Cables and Leads



The cables and leads are marked with a cable code consisting of three parts:
P15-5 YE/GY 2.5

where:
The first part (P15-5) is the item number. The second part (YE/GY) is the colour code. The third part (2.5) is the conductor cross-section area in sq.mm

Item number
Each lead is designated by a letter followed by a number.

The letter specifies the group to which the system belongs:
^ C Comfort Systems
^ D Diagnostics
^ E Engine Systems
^ G Gearbox Systems
^ I Instrumentation Systems
^ L Lighting Systems
^ P Power Supply Systems
^ Q Anti-Theft Alarm
^ S Safety Systems
^ T Telecom Systems
^ V View Systems
^ W Warning Systems
^ X Other systems

The number is unique except for:
^ 15 = +15voltage
^ 30 = +30 voltage
^ 31 = ground
^ 54 = +54 voltage

Leads with the same letter and number, e.g. E110, E110-1, E110-2, etc., normally belong to the same function.

Cross-sectional Area
The cross-sectional area of the conductor is specified in mm2 and determines the current the cable is capable of carrying.
