Which term describes the requirement that water must escape from a conduit system?

• A. Drainage for a raceway
• B. Sealing raceway
• C. Porcelain or glass insulators
• D. Minimum spacing required between conductors

Answer: (A)

Water inside a conduit system needs a path to escape so it doesn’t pool and cause corrosion, short circuits, or other moisture-related problems. The term that describes this requirement is drainage for a raceway. Designing for drainage means the raceway provides a natural or intentional route for moisture to leave, such as sloped runs or drainage openings. Sealing a raceway aims to keep water out, which is the opposite goal. Insulators made of porcelain or glass relate to insulating conductors, not removing water from the conduit. Minimum spacing between conductors concerns how far apart conductors must be kept for safety and insulation, not moisture management.
