The standard is not a single document; it is a multi-part series partitioned into distinct segments. These focus on the lifecycle of an electrical installation, from fundamental conceptual design to final field testing.
When consulting an , you will typically find detailed guidance on:
What are you designing or installing this electrical system for? iec 60364.pdf
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
The IEC 60364 series has evolved over five decades. The first edition of Part 1 dates back to , with editions published in 1972, 1992, 2001, 2005, and most recently 2025 . Using an outdated edition—such as the 2001 or 2005 edition—could result in an installation that does not comply with current safety requirements, particularly for modern technologies like photovoltaic systems, electric vehicle charging, and energy storage. The standard is not a single document; it
Following IEC 60364 ensures that electrical installations are safe and meet international standards, which is vital for multinational projects. It is designed to: Ensure safety against hazards. Ensure the proper functioning of the installation.
Wiring systems (current-carrying capacities, voltage drop limits, and installation methods). Part 5-54: Earthing arrangements and protective conductors. Part 6: Verification This section lays the groundwork
This critical section outlines how to protect against electric shocks, thermal effects, overcurrent, and voltage disturbances. It is essential for determining grounding systems (TN, TT, IT). 3. IEC 60364-5: Selection and Erection of Equipment
IEC 60364 serves as the international standard for low-voltage electrical installations, focusing on safety, reliability, and modern efficiency requirements. The standard covers essential guidelines for protection against electric shock, along with updated regulations for energy efficiency and specialized, smart, or renewable energy-equipped buildings.

: This is addressed through measures such as automatic disconnection of supply (using overcurrent protective devices and RCDs), electrical separation, and the use of SELV (Safety Extra Low Voltage) systems.
