something wrong kung palaging nagti-trip ang breaker. over load
not all the time naman dahil sa overload case, yung nasa workshop o repair ng mga industrial motors, nagkakaroon sila ng tripping ng CB because of shorted motor. kaya advice lang na e check yung CB para sa posibling damage ng CB. kahit minsan sa mga electronics repair shop, hindi maiiwasan sa pagsaksak mo ng unit ay shorted pala. |

If it's an ordinary breaker, then there is overcurrent condition (current greater than the circuit breaker AT rating).
If it is a special breaker GFCB (Ground Fault Circuit Breaker) or AFCB (Arc Fault Circuit Breaker), then overcurrent is not the only cause for tripping.

yup, yun po bang GFCB (Ground Fault Circuit Breaker) = sa ELCB (Earth Leakage Circuit Breaker)? |

that's right. ELCB noong araw, ngayong maraming na ang nakoryente sa banyo at alababo dito North America, tinawag na nilang GFCB. |

If you are operating an industrial plant that require coordination protection, you use high kaic rated fuse or breaker.
If your application is a residential unit with no strict requirement for a maintenance program, use a low kaic breaker or fuse.
hindi ba depende un sa duty ng CB may mababa may mataas na interrup capacity sa isang installation. kasi ang purpose nun is to localize the problem. so sa ind. plant may mababa rin. mas mababa sa branch mataas sa main para kung may problem sa isang portion dun lang, kasi kung napataas ang kAIC sa branch kesa sa main shutdown buong plant.. nakupow malaking hayop un.. dapat proper coordination. |

That's right. We call that selective coordination, isolating a fault condition. Coordination study is one of the electric utility's requirement before commissioning a distribution system. Ayaw nilang madamay pag may fault sa planta. |

dba normal naman yan sa mga plant? hindi ka kakabitan ng power pag isa lang breaker mo sa lahat ng makina hehe |

pag ang combined starting amperes lampas sa 100A siguradong mag trip. |

Mas magandang magkahiwalay breaker nila kasi masyado dynamic duty cycle ng wmachine. Pwedeng magtrip(magkasabay) o hindi bumitaw ang breaker kung cement mixer lang ang load kapag may problema .
