What is selectivity? The electrical design industry has historically required electrical system circuit breaker selections and settings be validated with ashort circuit and coordination studyperformed by a licensed engineer. These studies assure that circuit breakers are capable of interrupting the available current and would operate “selectively”. Traditionally,“selectivity”in a low voltage electrical system meant that the long time and short time portions oftime-current curves (TCCs)would be selective, i.e. the circuit breaker closest to the fault would trip first, maximizing the amount of the electrical distribution system left in service In most cases, thecircuit breaker instantaneous ov...
