![]() It is a consensus code considering suggestions from interested parties. States, counties or cities often include the NEC in their local building codes by reference along with local differences. Since 1897 the US National Fire Protection Association, a private non-profit association formed by insurance companies, has published the National Electrical Code (NEC). The first electrical codes in the United States originated in New York in 1881 to regulate installations of electric lighting. BS 7671 is the standard to which the UK electrical industry adheres, and compliance with BS 7671 is now required by law through the Electricity, Safety, Quality and Continuity Regulations 2002.įurther information: Electric power distribution § Secondary distribution, and Electrical wiring in North America In 2018, the 18th edition of the wiring regulations BS7671:2018 was released and came into force in January 2019 and BS7671:2018 Amendment 2 was issued March 2022. The 17th edition (issued in January 2008) included new sections for microgeneration and solar photovoltaic systems. In the United Kingdom, wiring installations are regulated by the Institution of Engineering and Technology Requirements for Electrical Installations: IEE Wiring Regulations, BS 7671: 2008, which are harmonised with IEC 60364. DIN VDE 0100 is the German wiring regulations document harmonised with IEC 60364. The German Commission for Electrotechnical, Electronic, and Information Technologies of DIN and VDE (DKE) (Deutsche Kommission Elektrotechnik Elektronik Informationstechnik in DIN und VDE) is the organisation responsible for the promulgation of electrical standards and safety specifications. By contrast, national codes, such as the NEC or CSA C22.1, generally exemplify the common objectives of IEC 60364, but provide specific rules in a form that allows for guidance of those installing and inspecting electrical systems. Neither is it designed for field use by electrical tradesmen and inspectors for testing compliance with national wiring standards. However, this standard is not written in such language that it can readily be adopted as a national wiring code. Hence national standards follow an identical system of sections and chapters. In European countries, an attempt has been made to harmonise national wiring standards in an IEC standard, IEC 60364 Electrical Installations for Buildings. The standard is mandatory in both New Zealand and Australia therefore, all electrical work covered by the standard must comply. In Australia and New Zealand, the AS/NZS 3000 standard, commonly known as the "wiring rules", specifies requirements for the selection and installation of electrical equipment, and the design and testing of such installations. They are usually based on a model code (with or without local amendments) produced by a national or international standards organisation, such as the IEC. Wiring installation codes and regulations are intended to protect people and property from electrical shock and fire hazards.

Wiring codes of practice and regulations ![]() The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist. ![]() Wiring safety codes vary by locality, country, or region. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.Īssociated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring is subject to safety standards for design and installation. ![]() Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. ![]()
