No good idea. The CT may not function well at a load beyond 630 amps. It may even fail at higher load (than 630 amps)
LBB is local breaker protection
Lbb means local breaker backup protection
Generator Breaker Status
Overcurrent current protection is for the wires
Breaker is a protective device that cuts off the electrical circuit in case of fault. The additional breaker can be provided as backup protection locally, which is known as local back up.
The selection of overload protection for motors is taken from a table in the electrical code book. It is based on the full load current rating of the motor.
If the circuit breaker is in the off position there is no need of overload protection. Overload protection monitors the load amperage, If there is no amperage through the circuit there is nothing to monitor.
circuit breaker, or "resettable fuse", which is a reallya small circuit breaker in the housing of a fuse
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
A circuit breaker is an overcurrent device that can be reset after it has opened.
please you give me reply to answer.
Fuses do not provide protection against ground faults. Protection against a ground fault can be provided by breakers. If a fuse blows, it has to be replaced. If a breaker is tripped to off due to a surge in electrical current, the breaker can be reset.
