Why making capacity of the circuit breaker is higher than breaking capacity?
Making capacity is the max fault current it can carry during closing of breaker, e.g. You are closing a breaker on fault.
The making capacity is always higher because it is expressed in peak value not rms, and also because of the DC offset, voltage and PF while closing.
