1 Metal lad able, rmored able and Flexible Metal Metal lad able, rmored able and Flexible Metal onduit rmored able (Type ) Ref. NE rticle 20 National Electrical ode defines type armored cable as, fabricated assembly of insulated conductors in a flexible metallic enclosure. T H HH U L thermoplastic (Type T) insulation. rubber insulation of code grade. rubber insulation of the heat resistant (5 ) grade. rubber insulation of the heat resistant (90 ) grade. rubber insulation of latex grade. Used as a suffix, it indicates that a lead covering has been applied over the conductor assembly. ll armored cables may employ copper or aluminum or copperclad aluminum conductors with the following sizes and are rated for 600 volts or less: No. 4 WG to No. WG opper No. 2 WG to No. WG luminum or opperclad luminum Type cables except L carry an internal bonding strip of copper or aluminum in intimate contact with the armor for its entire length. rmored cable can be used for both exposed or concealed locations. With lead-covered conductors (Type L), the cable can be embedded in masonry or concrete and can be used in damp locations or where exposed to oil. rmored cable is not permitted in locations where it will be subjected to physical damage or corrosive fumes. rmored cable cannot be used for direct burial in earth. With minor exceptions, armored cable is also not permitted to be used in hoists or elevators, storage battery rooms, any hazardous locations, in commercial garages and in theaters or similar locations. odes require that cable shall be supported with straps or staples without damaging conductors and also limit the minimum bend radius to 5 times the diameter of type cable. ertain precautions are prescribed in code where cable is installed through joist rafters or similar wood members. ccording to NE 20 where armored cable is terminated, a fitting is required to protect conductors from abrasion. In addition, a bushing is required between the conductors and armor. Design of fitting has to be such that the insulating bushing is visible for inspection. ushing is not required with lead-covered cables when properly installed.

2 Metal lad able, rmored able and Flexible Metal Metal lad able, rmored able and Flexible Metal onduit continued Flexible Metal onduit Ref. NE rticle 48 Flexible metal conduit can be used for exposed or concealed work in dry locations. It can be used for wet locations provided conductors within are lead covered or other approved type. Flexible metal conduit cannot be used underground or embedded in poured concrete or aggregate. With rubber covered conductors, the conduit cannot be exposed to oil, gasoline or other materials having a deteriorating effect on rubber. With minor exceptions use of flexible metal conduit is not permitted in hoists, in storage battery rooms and in any hazardous locations. Use of flexible metal conduit is restricted to systems under 600 volts. ccording to NE rticle 50-5, flexible metal conduit no longer than six feet and containing circuit conductors protected by overcurrent device rated for 20 amps or less is suitable as a grounding means provided, it is terminated in fittings approved for the purpose. Flexible metal conduit longer than six feet is permitted to be used as a grounding means provided the conduit and the fitting are approved for the purpose. To date, there is no flexible metal conduit approved for the purpose by the Underwriters Laboratories. In lass I & II, Division 2 hazardous areas, the conduit itself cannot be used as the grounding means. bonding jumper must be installed in accordance with NE Section Flexible metal conduit is available with steel or aluminum armor in trade size 5 " to 4". With few exceptions where 5 " and " trade sizes are used, ode prohibits use of conduit less than d" trade size. ends in concealed work are restricted to 60 degrees total. No angle connectors are permitted in concealed raceway installations.
