8. Add the distance of your answer to the position of the first mark and make the second mark. In this case, 6 inches plus another 6 inches places the second mark at 12 inches.
Breaking capacity or interrupting rating is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration.reaking capacity current corresponds to a voltage, so an electrical apparatus may have more than one breaking capacity current, according to the voltage.
Recently, a SF. 6 generator circuit-. breaker with a rated current of 24,000 A (naturally cooled, higher rated currents with forced. air cooling) and a short-circuit breaking current of 160 kA at a maximum service voltage of. 30 kV has become available. This breaking capacity corresponds to the highest short-circuit.
