Why a guide to practice? There is a precise conformity on the content of the Standard 61439 in the IEC and EN world of standards. Consequently this document uses the writing IEC 61439 / EN 61439 in the following. Guide 61439 for the practice: 5 steps to a standard-conforming switchgear assembly The guide lists the process of design, assembly and documentation of a low-voltage switchgear assembly in the order of the necessary steps and at the same time assigns to these steps the relevant sections from the standard IEC 61439 / EN 61439.
The application of the guide is focused on the manufacturing of distribution boards up to 630 A and in addition to checklists and instructions regarding the verifi cation of compliance with the maximum temperature rise. IEC 61439 / EN 61439 - New tasks and responsibilities for the electrician IEC 61439 / EN 61439 shows how a low-voltage switchgear assembly, which is safe for the user, can be built. In addition to changes affecting the design of an assembly, the manufacturer of a switchgear assembly is faced with new tasks and responsibilities. Defi nes which documents belong to a low-voltage switchgear assembly and which verifi cations need to be maintained.
Makes statements regarding the rating of the assembly so that a design verifi cation can be maintained.
