If the circuit breaker closest the faulty point, fails to trip the . circuit breaker. just next to this breaker will trip as back up. The operating time of relay associated with protection of line should be as minimum as possible in order to prevent unnecessary tripping of circuit breakers associated with other healthy parts of power system.

The Number 2 circuit breaker in the panel box supplies current only to disconnect Number 2, which in turn controls the current to motor Number 2. This current to motor Number 2 can be shut off by the Number 2 circuit breaker or the Number 2 disconnect. If the purpose of the circuit is obvious, no identification of the disconnect is required.

CHAPTER 1
For circuit breakers there are a number of basic requirements which are desirable in the control circuit. These features can be found in the motor, solenoid, spring (stored energy) and pneumatically-operated Circuit Breakers. A good understanding in these control circuit features will allow an intelligent approach to trouble-shooting.
