                Selective Coordination


                Smart Mission Critical Solutions and Expert Guidance for Meeting Codes and Standards


                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. In a selectively coordinated system, only the circuit breaker that directly supplies the overloaded/faulted part of the system will trip, limiting the service interruption to only the circuit experiencing the problem and not shutting down the larger portion of the power system.

                Achieving Selective Coordination

                Designing a coordinated electrical distribution system requires knowledge about the application and circuit breakers being specified. Considering selective coordination early in the design phase makes the process easier and more cost-effective. Conducting a comprehensive short-circuit current study and an overcurrent coordination study of the electrical power system is the only true method of achieving selective coordination and equipment protection.

                To selectively coordinate branch circuit faster and easier, use the Selective Coordination Analysis Tool.
