What type of conduit is required to supply power to the electrical source on a water fixture?

• A. Flexible conduit
• B. Schedule 40 conduit
• C. 12-3 wire
• D. 3 phase motor

Answer: (B)

Wiring for outdoor water fixtures must be protected by a rigid, weatherproof raceway that can withstand moisture and physical damage. Schedule 40 conduit (rigid PVC) is designed for outdoor use and wet locations, providing a sturdy, continuous path for conductors to the electrical source of a water feature. It offers good protection, is relatively easy to install on walls or underground with standard fittings, and stays durable in exposed environments. Flexible conduit, while handy for tight bends or connections near the fixture, is more susceptible to damage and moisture intrusion over time, so it isn’t the preferred main supply raceway for a water feature. 12-3 wire is a type of conductor assembly, not a conduit, and a three-phase motor describes a load rather than the conduit needed to bring power, which isn’t the typical setup for a standard water feature.
