Surface Mount Metal Raceway
Greetings,
Imagine a square room with four walls called N E S W. Walls E, W are masonry and walls N, S are framed. I am trying to run two NM cables from boxes on N to boxes on S. I wanted to bridge the masonry walls with a piece of surface mount. I am using the Surface Mount Metal Raceway products featured on this page: http://tinyurl.com/bxrgw I would like two 12-2 NM cables to enter the raceway inside a frammed wall (N), pass through 15 ft of straight run (W), and exit the raceway behind another wall (S). My plan was to use two of the fittings BWl7 (see link) to convert between the raceway and a 1/2" knockout. I would put a cable clamp into the knockout to clamp the two NM cables. I would strip the outer sheathing off the NM cables for the duration the the cable was inside the raceway. Is this legal? (and if not why) Can I bury the BWl7 fittings inside the wall or should they be exposed at the very edge of the wall with the NM concealed within the wall? I have heard conflicting opinions and I wanted to get the definitive answer from Usenet before beginning work. Thank you for your time, William PS: I called their tech support number to ask and the two people I talked to did not know what NM cable was. |
