shall be used in mobile structures.
(b) Nonmetallic outlet boxes shall be
				acceptable only with nonmetallic cable.
(c) Nonmetallic cable located fifteen inches
				(15") or less above the floor, if exposed, shall be protected from physical
				damage by covering boards, guard strips, or conduit. Cable likely to be damaged
				by stowage shall be so protected in all cases.
(d) Metal-clad and nonmetallic cables shall
				be permitted to pass through the centers of the wide side of two inch (2") by
				four inch (4") studs. However, they shall be protected where they pass through
				two inch (2") by two inch (2") studs or frames where the cable or armor would
				be less than one and one-half inches (1 1/2") from the inside or outside
				surface. 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.
(e) Where metallic faceplates are used they
				shall be effectively grounded.
(f)
				If a range, clothes dryer, or similar appliance is connected by metal-clad
				cable or flexible metal conduit, a length of free cable or conduit shall be
				adequately secured to the wall. A length of not less than three feet (3') of
				free cable or conduit shall be provided to permit moving the appliance. Type NM
				of 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.
(g) Threaded rigid
				metal conduit and intermediate metal conduit shall be provided with locknut
				inside and outside the box, and conduit bushing shall be used on the inside.
				Rigid nonmetallic conduit shall be permitted. Inside ends of the conduit shall
				be reamed.
(h) Switches shall be
				rated as follows:
(1) For lighting circuits,
				switches shall have a ten (10) ampere, one hundred twenty/one hundred
				twenty-five (120/125) volt rating; or higher if needed for the connected
				load.
(2) For motors or other
				loads, switches shall have ampere or horsepower ratings, or both, adequate for
				loads controlled. (An "AC general use" snap switch shall be permitted to
				control a motor two (2) horsepower or less with full-load current not over
				eighty percent (80%) of the switch ampere rating.)
