Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors
This International Standard applies to the identification and marking of terminals of electrical
equipment such as resistors, fuses, relays, contactors, transformers, rotating machines and,
wherever applicable, to combinations of such equipment (e.g. assemblies), and also applies
to the identification of terminations of certain designated conductors. It also provides general
rules for the use of certain colours or alphanumeric notations to identify conductors with the
aim of avoiding ambiguity and ensuring safe operation. These conductor colours or
alphanumeric notations are intended to be applied in cables or cores, busbars, electrical
equipment and installations.
