This guide has been written for electrical Engineers who have to design, realize, inspect or maintain electrical installations in compliance with international Standards of the International Electrotechnical Commission (IEC). “Which technical solution will guarantee that all relevant safety rules are met?” This question has been a permanent guideline for the elaboration of this document. An international Standard such as the IEC 60364 “Electrical Installation in Buldings” specifies extensively the rules to comply with to ensure safety and predicted operational characteristics for all types of electrical installations. As the Standard must be extensive, and has to be applicable to all types of products and the technical solutions in use worldwide, the text of the IEC rules is complex, and not presented in a ready-to-use order. The Standard cannot therefore be considered as a working handbook, but only as a reference document. The aim of the present guide is to provide a clear, practical and stepby-step explanation for the complete study of an electrical installation, according to IEC 60364 and other relevant IEC Standards. Therefore, the first chapter (B) presents the methodology to be used, and each chapter deals with one out of the eight steps of the study. The two last chapter are devoted to particular supply sources, loads and locations, and appendix provides additional information. Special attention must be paid to the EMC appendix, which is based on the broad and practical

combining two or more elements. A MIXTURE is a combination of elements or compounds that can be separated by physical means. A MOLECULE is the chemical combination of two or more atoms. In a compound, the molecule is the smallest particle that has all the characteristics of the compound. AN ATOM is the smallest particle of an element that retains the characteristics of that element. An atom is made up of electrons, protons, and neutrons. The number and arrangement of…
