Energy-Based Tripping and Its Affects on Selective Coordination

        This paper examines selective coordination methods for circuit breakers, beyond the traditional plotting of time-current curves (TCCs) alone, for high fault currents. Specifically, an energy-based circuit breaker tripping system, which can provide improved selectivity, series rated combinations, and favorable arc flash performance, is presented and examined.

        Selective Coordination versus Arc Flash Requirements

        High system performance achieved through selective coordination, required in changes to the National Electric Code® results in increased arc flash energy. This conflict between selective coordination and arc flash isexplained in this paper through real world examples.
