Cable colours:

1. Cable colours: Um die einzelnen Leitungen einfacher auseinander zu halten, wird ein Farbsystem verwendet, mit welchem die einzelnen Leitungen gekennzeichnet sind. Je nach Herkunftsland und Alter des Fahrzeugs können diese Farben sich unterscheiden, die hier angegebenen Farben sollten sich aber in jedem deutschen Fahrzeug, das nach dem 2. Weltkrieg gebaut wurde, wiederfinden (wie in der DIN 72551 festgelegt).

Viele Leitungen sind zweifarbig. Die erste Farbe (Grundfarbe) dient zur Feststellung des Verwendungszwecks, die zweite Farbe (Kennfarbe) dient zur Identifizierung der speziellen Leitung (z.B. Blinker links/rechts). Die Kennfarbe ist meist in Form einer (verdrillten) Linie oder Ringen auf der Leitung angebracht.

Wire cross-sections

2. Wire cross-sections The most common cable cross-sections in vehicles are 0.5, 0.75, 1.0, 1.5, 2.5, 4, 6 and 10mm2. For single laid wires cable cross-sections above 1 mm2 are recommended for stability issues. For cable bundles the single wires may be thinner. There are two rules of thumb for wire cross-sections:  

max. 5A/mm2 for permanent load max. 10A/mm2 for short-term load

If the load limit for a wire is achieved, the next bigger cross-section should be chosen especially for longer wires.

Examples for cross-sections to use: Current
