WebOct 2, 2024 · Circuit Overloads. One of the main reasons why MCBs trip is as a result of circuit overload. It occurs when you try to make a circuit give more electric currents than its actual capacity. This will result in the circuit overheating, which then puts all the electrical devices connected to the circuit at risk. Take, for instance, if your desktop ... WebApr 18, 2024 · In this case, the current level is high enough to pass through the curves where Breakers 1 and 2 are selective i.e. to the right of the intersection of their curves. Therefore, we can see that breaker 2 will detect the current before breaker 1 and will trip before it as well. So, selectivity is maintained in this scenario. TCC of a Fuse:
