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.
Re: Circuit Breaker size. If it is possible for the supply to run full out for 3 hours or more, then 200A *1.25 for the size of the breaker and ampacity of the wire.
