Which code is the Positive AC energy for switch repeater relays?

Explanation:
In signaling circuits, each device’s energizing path is labeled so you can identify exactly which supply powers which component. The switch repeater relay coil is driven by a specific Positive AC energy path, and that feed is designated by the code Wz. This labeling helps technicians trace the correct live supply to the repeater and avoid mixing it up with other feeds in the system, which is crucial for safe testing and correct operation. Since AC energizes with alternating polarity, the label represents the conventional reference for the energized side of the circuit, not a fixed polarity. So the code for the Positive AC energy feeding switch repeater relays is Wz.
