UL 1569 Thhn Inner Mc/AC/Bx Cable

 

APPLICATION
Type MC Cable - Isolated Ground is constructed with soft-drawn copper, Type THHN/THWN
conductors rated 90°C dry available in sizes 12 AWG and 10 AWG, and two insulated grounding conductors--one solid green and the second green with yellow stripes. The conductors are cabled together and a binder tape bearing the print legend is
wrapped around the assembly. Aluminum interlocking armor is applied over the assembly. 

Type AC Cable BX is constructed with soft-drawn copper, Type THHN insulated conductors which are
individually wrapped with a moisture-resistant, flame-retardant paper covering. Aluminum interlocking armor is applied over the assembly. A 16 AWG aluminum bond wire is placed inside the armor, runs longitudinally and is in intimate contact with the armor for its entire length.
