550.15 Wiring Methods and Materials. Except as spe cifically limited in this section, the wiring methods and materials included in this Code shall be used in mobile homes. Aluminum conductors, aluminum alloy conduc tors, and aluminum core conductors such as copper- clad aluminum shall not be acceptable for use as branch-circuit wiring.

(A) Nonmetallic Boxes. Nonmetallic boxes shall be permitted only with nonmetallic cable or nonmetallic raceways.

(B) Nonmetallic Cable Protection. Nonmetallic cable lo- cated 380 mm (15 in.) 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 by 4 studs. However, they shall be protected where they pass through 2 by 2 studs or at other studs or frames where the cable or armor would be less than 32 mm (l'/4 in.) from the inside or outside surface of the studs where the wall covering materials are in contact with the studs.

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, electrical nonmetallic tubing, or surface race way shall be permitted. All cut ends of conduit and tubing shall be reamed or otherwise finished to remove rough edges.
