18th Edition

The 18th Edition is the term commonly used in the industry when referring to the latest British Standards BS 7671:2018 Requirements for Electrical Installations, IET Wiring Regulations. You may also hear them referred to as ‘wiring regs’. 18th edition regulations apply to electrical wiring systems in commercial, industrial and domestic buildings.

The question will always contain clues that will direct you to the correct section or page of the Wiring Regulations book.
