Product Description
The On-Site Guide (BS 7671:2018+A2:2022) is the Institution of Engineering and Technology (IET) spiral-bound field companion to the 18th Edition IET Wiring Regulations, covering installations up to 100 A three-phase for electricians working to British Standard BS 7671.
BS 7671 is the UK wiring standard, and the On-Site Guide is the book most UK electricians actually carry. It condenses the regulations into cable sizing tables, maximum circuit lengths, inspection and testing procedures and installation guidance. This printing includes Amendment 2 (2022), which added electric vehicle charging guidance, protection against thermal effects and voltage disturbances, and the new chapter on prosumer installations covering energy storage, smart-grid interfaces and renewable sources.
What's included
- On-Site Guide to BS 7671:2018+A2:2022, published by the IET
- Spiral-bound, lies flat on site
- ISBN-13 9781839532276
- Part of the IET Electrical Regulations series
- Covers Amendment 1 (2020, EV charging) and Amendment 2 (2022)
Who it's for
Electricians and installers working to BS 7671 in the United Kingdom or on British-standard projects abroad, candidates for City & Guilds 2382 and 2391 courses, electrical apprentices in UK-style programs, and US engineers who need a practical reference for comparing UK wiring practice with the NEC.
Why this edition
Amendment 2 is the version in force, so an older A1 or 2018 On-Site Guide no longer matches current UK requirements. The spiral binding is the practical choice for a book that gets opened on a van bonnet. Note that this is a UK document: electrical work in the United States is governed by the NFPA 70 National Electrical Code, which we also stock.
Frequently asked questions
Is the On-Site Guide the same as BS 7671?
No. BS 7671 is the full regulations book. The On-Site Guide is the IET’s condensed companion for everyday installations up to 100 A three-phase; most electricians own both.
Does this edition include Amendment 2?
Yes. This is the BS 7671:2018+A2:2022 printing, which incorporates both the 2020 and 2022 amendments.
Can I use this for electrical work in the United States?
Not as a code reference. US installations follow the NEC. This guide is for work to UK standards or for study and comparison.
