IEC 60364 Electrical Installations for Buildings is the International Electrotechnical Commission's international standard on electrical installations of buildings. This standard is an attempt to harmonize national wiring standards in an IEC standard and is published in the European Union by CENELEC as "HD 60364". The latest versions of many European wiring regulations (e.g., BS 7671 in the UK) follow the section structure of IEC 60364 very closely, but contain additional language to cater for historic national practice and to simplify field use and determination of compliance by electrical tradesmen and inspectors. National codes and site guides are meant to attain the common objectives of IEC 60364, and provide rules in a form that allows for guidance of persons installing and inspecting electrical systems.

The standard has several parts:

  • Part 1: Fundamental principles, assessment of general characteristics, definitions
  • Part 4: Protection for safety
    • Section 41: Protection against electric shock
    • Section 42: Protection against thermal effects
    • Section 43: Protection against overcurrent
    • Section 44: Protection against voltage disturbances and electromagnetic disturbances
  • Part 5: Selection and erection of electrical equipment
    • Section 51: Common rules
    • Section 52: Wiring systems
    • Section 53: Isolation, switching and control
    • Section 54: Earthing arrangements, protective conductors and protective bonding conductors
    • Section 55: Other equipment (Note: Some national standards provide an individual document for each chapter of this section, i.e. 551 Low-voltage generating sets, 557 Auxiliary circuits, 559 Luminaires and lighting installations)
    • Section 56: Safety services
  • Part 6: Verification
  • Part 7: Requirements for special installations or locations
    • Section 701: Electrical installations in bathrooms
    • Section 702: Swimming pools and other basins
    • Section 703: Rooms and cabins containing sauna heaters
    • Section 704: Construction and demolition site installations
    • Section 705: Electrical installations of agricultural and horticultural premises
