What is the primary feature of Breaker and Half Configuration?

The primary feature of Breaker and Half Configuration is that it employs two main buses which are each energized, with three circuit breakers positioned between them. This design allows for excellent reliability and operational flexibility. In this configuration, it is possible to isolate individual circuit breakers for maintenance without disrupting the entire system, as the other bus can continue to supply power. This enhances the system's redundancy, ensuring that if one bus or breaker fails, the other can maintain the operation of the electrical distribution network, thereby allowing for uninterrupted power supply and maintenance efficiency. The presence of two buses is critical because it allows for more complex switching and operational scenarios, contributing to better system reliability and flexibility.
