ES 2: How to Design Control Panels according to EN 60204-1

Last edit: 27/08/2025

Training Objectives

The training objective is to be able to design and engineer an industrial control panel according to the European Standard EN 60204-1. Since October 2021, the 2006 edition of EN 60204-1 is not anymore harmonised and the new edition has become compulsory. We will also touch on the new editions of IEC 61439-1 and IEC 61439-2 (2020).

Finally, we will go into detail about the Neutral earthing systems: TN, TT and IT, we will address the issue of bonding of Exposed Conductive Parts and the problem of extraneous conductive parts.

Despite adhering to the language of the standard, the training is practical, with several examples.
