During local and remote operation, which color should the motor run light be to indicate it is energized?

• A. Red
• B. Yellow
• C. Green
• D. Blue

Answer: (C)

The motor run light being green to indicate that it is energized is a widely accepted convention in industrial and engineering contexts. The green color generally symbolizes "go" or an active state, making it intuitively clear to operators and personnel that the motor is operational and functioning as intended. In many systems, red is typically used to signify alarms, faults, or danger, while yellow often indicates caution or a warning that attention may be needed without implying that the system is currently safe or operational. Blue is less commonly associated with the status of machinery but might be used for other specific signals in a plant’s control system. Therefore, using green for the motor run light aligns with standard practices and helps ensure safety and effective communication for system operations.
