Southwire’s quadruplex or paralleled 600 volt secondary UD cable meets or exceeds the following ASTM specifications:
Conductors are stranded, compressed 1350-H16/H26 aluminum, insulated with cross-linked polyethylene. Neutrals are identified by triple yellow extruded stripe. Cables with “YES” neutrals have sequential footage markers. Conductors are durably surface printed for identification. Three phase conductors and one neutral conductor are cabled together to produce the quadruplex cable configuration.
