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.
On the other hand, an MCCB comes with an adjustable trip characteristic for the higher models. Usually, this type of circuit breaker would provide amps as high as 2,500 or as low as 10 depending on what is necessary. Their interrupting rating can be around 10,000 amps to 200,000 amps.
