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.
