a lil bit of the history of the UK electrical regs
Requirements for safe wiring date back to 1876 when Mr Musgrave Heaphy, an engineer with the Phoenix Assurance Company, started investigating the possible fire risks from the installations of electrical systems. In June 1882, the Society of Telegraph Engineers and Electricians, which later became the Institution of Electrical Engineers, published the Rules and Regulations for the Prevention of Fire Risks arising from Electric Lighting. This first edition of the IEE Wiring Regulations was a simple four-page document, but has now become the technical standard for all installers carrying out electrical installation work. In 1991 it became British Standard 7671: Requirements for Electrical Installations.
