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.
The size of a breaker is the maximum current it allows to pass without tripping, which should be 125 percent of the maximum current expected to pass continuously through the circuit. A 15-amp breaker, therefore, trips at 15 amps although the maximum continuous load through the circuit rates only 12 amps.
