The BAK-14 configuration with 20 support boxes is installed on runways of widths?
Correct Answer:
200 feet or 300 feet
Explanation:
The setup is matched to runway width so the power distribution and feeder points line up properly along the runway. With 20 support boxes, this BAK-14 configuration is designed to span runways that are 200 feet wide or 300 feet wide. Those widths allow the electrical feeders, transformers, and lighting circuits to be arranged with appropriate spacing, keeping conductor runs within limits and making maintenance practical. If the runway is wider or narrower, a different number of boxes or a different configuration is required, so 200 or 300 feet is the standard pairing for this setup.
