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.
âMCBâ stands for âMiniature Circuit Breakersâ while âMCCBâ is âMolded Case Circuit Breaker.â. The main difference between the two is their capacity with the MCB rated under 100 amps with an interrupting rating of under 18,000 amps.Consequently, their trip characteristics may not be adjusted since they basically cater to low circuits.ircuit breakers are usually reset after they have been âtripped.â Both MCB and MCCB are highly durable and could last for years depending on the manufacturer. When choosing between using an MCB and an MCCB, it is important to consider the amount of power that would be coursing through the device.
