What is a 6 amp MCB used for?

Typically, a circuit breaker or fuse of 6 amps is used. The conductors in lighting cables therefore need not be very thick. One 100 Watt bulb uses less than half an amp as shown below. Therefore, a 6 amp mcb could safely protect a circuit feeding more than ten 100 W bulbs.
