A practical guide for the complete design of an electrical installation according to IEC 60364 and other relevant IEC standards

The Electrical Installation Guide has been written for electrical engineers who must design, select electrical equipment for, install this equipment into, inspect, or maintain low-voltage electrical installations in compliance with the standards published by the International Electrotechnical Commission (IEC). “Which technical solution will guarantee that all relevant safety rules are met?” Answering this question has always been integral to the creation of this document.


Covering many topics related to electrical installations

Such as voltage drop, electrical safety, cable sizing, electrical calculations, electrical standards, electrical design, electrical protection, circuit breakers, MV/LV substations, earthing schemes, electromagnetic compatibility, power factor correction, harmonics, overvoltage protection…


Written by Schneider Electric’s most talented electrical distribution experts

Sharing their latest state-of-the-art knowledge about new or updated electrical installation standards, technological evolutions…
The Electrical Installation Guide is also available in a Wiki format to let any and all experts contribute to its elaboration.


For anyone involved in commercial, industrial, or domestic electrical installations
