When the MC switch is set to 2 off (down), what happens to relay 1K-F082 and MC2?

When the MC switch is set to 2 off (down), what happens to relay 1K-F082 and MC2?

• A. The relay is energized, and MC2's power is removed
• B. The relay is deenergized, and MC2's power is removed
• C. The relay remains energized and MC2 remains powered
• D. No change to relay or MC2

Answer: (A)

In this position, the MC switch energizes the coil of relay 1K-F082. Energizing the relay changes its contact state to interrupt the power path to MC2, so MC2 loses power. This is a common control pattern where a switch position directly drives a relay to disable a subsystem. If the coil were not energized, MC2 would not be intentionally disconnected, so the current position uniquely results in the relay being energized and MC2’s power being removed.
