 Wire Identification  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. For example AKA gauge 24 has 19 strands diameter 0.127 mm (0.01 in.).  B. Metric (M) Types: The Metric (M) wire types are installed on the other Airbus A/C for weight saving. For example CF gauge 24 has 19 strands diameter 0.12 mm (0.0050 in.). P/N Identification    All the wire types (US and Metric) agree with Standards (ABS, ASNE, EN, NSA,...). The wires are identified as follows: Standard P/N  -  Wire type code - Wire gauge  ABSXXXX - XX - XX EXXXX - XX -  XX NSAXXXXXX -  XX -  XX     For EN Part Numbers: Standard P/N - Code letter for number of cores - Wire gauge code - Insulation color code  ENXXXX - XXX  X  XXX X If it is necessary to replace between US and metric types of wires on the aircraft  y...

 Electrical Standard Practices Manual (ESPM) Introduction to ESPM: The Electrical Standard Practices Manual (ESPM) gives descriptive data and procedures for the electrical installations on all aircraft of the AIRBUS family. The standard practices information in this manual tells you how to do maintenance for the continued airworthiness of the aircraft. The ESPM is part of the Instructions for Continued Airworthiness (ICA). The ESPM always gives the best practices to do the installations or the repairs. There are several chapter 20, depending on the vendor responsible for the system (ECE, Honeywell, etc.) but whatever the vendor, their chapter 20 follows the same layout. The data contained in the ESPM includes:  - Description of electrical items. - Removal/Installation of electrical items. - Electrical checks. - Repair procedures. - Damage assessment procedures. - Other procedures as necessary (Cleaning, Inspection/Check, etc.).  The Electrical Standard Practices data ...
