A miniature circuit breaker mcb is an automatically operated electrical switch used to protect low voltage electrical circuits from damage caused by excess current from an overload or short circuit. This kind of circuit is used for dishwashers whirlpool spas and other locations where water contact is likely. In residential applications single pole breakers protect 20v branch circuits and two pole breakers protect 240v branch circuits.

The fuse may not sense it but the miniature circuit breaker does it in a more. Locate the service disconnect or main circuit breaker in the panel and set it to the off position. In this video you will learn about how to wire double pole mcb miniature circuit breaker with wiring connection diagram in english language. Nowadays we use an mcb in a low voltage electrical network instead of a fuse.

This circuit breaker is likely to have the largest amp value and will be located either at the top or bottom of the panel. Wiring a gfci circuit breaker. The main function of an mcb is to switch the circuit i e to open the circuit which has been connected to it automatically when the current passing through it mcb exceeds the value for which it is set.

Turn off the power supply to the electrical panel. Mcbs are typically rated up to a current up to 125 a do not have adjustable trip characteristics and can be thermal or thermal magnetic in operation. If you don t see a circuit breaker labeled service disconnect or main in the panel it is likely in another. For typical miniature circuit breakers this rating is 2 to 125 a.

This diagram illustrates wiring for a circuit breaker with a built in ground fault circuit interrupter or gfci. The voltage rating of a circuit breaker can be higher than the circuit voltage but never lower. A miniature circuit breaker mcb automatically switches off the electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition.
