The NEC also requires the high-leg conductor of a high-leg delta system to have orange insulation, or to be identified by other suitable means such as tagging.

The United States National Electrical Code requires a bare copper, or green or green/yellow insulated protective conductor, a white or grey neutral, with any other colour used for single phase. Main article: Electrical wiring in North America 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.Ĭolour coding of wiring by region In 2018, the 18th edition of the wiring regulations BS7671:2018 was released and came into force in January 2019 and BS7671:2018 Amendment 1 was issued February 2020. 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.

As part of the North American Free Trade Agreement (NAFTA) program, US and Canadian standards are slowly converging toward each other, in a process known as harmonisation. The Canadian code reprints Chapter 13 of IEC 60364, but there are no numerical criteria listed in that chapter to assess the adequacy of any electrical installation.Īlthough the US and Canadian national standards deal with the same physical phenomena and broadly similar objectives, they differ occasionally in technical detail. The CSA also produces the Canadian Electrical Code, the 2006 edition of which references IEC 60364 ( Electrical Installations for Buildings) and states that the code addresses the fundamental principles of electrical protection in Section 131. Since 1927, the Canadian Standards Association (CSA) has produced the Canadian Safety Standard for Electrical Installations, which is the basis for provincial electrical codes. The proposals are studied by committees of engineers, tradesmen, manufacturer representatives, fire fighters and other invitees. 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. DIN VDE 0100 is the German wiring regulations document harmonised with IEC 60364.įurther information: Electric power distribution § Secondary distribution, and Electrical wiring in North America In Germany, DKE (the German Commission for Electrical, Electronic and Information Technologies of DIN and 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.
