The 18th Edition of BS7671 introduced UK electricians to the AFDD - Arc Fault Detection Device. Recommended as a means of providing additional protection against fire in regulation 421.1.7 and suggested for use in premises with sleeping accommodation to places which store combustible material.
However just because they are recommended doesn't mean electricians are rushing to fit them. In this video, Gary Hayers suggests they are just a natural extension of increasing standards of circuit protection which has evolved continuously over the last century. Electricians in the US have been fitting the equivalent AFCI's (Arc fault circuit interrupters) for the last 20 years.
Wylex (part of Electrium - Seimens - along with Crabtree) are first to market with a single module device which removes one of the barriers to adopting this technology.
Will AFDD's become mandatory in the 19th edition wiring regulations?
