This specification covers four categories of wire and cable: 6 mils, 8 mils, 10 mils and 19 mils nominal insulation thickness and is similar to the MIL-W-22759/80 and SAE-AS22759/80 constructions. With a maximum operating potential of 600 Vrms, these products establish the construction and performance requirements for different types of arc-resistant wire and cable. Composed of annealed copper, copper alloy, and aluminum, the temperature rating for each type is determined by the conductor or shield coating as listed:

(1) 260 Degree Celsius rated wire has a nickel coated copper conductor

(2) 260 Degree Celsius rated cable has a nickel coated copper conductor and nickel coated shield

(3) 175 Degree Celsius rated wire has an aluminum conductor

(4) 150 Degree Celsius rated wire has a tin coated copper conductor

(5) 150 Degree Celsius rated cable has a tin coated shield.

The construction of the wire is determined by the wire or cable type, class, and gauge size.  With fifty-six types and ten classes, the specifications cover sizes 26 AWG through 4/0 AWG.  When completed, all cable types are to use white PTFE tape for the outer wrap of the cable jacket unless a different color is specified.


We know the break-down of these part numbers can be tricky; below WireMasters provides a handy guide to help you determine the proper wire for your application.
