9.2.2 Two incomers without a tie breaker (feeder selective)
NO
NOTE!
TE!
Please note that there is another MV application titled "Two incomers without a tie breaker",
differentiated by whether or not they are feeder selective.
In this application the scheme selected with AQ-101 is SS:4, and this means that this
application is feeder selective. When the sensor channel S1 of an AQ-101 unit detects light,
T1 sends a tripping signal only to its breaker. Similarly, when the sensor channel S2 detects
light, T2 sends a tripping signal only to its breaker.
