MCB is one of the genius inventions of mankind that is massively underappreciated. MCB is an abbreviation for Miniature Circuit Breaker, and this invention has been saving us thousands and lakhs of damage every day from short circuits and overloads electrical damage.<\/p>\n\n\n\n
Normally when an MCB trips, we should be thankful that the MCB worked and it just saved us from fluctuations in electricity damaging our appliances connected throughout our house. But when the same MCB keeps on tripping multiple times a day, it becomes quite irritating. So today, we will be sharing important checks and \u2018what to dos\u2019 to help you correct the faulty MCB or replace it with a new one.<\/p>\n\n\n\n
MCB breaks the circuit whenever there is an overload or short circuit in Electricity. Thus, saving expensive appliances which would have otherwise got damaged.<\/p>\n\n\n\n
The metallic plate inside the MCB overheats and expands whenever there is a current overload or short circuit. This metal expanding, in turn, releases a spring mechanism which turns it off breaking the connection and circuit.<\/p>\n\n\n\n
Some MCB nowadays has an Electromagnetic mechanism, where a metal part inside turns into a magnet when a certain level of current flows through it. This in turn displaces the switch and turns it off breaking the circuit.<\/p>\n\n\n\n

f you have recently purchased the circuit breaker and after coming back home and installing it you realised that there is no electricity continuation in the MCB or that the MCB Switch has become loose and free often referred to as \u2018Dolly Free\u2019 then this advice is for you. If you haven\u2019t recently purchased the MCB, then skip to the next section.<\/p>\n\n\n\n
If you\u2019re still reading then don\u2019t worry, this is a common occurrence in new MCBs and the reason could be dust in between the metal connector inside the MCB, or some spring or clip is loose inside the miniature circuit breaker. The very simple home solution for this problem which solves almost 70-80% of new MCB issues is banging the MCB on a flat surface on each side 3-5 times.<\/p>\n\n\n\n
