Circuit breaker protection coordination
WebMay 9, 2002 · All the wiring in a house runs through a central circuit breaker panel (or fuse box panel), usually in the basement or a closet. A typical central panel includes about a dozen circuit breaker switches … WebThe Selective Coordination Analysis Tool provides you with the ability to select combinations of Circuit Breakers that provide total selective coordination (some in the industry refer to this as selectivity down to 0.01 seconds). The scope of this tool encompasses only breaker-to-breaker short circuit selective coordination.
