Exam NETA_2 Topic 1 Question 71 Discussion

Actual exam question for NETA's NETA_2 exam
Question #: 71
Topic #: 1
In azone-interlocked low-voltage circuit breakerscheme, if the breaker responsible for clearing a fault fails to operate, which statement is correct?

Suggested Answer: C Vote an answer

Zone-selective interlocking (ZSI) improves coordination by allowing downstream devices to trip first while restraining upstream devices. If the downstream breaker fails to clear the fault, restraint signals are removed and thenext upstream breaker tripsto isolate the fault.
NETA Level 2 technicians must understand this fail-safe behavior when commissioning protection systems and validating coordination logic.
