(e) mineral-insulated cable, aluminum-sheathed cable, or copper-sheathed cable shall not be used with types of thermal insulation that are liable to have a corrosive action on the sheath.
(1) An identified conductor shall not be used as a conductor for which identification is not required by these Rules; however, in armoured cable, aluminum-sheathed cable, copper-sheathed cable, and non-metallic-sheathed cable work, the identified conductor shall be permitted to be rendered permanently unidentifiable by painting or other suitable means at every point where the separate conductors have been rendered accessible and visible by removal of the outer covering of the cable.
(2) Where armoured cable, aluminum-sheathed cable, copper-sheathed cable, or non-metallic-sheathed cable containing an identified conductor is used for single-pole, three-way, or four-way switch loops, it shall not be necessary to render the identified conductor permanently unidentified at the switch if the connections are made so that an unidentified conductor is the return conductor from the switch to the outlet.
(3) Where armoured cable, aluminum-sheathed cable, copper-sheathed cable, or non-metallic-sheathed cable is used so that the identified conductor forms no part of the circuit, the identified conductor shall be cut off short or other suitable means shall be employed to indicate clearly that the identified conductor does not form part of the circuit; this shall be done at every point where the separate conductors have been rendered accessible and visible by removal of the outer covering of the cable.
(f) aluminum-sheathed cable or copper-sheathed cable
