IEC 60364Electrical Installations for Buildings is the International Electrotechnical Commission (IEC)'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 electricians 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 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
Section 706: Restrictive conductive locations
Section 708: Electrical installations in caravan parks and caravans
Section 709: Marinas and pleasure craft
Section 710: Medical locations
Section 711: Exhibitions, shows and stands
Section 712: Solar photovoltaic (PV) power supply systems
