Basic and safety principles for man-machine interface, marking and identification
Identification of equipment terminals, conductor terminations and conductors
(IEC 60445:2021); German version EN IEC 60445:2021 Class/Status:
VDE Art. No.: 0100712
This document 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.
