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.
Circuit Breakers. A circuit breaker is a switch that automatically interrupts electrical flow in a circuit in case of an overload or short.Homes built or rewired since the mid-1960s use circuit breakers to monitor the electricity coming into the home.oad capacity â When adding a new circuit and new circuit breaker, determine the amp size of the circuit breaker you need to install, based on the total circuit load. Keep in mind that the safety rating for circuit breakers is 80% of the maximum load.
