(1) Listed electrical conduit can only be installed and used in accordance with its listing (i.e., as an electrical raceway for electrical conductors). If used as a sleeve for electrical conductors or other listed electrical conduits, the installation of a listed electrical conduit will be assumed to be for use as an electrical raceway and must be installed as allowed by chapter 19.28 RCW and this chapter (e.g., owner exemption, electrical contractor, etc.). EXCEPTION: Electrical nonmetallic elbow fittings may be connected to piping other than electrical conduit for the purposes of enclosing mechanical piping systems provided the elbows are distinctively marked to indicate their use as nonelectrical fittings prior to installation. For underground installations outside of buildings, elbows used for purposes other than electrical must be substantially painted to match the color of piping to which they are connected. 011 Deteriorating agents. (2) Electrical equipment and wiring that has been submerged or exposed to water must comply with the following: (a) All breakers, fuses, controllers, receptacles, lighting switches/dimmers, electric heaters, and any sealed device/equipment (e.g., relays, contactors, etc.) must be replaced.
