A 32 amp MCB (Miniature Circuit Breaker) will trip when the current flowing through it exceeds 32 amps. MCBs are designed to protect electrical circuits from overcurrent situations, which can lead to overheating and potential fire hazards. Once the current surpasses the rated amperage, the MCB will trip to interrupt the circuit and prevent further damage.

ReneThe circuit protected by a 32 amp circuit breaker will trip when the circuit loading reaches on or about 32 amps.
Theoretically a 32 amp breaker will not trip until current exceeds 32 amps. But this is affected by actual conditions such as ambient temperature, the integrity of the termination, the temperature of the breakers immediately adjacent to it, etc. In the United States the NEC requires that you not knowing load a breaker to greater than 80% of its rating. This avoids what is called nuisance tripping.
Most common MCBs have an inverse-time component. This means the higher the current the faster it will trip. A current of 100 amps caused by a short circuit will trip faster than 33 amps which would most likely be an overload condition. The difference may not be noticeable without testing equipment.

Do you need 15A MCB for 15A socket outlet?
Yes, it is recommended to use a 15A miniature circuit breaker (MCB) for a 15A socket outlet to ensure proper protection against overcurrent situations. Using a matching MCB helps safeguard the outlet and connected devices from potential electrical hazards.
Can you have a 15 amp appliance on a 32 amp supply?
Yes, you can have a 15 amp appliance connected to a 32 amp power supply. The appliance will only draw the current it needs, in this case 15 amps, so it will not overload the 32 amp supply.
How many watts can you use with a 32amp mcb?
A 32 amp MCB (miniature circuit breaker) can handle a maximum load of 7,360 watts at 230 volts (32 amps x 230 volts = 7,360 watts). It is important not to exceed this limit to prevent overloading the circuit and causing damage.
How many amps doe it take to trip a 20 amp breaker?
A 20 amp breaker will trip if the current exceeds 20 amps for an extended period of time. It is designed to protect the circuit from overheating and causing a fire hazard. So, it would take more than 20 amps to trip a 20 amp breaker.
Does mcb trip if a short circuit occurs?
Yes, a breaker will trip if there is a short circuit occurring on the breaker's connected load. The breaker will also trip on an overload condition when the current rises above the breakers trip set point.
