Q. How close can I run underground service conductors in a raceway to an outdoor pool?

A. According to 680.10, underground wiring isn’t permitted under or within 5 feet horizontally from the inside wall of permanently installed pools, storable pools, outdoor spas, outdoor hot tubs, or fountains.

However, where space limitations prevent wiring from being at least 5 feet away, underground wiring would be permitted if within rigid metal conduit, intermediate metal conduit, or rigid nonmetallic conduit having a minimum burial depth of 6 inches for metal raceways and 18 inches for nonmetallic raceways.
