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 current minimum requirement for an electric breaker panel is 100 amps. Panels come in 100, 150, 200 and 400 amp capacity. Old panels, especially those with the old glass fuses, are prone to tripping and can pose a fire hazard.
