MCB, RCCB, or MCCB: Which circuit breaker to choose?
A circuit breaker is an absolute necessity and one of the most significant safety devices in your home. Circuit breakers discontinue the power flow whenever there is an overflow of electric current in a building. Without circuit breakers (or fuses, which were used before some time), the electrical wiring in the household is futile because a simple wiring fault or equipment failures can cause fires. Several types of circuit breakers are used in house wiring to protect it from the potential electrical hazards due to electrical overloads. The most widely used circuit breakers are Miniature circuit breakers (MCBs), Residual current circuit breakers (RCCBs) and Molded Case Circuit Breaker (MCCBs). Here is the quick guide to the types of Circuit Breakers. Miniature Circuit Breakers (MCB): An MCB automatically switches off the electrical circuit during an overload as well as a faulty condition. MCBs have replaced fuses in a low voltage electrical network as they are much more s...
