IEC 60364 is not a single document but a series of standards divided into several parts, allowing for detailed coverage of specific aspects of electrical installations. The main parts include: Part 1: Fundamental Principles

While countries like the US use the National Electrical Code (NEC), many nations harmonize with IEC 60364. The main difference lies in philosophy: NEC is highly prescriptive (detailed rules for every situation), whereas IEC 60364 is more performance-based, allowing engineering judgment. However, both share the ultimate goal of preventing shock, fire, and equipment damage.

IEC 60364 is the international standard for low-voltage electrical installations, providing a global framework for safe, reliable design and installation. Structured in parts, the standard covers fundamental principles, protection for safety, equipment selection, and specific requirements for special locations.

IEC 60364 is an international standard that provides comprehensive rules for the design, erection, and verification of electrical installations. It focuses on ensuring the safety of persons, livestock, and property against dangers and damage which may arise in the reasonable use of electrical installations. Scope of the Standard

Engineers and electricians search for the for three primary reasons:

A core technical component of IEC 60364 is the strict classification of earthing architectures. The standard uses a two-letter coding system to identify how the power source and the exposed conductive parts of the installation are connected to the Earth. Earthing System Type Source Earthing Connection Equipment Earthing Connection Core Use Case & Characteristic (TN-S, TN-C, TN-C-S) Directly earthed at the transformer.
