Where spare, separately switched, ungrounded conductors
are provided to a ceiling mounted outlet box, in a
location acceptable for a ceiling-suspended (paddle) fan in
single or multi-family dwellings, the outlet box or outlet
box system shall be listed for sole support of a ceiling suspended
(paddle) fan.
the section says spare conductors. does that mean that if you were to run a 14/3 with one coductor being a spare then the box is required,or if the box is a spare its required? a bit confusing.
