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. 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, definitionsPart 4: Protection for safetySection 41: Protection against electric shockSection 42: Protection against thermal effectsSection 43: Protection against overcurrentSection 44: Protection against voltage disturbances and electromagnetic disturbancesPart 5: Selection and erection of electrical equipmentSection 51: Common rulesSection 52: Wiring systemsSection 53: Isolation, switching and controlSection 54: Earthing arrangements, protective conductors and protective bonding conductorsSection 55: Other equipmentSection 56: Safety servicesPart 6: VerificationPart 7: Requirements for special installations or locationsSection 701: Electrical installations in bathroomsSection 702: Swimming pools and other basinsSection 703: Rooms and cabins containing sauna heatersSection 704: Construction and demolition site installationsSection 705: Electrical installations of agricultural and horticultural premisesSection 706: Restrictive conductive locationsSection 708: Electrical installations in caravan parks and caravansSection 709: Marinas and pleasure craftSection 710: Medical locationsSection 712: Solar photovoltaic (PV) power supply systemsSection 713: FurnitureSection 714: External lightingSection 715: Extra-low-voltage lighting installationsSection 717: Mobile or transportable unitsSection 718: Communal facilities and workplacesSection 721: Electrical installations in caravans and motor caravansSection 722: Supplies for Electric VehiclesSection 729: Operating or maintenance gangwaysSection 740: Temporary electrical installations for structures, amusement devices and booths at fairgrounds, amusement parks and circusesSection 753: Heating cables and embedded heating systems
