Except as specifically limited in this section, the wiring methods and materials included in this Code shall be used in mobile homes. 70-596 NATIONAL ELECTRICAL CODE (a) Nonmetallic Boxes. Nonmetallic boxes shall be permitted only with nonmetallic cable or nonmetallic raceways. (b) Nonmetallic Cable Protection. Nonmetallic cable located 15 inches (381 mm) or less above the floor, if exposed, shall be protected from physical damage by covering boards, guard strips, or raceways. Cable likely to be damaged by stowage shall be so protected in all cases. (c) Metal-Covered and Nonmetallic Cable Protection. Metal-covered and nonmetallic cables shall be permitted to pass through the centers of the wide side of 2-inch by 4-inch studs. However, they shall be protected where they pass through 2-inch by 2-inch studs or at other studs or frames where the cable or armor would be less than 1½ inches (38 mm) from the inside or outside surface of the studs where the wall covering materials are in contact with the studs. Steel plates on each side of the cable, or a tube, with not less than No. 16 MSG wall thickness shall be required to protect the cable. These plates or tubes shall be securely held in place. (d) Metal Faceplates. Where metal faceplates are used, they shall be effectively grounded. (e) Installation Requirements. If a range, clothes dryer, or similar appliance is connected by metal-covered cable or flexible metal conduit, a length of not less than 3 feet (914 mm) of free cable or conduit shall be provided to permit moving the appliance. The cable or flexible metal conduit shall be secured to the wall. Type NM or Type SE cable shall not be used to connect a range or dryer. This shall not prohibit the use of Type NM or Type SE cable between the branch-circuit overcurrent-protective device and a junction box or range or dryer receptacle. (f) Raceways. Where rigid metal conduit or intermediate metal conduit is terminated at an enclosure with a locknut and bushing connection, two locknuts shall be provided, one inside and one outside of the enclosure. Rigid nonmetallic conduit or electrical nonmetallic tubing shall be permitted. All cut ends of conduit and tubing shall be reamed or otherwise finished to remove rough edges. (g) Switches. Switches shall be rated as follows: (1) For lighting circuits, switches shall be rated not less than 10 amperes, 120-125 volts, and in no case less than the connected load. (2) For motors or other loads, switches shall have ampere or horsepower ratings, or both, adequate for loads controlled. (An "ac generaluse" snap switch shall be permitted to control a motor 2 horsepower or less with full-load current not over 80 percent of the switch ampere rating.) (h) Free Conductor at Each Box. At least 4 inches (102 mm) of free conductor shall be left at each box except where conductors are intended to loop without joints. (i) Under-Chassis Wiring. (Exposed to weather.) (1) Where outdoor or under-chassis line-voltage (120 volts, nominal, or higher) wiring is exposed to moisture or physical damage, it shall be protected by rigid metal conduit or intermediate metal conduit. The conductors shall be suitable for wet locations. Exception: Electrical metallic tubing or rigid nonmetallic conduit shall be permitted where closely routed against frames and equipment enclosures.
