How many watts can you use with a 32amp mcb?

Answer 1

To answer this question a voltage must be stated. W = Amps x Volts.

Assuming that you keep a tidy house, your power factor is always 1 ,

and you derate your circuit breakers 10% for safety . . .

If in a 120v circuit . . . P120 = 0.9 x 120 x 32 = 3,456 watts

If in a 240v circuit . . . P240 = 0.9 x 240 x 32 = 2 x P120 = 6,912 watts

Answer 2

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.
