3. Wire Types There are two families of wire types:
A. United States (US) The United States (US) wire types are installed on A300/A310/A300-600. Their core diameter has US diameters.
e.g. AKA gauge 24 has 19 strands diameter 0.127 mm (0.0050 in.).
B. Metric (M) types: The Metric (M) wire types are installed on the other Airbus A/C for weight saving.
e.g. CF gauge 24 has 19 strands diameter 0.12 mm (0.0047 in.).
C. Wire type equivalence table
(1) US -> Metric - one way equivalence tables If it is necessary to replace a US type wire on the aircraft and if the US type wire is no longer available, you can use an equivalent Metric wire (Ref. one way equivalence tables (US->Metric)). All the Metric wires are available. |l

_______________4. Wire Type Codes Tables 1-A to 1-Y give the list of the wire type codes in alphabetic sequence and the related standard P/Ns (US and Metric wire type families). It is the wire type code which is written on the wire and not the standard P/N.
____NOTE : You must use the applicable tools to strip the wires (US or Metric). Ref. 20-25-11.
