IEC 60364 is the international standard for low-voltage electrical installations, providing comprehensive, multipart rules for the design, safety, and verification of wiring systems, including specialized requirements for locations like medical facilities and electric vehicle charging. The standard is widely adopted as the foundation for national wiring codes to ensure safety against hazards such as electric shock and overcurrent. For a comprehensive guide, see IEC Installation Guide. Electrical Installation Guide 2018
It sounds like you have been looking into IEC 60364, the international standard for electrical installations in buildings.
Since you found the topic interesting, I wanted to share a brief overview of why this standard is so significant (in case you are just getting started with it) or clarify its structure if you are looking for specific details. iec 60364pdf
Think of IEC 60364 as the "Constitution" for electrical safety in buildings globally. It is published by the International Electrotechnical Commission (IEC).
Unlike the NEC (NFPA 70) used in the United States, which is a very prescriptive book (telling you exactly what wire to use and how to install it), IEC 60364 is often more principles-based. It sets the safety goals and methods, which are then adapted into local national codes (like the BS 7671 in the UK, AS/NZS 3000 in Australia, or IS 732 in India).

Accessing a PDF version of IEC 60364 can be done through several channels:
Official IEC Website: The International Electrotechnical Commission's official website often provides access to standards for purchase. You can buy the entire series or individual parts in PDF format. Initial and periodic inspection and testing
National Electrotechnical Committees: Many countries have their own national electrotechnical committees that may distribute IEC standards, sometimes including translations.
Libraries and Standards Repositories: Some libraries, especially those associated with engineering or technical institutions, may have copies of IEC standards for reference. Online repositories and databases like IHS Standards Store, ANSI Webstore, or national standards bodies may also offer the standards for purchase or under a subscription model.
Preview or Free Samples: Some standards bodies offer preview versions or free samples of standards. However, these are typically limited.
