R  _______________________________________________________________WIRE IDENTIFICATION BY THE SUPPLIER - DESCRIPTION AND OPERATION
R R R R R R R R R R  _______1. General This topic covers the identification and the markings made by the manufacturer during the manufacture of the wires and cables. Définitions : Conductor : The conductor is the conducting element of the cable formed from one or more strands. Core : Assembly of a conductor and insulation which then form part of a complete single or multiconductor cable. Cable or wire : A cable is an assembly consisting of a conductor, insulation and, where applicable, a sheath, screen or jacket.
 __________________2. P/N Identification All the wire types (US and Metric) agree with Standards (ABS, ASNE, EN, NSA,...). The wires are identified as follows:
 A. General case: ABSXXXX EXXXX NSAXXXXXX  XX XX XX  XXXXXX
 --------- -- --
| | | | | ---------- Wire gauge | | | -------------- Wire type code | ---------------------- Standard P/N (Not written on the wire)
 B. Specific cases
 (1) For E0260, E0261 and E0262 P/Ns: E026X XX XX - X
 ----- -- -- -
| | | | | | | |--------- Color code (Ref. para. 7.) | | | | | | ------------- Wire gauge | | | | --------------------- Wire type code | |------------------------------- Standard P/N (Not written on the wire)
