British Standard BS 7671 "Requirements for Electrical Installations. IET Wiring Regulations", informally called in the UK electrical community "The Regs", is the national standard in the United Kingdom for electrical installation and the safety of electrical wiring systems
SCOPE of BS 7671
The regulations in BS7671 applies to the design, selection, erection and verification of electrical installations within;

commercial properties
public premises
industrial premises
prefabricated building
low voltage generating sets
highway equipment and street furniture
locations containing a bath or shower
rooms or cabins that contain a sauna
swimming pools and other basins
construction and demolition sites

caravans and motor caravans
temporary installations for structures, amusement devices/booths at fairgrounds, amusement parks, circuses and professional stage and broadcast applications

BS 7671 only covers electrical systems that the IET defines as those covered by the following. Circuits supplied at a nominal voltage up to, but not exceeding 1000V AC or 1500V DC. For AC the preferred frequencies of the supply are 50Hz, 60Hz and 400Hz. The use of other frequencies for special purposes in not excluded. Part 2 Definitions the voltages covered by BS7671 are defined thus. Voltage, nominal (U0). The voltage by which an installation (or part of an installation) is designated and the following ranges of nominal voltage (rms values for AC) are defined
Extra low. Not exceeding 50V AC or 120V ripple free DC, whether between conductors or Earth
Low. Exceeding extra low voltage but not exceeding 1000V AC or 1500V DC between conductors or 600V AC or 900V DC between conductors and Earth. High. Voltages that normally exceed those of Low voltage. It did not become a recognized British Standard until after the publication of the 16th edition in 1992. The standard takes account of the technical substance of agreements reached in CENELEC. The current version is BS 7671:2018+A2:2022 (the 18th Edition) issued in 2022, and came into effect from 28 March 2022 (the previous version BS 7671:2018+A1:2020 being withdrawn on 27 September 2022). BS 7671 is also used as a national standard by Mauritius, St Lucia, Saint Vincent and the Grenadines, Sierra Leone, Singapore, Sri Lanka, Trinidad and Tobago, Uganda, Cyprus, and several other countries, which base their wiring regulations on BS 7671.

Составление и публикация
Стандарт поддерживается совместным техническим комитетом IET/BSI JPEL/64, Национальным комитетом Великобритании по правилам электроустановок, и совместно опубликован IET (ранее IEE) и BSI. Несмотря на то, что IET и BSI являются негосударственными организациями, а правила электроустановок не имеют статуса закона, они упоминаются в ряде законодательных актов Великобритании и, в большинстве случаев, для практических целей обладают юридической силой как надлежащий способ выполнения электромонтажных работ. BSI (British Standards Institute) публикует множество изданий, касающихся допустимых стандартов в области проектирования, безопасности и качества в различных сферах.
История стандартов BS 7671 и предшественников
Первое издание было опубликовано в 1882 году под названием «Правила и предписания по предотвращению пожарных рисков, возникающих при использовании электрического освещения». С третьим изданием в 1897 году название стало «Общие правила, рекомендуемые для электромонтажных работ по электроснабжению», с пятым изданием 1907 года – «Правила электромонтажа», и окончательно закрепилось как «Правила для электрооборудования зданий» с восьмым изданием в 1924 году. Начиная с 15-го издания (1981), эти правила стали тесно соответствовать соответствующему международному стандарту IEC 60364. В 1992 году правила электромонтажа IEE были утверждены в качестве британского стандарта BS 7671, что упростило юридическое обеспечение соблюдения их требований как в соответствии с нормами «Электричество на рабочем месте», так и с международной точки зрения. В настоящее время к ним относятся аналогично другим британским стандартам. BS 7671 гармонизируется (и в значительной степени основан) на документах по гармонизации Европейского комитета по электротехнической стандартизации (CENELEC) и, следовательно, технически очень схож с действующими правилами электромонтажа других европейских стран.
Первое издание
Правила и нормы по предотвращению пожаров, вызванных электрическим освещением. Два жилы кабеля – фазный и нейтральный, без заземления. Защита осуществлялась с помощью предохранителя с возможностью замены.
