Electrical Standard Practices Manual
• 20-4X-XX- Chapters related to standard electrical items and connecting parts with their description (P/N identification and characteristics) and their related processes (connection procedure or connection table) :
The ESPM is broken down into the following:
20-00-00
Introduction and how to use. You will also find an example here, which walks you through the process
Part Number (P/N) Construction
NOTE : For ASN standards, the 3 letters A,S,N are omitted in the P/N.For clarity, only the suffix (item)(e.g. TC0607) is shown in the tables. The full P/N is however identifiable since the applicable standard
Part Number (P/N) Construction
It is only with a P/N (not with a FIN) that it is possible to access to the ESPM information. The P/Ns listed in the ESPM are made up of two parts: - A basic element which is the standard number/family. - A suffix which defines the item. e.g.basic element(standard) + suffix(item) = Full P/N NSA936504 ASNE0261 TC0607 CF24 NSA936504TC0607 E0261CF24
20-10-00
Relates to safety issues. Here also you have ability to print yourself a safety tag.
20-25-00
Relates to tools used.

Electrical Standard Practices Manual
The ASM contains the following:
-Simplified Schematics : Have schematic symbols but do not show sufficient detail to permit fault isolation. -Schematics : Show all line replaceable items, all A/C wiring, within a sub-sub system and give sufficient depth for A/C fault isolation. Note: Applicable to the particular customer or group of customers.
number is always mentioned on the page (in the title or/and on top
of the table). NOTE : For tool military part number (MIL), the P/N shall consist of the letter M and of the basic specification number.
The Wiring Diagram Manual
The WDM consists of the following:
ASM - Aircraft Schematic Manual
AWM - Aircraft Wiring Manual
AWL - Aircraft Wiring List

Routing of wiring for safety, redundancy and reduction of EMF induction are described here.
These areas are further divided into 6 designations;
“G” for power generation of AC and DC. “P” for power distribution of greater than 15 amp circuits. “M” for miscellaneous non-sensitive circuits less than 15 amps. “S” for sensitive circuits such as FLT CTRL. “R” for radio audio and antennas. “T” for coax
