Is it acceptable to have a line voltage dimmer in a plenum that contains a fan to keep it cool? This phase control dimmer is in a metallic enclosure and has a UL916 mark. Someone told me that if it has a fan, it would be unacceptable. Under the NEC 300.22 for equipment in a plenum, it appears acceptable. Are there other areas in the code that might prohibit this?
