Miniature Circuit Breakers - MCB
MCBs or Miniature circuit breakers have almost replaced fuses in newer
consumer units. Their main advantage is that they can be manually reset
without having to replace wire as in the case of the traditional fuse. They
are provided with a button or a lever that can be used to reset it.
The tripping of MCB indicates that there is some problem in the circuit.
Either it has been overloaded or a short circuit has occurred somewhere in
the system. It is essential to identify the problem and sort it out before
resetting the MCB.
Switch off the main power supply and all the appliances connected to the
circuit to ensure it is not overloading. Then reset the MCB. Finally put on
the main switch of the consumer unit. If the MCB resets itself instantly
once again, then it means a fault is still occurring. The fault must be
cured before switching on the MCB.
