Nonmetallic-sheathed (NM) cable is intended for protected locations—inside wall cavities, for example, not out in the weather or buried in the backyard. Inside the sheathing are individual wires. “NM-B” means the cable is rated for locations . BX cable comprises plastic-coated insulated wires of about 12- or 14-gauge rolled up together and protected using a ribbon-like metal sheathing. You might hear them being otherwise called MC, type AC, armored cable, . BX cable is required when a metal box must be grounded to the cable's sheathing—NM cannot do this. Also, BX cable can be installed in some exposed locations, Learn the origins of BX cable, where to use it, its pros and cons, and how to work with it. Nonmetallic, or NM, cable (commonly known by the brand name Romex) must be secured to electrical boxes at the point where the cable enters the box. This code requirement is an important safety feature that protects the wiring .
Where nonmetallic-sheathed cable or multiconductor Type UF cable is used, the sheath shall extend not less than 6 mm (1∕4 in.) inside the box and beyond any cable clamp. Except as provided in 300.15 (C), the wiring shall be firmly secured to the box or conduit body. Use a metal electrical box when metal-sheathed cable (also called armored BX cable) or metal conduit runs in or out of the box. Metal cable and conduit depend on the contact from its metal sheathing to the metal box to complete grounding. Whether it’s the first box in a line or the only one on an entire circuit, every metal box needs to be grounded. Grounding a box is as simple as connecting the incoming and outgoing ground wires to a pigtail, and then connecting the pigtail to the box with a .
The NEC does not presently provide a minimum cable sheath requirement for the metal boxes with cable clamps, as is addressed in 314.17(C) for nonmetallic boxes. This wording will provide a comparable requirement and assure that the cable clamp will not bear on unprotected conductors.
