I am trying to find out if junctions made on communication wire, class 2 or 3, need a junction box. Looking at NEC 800-24, it references does reference 300.4(D) and 300.11 but does not mention 300.15 at all. Does this mean junctions do not need to be in a junction box? The circuit I am referring to is for an overhead speaker system I have running through out my building, drop ceiling, and plenum in half of my building. Any help would be greatly appreciated.
