What is drainage for a raceway?

• A. The requirement for water to be able to escape from a raceway
• B. The process of setting up a lamp holder in an outdoor environment
• C. The recommended positioning of lamps in relation to electric utilization equipment
• D. The lowest height that conductors must be above a surface

Answer: (A)

Drainage for a raceway means giving water a path to escape so moisture can’t collect inside the conduit or enclosure. In outdoor or damp locations, rain or condensation can enter a raceway, and if the water has nowhere to go, it can cause corrosion, insulation damage, or other electrical problems. So, raceways must be designed so any water can drain out, such as by allowing drainage at the lowest point or through suitable openings. The other options don’t address moisture management: they relate to lamp installation, lamp positioning, or conductor height, none of which deal with water leaving a raceway.
