Why Does My MCB Keep Tripping? 7 Common Causes & Solutions
In Electrical, There are two things ‘ON’ & ‘OFF’. Things seems pretty much simple. But Electricity is also dangerous if not handled in an appropriate way. It is the safety of human & safety of machines which makes the an Electrical system complex. In Electrical safety, MCB is the most basic tool. In this post, […]
MCB Selection Criteria
Method or criterion : Which MCB suits your load !
MCBs (Miniature Circuit Breakers) are electromechanical devices that protect against overloads and short circuits while serving as switches. Proper selection of MCBs is crucial and involves six criteria: supply type, rated current, number of poles, curve type, breaking capacity, and auxiliary accessories. Understanding these factors ensures effective protection in electrical systems.
