Applies to AC circuits up to 1000V and DC circuits up to 1500V.
This section lays the groundwork. It outlines the basic objectives of the standard, such as protection against electric shock, thermal effects, overcurrent, and undervoltage. Part 4: Protection for Safety
This hierarchical relationship—from —ensures a consistent level of safety across jurisdictions while allowing for local variations. For professionals working internationally, having access to the "iec 60364.pdf" is essential, as it represents the pure, unmodified source standard.
A new edition of Part 7‑712, covering solar photovoltaic (PV) power supply systems, was published in October 2025. This edition includes updated requirements for electrical installations resulting from PV systems, as well as requirements relating to the installation of energy storage systems (e.g., batteries). iec 60364.pdf
IEC 60364 is a multi-part standard. Major parts include:
BS 7671 (The IET Wiring Regulations) is almost entirely aligned with IEC 60364.
This section is critical for safety engineering, focusing on mitigating various operational hazards: Applies to AC circuits up to 1000V and
The source neutral is grounded. The exposed conductive parts of the installation are connected to a completely separate local earth electrode. Residual Current Devices (RCDs) are mandatory in TT systems to ensure automatic disconnection during an earth fault. IT System (Isolé-Terre)
Standard industrial and residential networks. Offers high fault current for fast breaker trips. Directly earthed at the transformer. Connected to local independent earth electrodes.

IEC 60364 is an international standard that provides harmonized rules for the design and installation of electrical systems. It applies to residential, commercial, industrial, and public premises. The standard specifically governs systems operating at voltages up to: (Alternating Current) 1500 V DC (Direct Current)
IEC 60364 provides guidelines for electrical installations in buildings, including:
The most direct source is the (webstore.iec.ch), where you can purchase individual parts of the standard in PDF format. Prices vary depending on the part and edition. For example, a consolidated version of IEC 60364-1:1972+AMD1:1976 (historical) is available for CHF 50, while current editions are priced higher. As of 2025, the most recent sixth edition of Part 1 (IEC 60364‑1:2025) is available for purchase from the IEC Webstore and from national standards bodies such as ANSI, BSI, DIN, and others.
