Colour Code According To DIN VDE 0293: 1) Multicore Flexible Cables

The document describes color coding standards for electrical cable cores according to DIN VDE 0293-308. It provides color coding schemes for multicore flexible cables, multicore cables for fixed installation, and multicore cables with concentric conductor for fixed installation, based on the number of cores. Single core cables use black or green-yellow cores. Core markings may also include white numbering, with specifications on height, gap size, and other dimensions.

Single core cables


The core-colour of single core sheathed cables is black or green-yellow.

* This type contains altogether 6 conductors, see DIN VDE 0293 section 5,1 ** see DIN VDE 0293 section 5,1

Core marking with numbering (in direction to longitudinal axis)

*) when the number is only 1, the smallest breadth is half of the given dimension to this column.
1 ) Please Request: Identification of cable cores/connections and flexible connections in colour according to: DIN VDE 0293-308, HD 308 S2 (to be changed 01.04.2006). In comparison with DIN VDE 0293 (VDE 0293):1990-01 the following changes occurred: * Separation of the requirements for core identification into the different standards, that is: By colour as in the standards, By imprinting according to DIN EN 50334 (VDE 0293 Part 334); * Use of the same colour code for fixed and flexible connections; * Core colour gray to be used instead of black in multicore cables, which previously contained two black cores; * For neutral connections, only single cable, connections with a blue core may be used.
