why making capacity is more than breaking capacity?
Answer Posted / vivek malhotra
Suppose the breaker is closing and at the same time a fault
occurs, then at that stage the arc will be very high due to
inrush and short circuit. But in case of breaking a circuit
when current is already flowing, the arc produced is less
as compared to during making of a circuit.
Hence the making capacity is always greater than breaking
capacity

1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
