Which conductor installations are wet locations?

Which conductor installations are wet locations?

• A. Open conductors on insulators between a transformer and a building
• B. Conductor underground in PVC conduit
• C. Conductor in car wash, surface-mounted
• D. All of these

Answer: (D)

Wet locations are areas where water or other liquids can saturate surfaces or where moisture is consistently present. An installation with open conductors on insulators between a transformer and a building is outdoors and exposed to rain and humidity, so it is a wet location. A conductor underground in PVC conduit sits in soil and groundwater where moisture is present; underground conduits are treated as wet locations. A conductor in a car wash, surface-mounted, is regularly sprayed with water and cleaners, creating a wet environment. Because moisture or water exposure is present in each case, all of these are wet locations, and the conductors and equipment used there must be rated for wet locations.
