IEC 60445:2017 Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors
IEC 60445:2017 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. This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
It has the status of a basic safety publication in accordance with IEC Guide 104.This sixth edition cancels and replaces the fifth edition of IEC 60445, published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a) the text of the introduction has been moved into the scope in accordance with IEC Guide 104;
b) colour codes for the identification of line conductors of DC systems;
c) colour code for the identification of functional earthing conductor;
d) update of Table A.1with colour codes for DC line conductors;
e) conversion of notes containing non-mandatory requirements to normative text;
f) the terminology is aligned with IEC 60050-195.
