Is a 4" diameter nipple that is 8" in length considered to be a conduit? The scenario is that we have this 4" diameter, 8" long rigid nipple that allows passage of three conductors from one panel to another. Due to its short length, is this still considered to be a conduit (raceway), thus mandating the use of Table 310.15(B)(16) "Not more than three current-carrying conductors in raceway, cable, or earth..."; or can this be considered free air, since its length is so short?
